41 00 ... Corrosion protection
Note. Following repairs, the corrosion protection work already begins with the correct removal of the PVC undercoating, antinoise compound and seam seals. The products recommended by BMW are optimized with regard to corrosion protection.
1.0 Removing sealing materials
| IMPORTANT | Do not burn off PVC material (sealing compound) with a gas burner or similar or heat to temperatures above 180°C. This would generate highly corrosive hydrochloric acid and release harmful fumes. The new lining does not form a satisfactory bond with burnt PVC material which means that subsequent sub-surface rust may set in. |
Remove PVC material with a rotating steel brush, or heat PVC to maximum 180°C with a hot air blower and scrape off with a spatula.
2.0 Corrosion protection of sheet-metal parts
All weld joints sealed off with body sealing compound in original state must be primed and sealed off again thoroughly after repairing. Replace damaged or removed antinoise compounds.
Note. Spray gun required for body sealing compound (order no. 81 49 0 300 887).
Concluding cavity protection is the most important part of all corrosion protection measures.
Use the cavity protection spray only for smaller-scale straightening work where the parts in question are easily accessible.
Use the HRS spray gun with pressure container for all other repairs. Cavity protection agent is available in different container sizes.
Use the relevant probes with tubes for the different cavity areas.
| IMPORTANT | Incorrectly performed cavity protection can, especially in the case of steel/aluminum joints, give rise to a non-calculable product liability and safety risk. |
The best repair is worth nothing if the subsequent cavity protection measures are not conscientiously carried out.
2.1 Cavity protection of steel parts
New doors and lids must be sealed with cavity protection agent after being painted.
New sheet-metal parts or cavities, weld seams and folds formed by new sheet-metal parts must be sealed with cavity protection agent after being painted.
The cavities affected must be sealed with cavity protection agent after all straightening work.
2.2 Cavity protection of aluminum parts
New doors, lids and side panels made of aluminum are not sealed with cavity protection agent.
After all straightening work on aluminum components, the cavities affected must be sealed with cavity protection agent after being painted.
After all welding work (E52 only) on aluminum components, the cavities affected must be sealed with cavity protection agent after being painted.
Cavities, seams and folds formed from new sheet-metal parts must be sealed with cavity protection agent after being painted.

Scheme 14
1.0 Scope of delivery
- Owner's Handbook
- Pressure vessel gun (1) for cavity sealing
- Spray set, consisting of spray hoses: angle nozzle (2) and round spray nozzle (3)
| IMPORTANT | Before start-up, read Owner's Handbook and safety instructions. |
2.0 Start-up
- Open pressure vessel and introduce cavity sealant in form of a 1-litre can.
- Connect spray hose to quick-connect coupling.
- Connect apparatus to compressed air supply.
Working pressure 2-6 bar, max. 8 bar!
3.0 Mode of operation
Note. Unlike previous apparatus, it is possible here to alter the spray pattern with the air flow control screw (large knurled screw)!
- Twisting the air flow control screw in decreases the air flow and thus reduces the material spray mist.
This facilitates optimum working when preserving open components/surfaces.
- Twisting the air flow control screw out increases the air flow and thus the material spray mist (for closed cavities).
- The trigger lever has two stages. Stage 1 - discharge of air only. Stage 2 - discharge of air and material.
- After finishing work, press the first stage to clean the spray hose with compressed air.
- When storing, remember to twist the air flow control screw closed to prevent the material from drying out.
- Clean the gun prior to extended periods of non-use (approx. 2 weeks and upwards).
- To ensure that the spray hoses function properly, do not store the hoses coiled up e.g. in the frame side member area! Store spray hoses stretched out.
4.0 Application examples
- Use the matching spray hoses for the different cavities or surfaces.
- Example - doors and lids: Spray hose with angle nozzle. Reduce air flow to keep spray mist to a minimum.
- Example - frame side member: Long spray hose with round spray nozzle. Depending on the type, increase the air flow slightly.
- Always keep the spray mist to a minimum so as to avoid fouling and bad smells.
5.0 Safety instructions
- Do not inhale spray mist.
- Use only in well ventilated rooms.
- Working pressure max. 8 bar.
41 00 ... Handling airbags and restraint systems
1.0 Airbags and restraint systems
- On vehicles with airbags and restraint systems, observe the relevant safety instructions.
- During straightening work on the body, you will be exposed to the risk of accidental airbag triggering when the battery is connected. Due to this potential hazard, it is essential to disconnect the battery negative lead prior to welding and straightening work. Prior to disconnecting the negative lead, interrogate the fault memories of the control units if necessary.
41 00 ... Handling electrical and electronic equipment
1.0 Battery
- There is a risk of explosion when welding or grinding work is carried out in the vicinity of the battery. The battery must be removed . Prior to removing the battery, interrogate the fault memories of the control units if necessary.
2.0 Control units
- The following hazards are present when the battery is connected: Damage to control units during welding work on the body. Accidental triggering of airbags during straightening work on the body.
Due to these potential hazards, it is essential to disconnect the battery negative lead prior to welding and straightening work. Prior to disconnecting the negative lead, interrogate the fault memories of the control units if necessary.
- Control units are designed for a temperature of 65°C. The temperatures in a spraying booth do not pose any problems. If a vehicle is inside the spraying booth at an indicated temperature of 80°C, the actual temperature of the vehicle will be < or = 60°C (object temperature).
- Protects control units against the effects of heat at temperatures > 65°C (e.g. during welding and drying with an infrared radiator or hot air blower).
3.0 Electric cables and wiring harnesses
- Protect electric cables and wiring harnesses against damage (e.g. during straightening and grinding work).
- Protect electric cables and wiring harnesses against the effects of heat at temperatures > 65°C (e.g. during welding and drying with an infrared radiator or hot air blower).

41 00 ... Information on hazards
1.0 Aluminum
| Hazards / effects | Measures / regulations |
|---|---|
| Repair stage 1: (replacement of bolted parts, dent removal) Repair stage 2: (structural repairs with bonding and riveting) | When a vehicle outer shell is ground, aluminum dust accumulates in small amounts. This dust can be removed with conventional extractor systems. |
| Repair stage 3: (structural repairs with welding) Explosion hazard due to high concentration of fine aluminum dust. Arising e.g. during straight-through grinding of coated parts in the base material and large-surface grinding of bright-finish parts. Explosion hazard due to swirling up of fine aluminum dust in cavities. Created by the necessary, thorough cleaning of machining surfaces and tools before and after machining aluminum. | Avoid high concentration of fine aluminum dust by means of continuous extraction. Use explosion-proof extractor systems. Do not use compressed air when cleaning the work bay. Avoid swirling up dust when cleaning the work area. |
| Spontaneous combustion of fine aluminum dust when ignition and fire sources are drawn in. E.g.: hot splinters, grinding sparks, cigarettes etc. | Do not operate ignition and fire sources in the intake area of extractor systems. |

41 00 ... Installing a cavity acoustic baffle with 2-component PU cavity foam
| IMPORTANT | The cavity foam may only be use for cavity sealing at the points at which cavity sealing is present as standard! |
The following repair represents the replacement of a shaped part for the cavity seal by the use of cavity foam.
This type of cavity sealing is used at points at which shaped parts cannot be used for repairs.
This is the case when large amounts of heat occur (e.g. due to welding, soldering or tin-plating) in the direct vicinity or at the point of the standard cavity sealing.
It is not possible here to install shaped parts for the cavity seal because of the fire risk!
To replace shaped parts with cavity foam at further locations, adopt the procedure shown here and adapt it to the relevant conditions.
It must be ensured that the cavity is completely sealed off.
Note. Check the accessibility for the spraying pipe of the cavity foam to the affected cavity after removing the damaged part.
Properties of cavity foam
- 2-component PU foam, solvent-free.
- Excellent flow capacity, enabling complete sealing of cavities.
- Good strength, preventing slipping in cavities.
- Low water absorption, preventing corrosion.
- Ideal for use as insulating and sealing compound.
Information on dangers/hazards
- Avoid eye and skin contact. Wear protective goggles, solvent-resistant protective gloves and protective clothing.
- Do not inhale. Apply in well ventilated rooms only.
- WARNING: Application time after mixing: within 8 minutes! Completely empty open can after use.
- Remaining amounts which are not used can cause the can to explode on account of a chemical reaction (buildup of heat)! Alternatively, cool the can containing the non-removed remaining amount for several hours in cold water.
- Do not eat, drink or smoke during this operation.
- Keep heat and ignition sources well away.
- Read the manufacturer's information on hazards/dangers (printed on the can) prior to application.
Application instructions
- Use by date on can. Do not use the spray can after the Use by date on the can has expired. After the Use by date the properties of the cavity foam will no longer meet the requirements of the BMW Group.
- Cavity sealing of repair area possible after an air drying time of 1 hour.
- Backing surface must be clean and free from dust, grease, oil and stripping agent.
- Application temperature at least 15°C. Optimally 20°C.
- IMPORTANT: Foam expands many times over as it sets (change in volume).
- Before applying to the vehicle, fill a clearly visible cavity of corresponding size with foam on a used part. This enables an optimal dosage (i.e. spraying time) to be specified for filling the cavity on the vehicle with foam.
- Tape off open passages to visible areas with adhesive tape to prevent foam from escaping.
- Setting takes approx. 30 minutes. Mechanical processing (e.g. drilling, cutting, etc.) is then possible.
- Cavity sealing of repair area possible after an air drying time of 1 hour.
- Remove fresh, non-hardened PU foam with adhesive cleaner 208. Sourcing reference: BMW Parts Service. Hardened PU foam can only be removed by mechanical means (machine).
- Excess, hardened PU foam can be disposed of as residual waste. Cans which are not entirely empty and unused whose Use by date has expired are classed as hazardous waste. Observe country-specific waste-disposal regulations.
- Observe the manufacturer's application instructions (printed on the can).
41 00 ... Materials science
1. Aluminum
1.1 Chassis and suspension components
Read and observe the Notes on chassis and suspension components before handling aluminum.
1.2 Material influences
| Causes | Effects / remedies |
|---|---|
| A galvanic element is created under the effects of moisture by contact with materials such as copper, tin, nickel, iron and zinc. | This plating process causes aluminum to be removed from the joint. This results in surface corrosion or pitting. New parts and accessory parts which have been approved by the BMW Group for aluminum (screws, washers, nuts etc.) have undergone special surface treatment. Such parts must not be replaced by conventional parts. NOTE: Damaged parts lose this protection and must be specially coated or replaced. Damage caused by contact corrosion is excluded from the warranty. |
| Materials also used for work on steel components can implant steel particles in the softer surface of an aluminum component. | Surface corrosion or pitting occurs. A separate tool kit is available for processing/machining aluminum. |
| Surfaces are attacked when fluxing agents are used. | Soldering is not permitted for joining aluminum components. Risk of corrosion from chemical factors. |
| Aluminum/steel grinding dust from adjoining work areas. | This results in surface corrosion. Erection of protective barriers. |
| NOTE |
|---|
| Damaged parts lose this protection and must be specially coated or replaced. Damage caused by contact corrosion is excluded from the warranty. |
MATERIAL INFLUENCES
1.3 Machining properties
| Properties of aluminum compared with steel | Effects |
|---|---|
| Aluminum parts are magnetically neutral. | Attachment with magnetic tools/working aids is not possible. |
| Elasticity is only 1/3 as high. Elongation failure is approx. 50% slighter. | Convertibility is limited in comparison with steel. Overstretching the material results in strain-hardening and an increased tendency of cracking. |
| Electrical conductivity is almost 4 times higher. | Electric welding procedures require different equipment (MIG welding). |
| Material expansion during heating is twice as high. | The material expands more markedly. Shorter heat treatment is necessary for removing dents. |
| Thermal conductivity is 3 times higher. | Heat is drained more quickly. Adjoining working areas are affected more heavily e.g. during welding. |
| Microstructural change between 200°C and 250°C. | Elongation characteristics and thus plasticity are improved. Strength is reduced. IMPORTANT: No heat treatment when working on the vehicle structure! Temperature cannot be monitored to sufficiently exact levels in garages. |
| Aluminum shows no annealing colors. | The melting point is 650°C. Once the melting temperature has been reached, the material begins to flow without any further indications. The temperature can only be estimated by means of the paint coloring and the surface warpage. IMPORTANT: Do not use thermal applicators. Not suitable for garage use because the paint runs too quickly. |

MACHINING PROPERTIES
1.4 Mounting
| Characteristic features of aluminum | Special measures |
|---|---|
| Corrosion (ageing) in damp environments. | Store aluminum parts in a dry place. |
| Contact corrosion in event of contact e.g. with steel parts. | Always store aluminum parts separately or in isolation from steel parts. |
| Susceptibility to paint infiltration. | Do not damage protective surface layer since this would cause oxidation. Failure to comply with this requirement would result in more painting work. |

41 00 ... Position of shaped parts for cavity bulkhead
Cavity sealing is carried out in specific body areas in order to reduce internal noise and to reduce condensate. To do this, shaped parts are inserted in the cavities. These shaped parts adapt themselves optimally due to heating of the body to approx. 180°C by expansion to the shape of the cavities.
Because it is not possible to heat the body to this extent for a body repair, a different procedure has been specified for this situation.

41 00 ... Procedure for folding roof after an accident
The folding roof may be under tension after the vehicle has incurred damage following an accident. Moving the folding roof by hydraulic means may result in irreparable damage. For this reason, the folding roof may only be moved manually until the damaged has been repaired.
| IMPORTANT | It is not possible to check the correct operation of the folding roof on the damaged vehicle. |
Different procedures are required, depending on the degree of damage which the vehicle has incurred. The repair instructions for emergency actuation describe only the complete sequences for manually opening and closing the folding roof.
When removing the roof module and/or the rear end module, it is possible to move the folding roof manually into the necessary intermediate positions in each case.
| WARNING | Risk of injury due to the heavy weight of the folding roof! Since the hydraulic system may have to be depressurized during manual movement of the folding roof, there is an increased risk of injury by trapping. Always secure the folding roof adequately against unintentional movement. |
After body repairs to the vehicle
All the folding roof components screwed/bolted to the body are precisely screwed/bolted to the vehicle at the factory by means of gauges. This affects above all the base plates and mounting brackets of the roof and rear end modules. To minimize extensive adjustment work after a body repair as much as possible, only remove those components which are screwed/bolted to a damaged body part.
- Gauge the base plates only after a body repair to the cowl panel.
41 00 ... Quality standard
- The overall requirements relating to a vehicle can only be implemented by including "all" components. This applies in particular to the body. With regard to an optimum crash result, it is necessary to maintain the structural measures. It is absolutely essential to observe the procedures set out in the repair instructions. Any deviation from these procedures will only be permitted after prior consultation with and approval by BMW. Should you have any questions, please contact the country-specific Hotline. The use of non-approved repair steps or tools may have serious consequences for the structure of the vehicle (e.g. in the event of a crash). In the end, this can result in safety and product liability risks which cannot be calculated. Corrosion protection measures during and after repairs are absolutely essential to maintain the value of the vehicle.
- Use only genuine BMW parts and approved auxiliary devices, materials and operating fluids when carrying out repairs.

41 00 ... Spot-weld bonding steel parts
- The spot-weld bonding process is used starting from the E65 to increase vehicle rigidity. In partial bodywork areas, a 1-component adhesive is applied to the spot flanges and this is followed by resistance pressure spot welding. The adhesive is hardened only after the paint drying process (at approx. 180°C).
- In the case of repairs, adhesive is not applied to the spot flanges. The number of welding spots is doubled as a substitute for the omitted adhesive.
- The following processes are used as a substitute for spot-weld bonding: MAG welding ( M etal A ctive G as welding) Resistance pressure spot welding (referred to in the following and in the repair instructions as spot welding).
- Adhesive is not applied between the spot flanges on new parts in the case of 2- or multi-sheet joints. Areas which cannot be reached by the spot-welding tongs can be joined by MAG spot welding. The number of welding spots is doubled as a substitute for the omitted adhesive. Exceptions (e.g. E65) are described in the relevant repair instructions. Apply welding spots to existing welding spots on new part. This is necessary because the adhesive between the spot flanges of the new part acts as an insulator.
- CAUTION: Extract smoke and fumes during welding work.

41 00 ... Straightening steel parts
1.0 Recommended tools
Only use those tools designed for steel repairs.
2.0 Straightening outer shell
- "Cold" straightening: Press dents out from their center and smooth in an inwards direction with gentle taps. In the case of small, soft dents (hail and parking damage), this is also possible without damaging the paintwork. This work requires a special tool (5 04 98 328) and a trained worker.
- "Hot" straightening: Heat dents in their central point only with a gas flame until bright red hot. Then quench the material with a wet cloth.
- Stud welding can be used in the case of damage where access is only possible from one side. Weld on the stud in the middle of the damaged area. The steel pin or shim is driven out using a hammer until the depression is removed. The stud, pin or shim is then ground or twisted off.
- Avoid cracking.
- Avoid hardening and overstretching.
- Avoid heating and overheating the outer shell over large areas.
- If, after steel parts have been straightened, the surface shows no dents larger than 2 mm, these dents may be touched up with knifing filler. Dents larger than 2 mm must be treated with filling solder. NOTE: Only applicable within the European Union! European used-car regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003!
- For safety vehicles, follow the special notes and information in the repair instructions.
3.0 Straightening structure
- Repairs affecting the mounting points of assemblies and chassis/suspension components must be carried out on the straightening bench with the matching straightening attachment set or specification sheet for the vehicle. Straightening attachments and specification sheets are also available for the top section, e.g.: door pillars, convertible top mounts, cowl, rear lid hinges, etc.
- Check windshield and rear window apertures for curvature by inserting the original glass.
- Take the gap dimensions for doors, engine hood and rear lid from the vehicle-specific gap dimension diagram.
- Bearing body components such as e.g. engine carriers, door pillars, frame side members etc. with deformations which can no longer be returned to their original shape by "cold straightening" must be replaced. Heating bearing body components for better reshaping is not permitted! Failure to comply with this requirement would result in a loss of original strength of up to 40 %.
- High-strength and super-high-strength steel plates as a rule cannot be reshaped. Reshaping only serves as a preparatory measure to replacing the component in order to achieve optimal joining of the connection points.
- The body must be anchored as follows for reshaping: If using vehicle-specific/universal straightening attachment sets (Carbench/ Celette), it is necessary to secure the body additionally with 4 retaining clips to the spot flange of entrance or to the 4 jacking points. The spot flange (if available) is to be preferred. If using universal electronic or mechanical straightening systems (Car-O-liner/ Celette), it is necessary to secure the body with 4 retaining clips to the spot flange of entrance or to the 4 jacking points. The spot flange (if available) is to be preferred. In addition anchor at least 2 points with the securing set. Failure to comply with these instructions will result in damage to the body during reshaping in non-damaged areas. Vehicle-specific straightening attachments and universal mounts may be damaged.

MATERIAL CHART
41 00 ... Vehicle identification number, general
The vehicle identification number must be stamped with a special tool. There are different special tool numbers and stamping procedures for the various vehicles. Refer to the relevant repair instructions.
In repair work, the vehicle identification number is always stamped into a replacement vehicle identification number surface. The replacement surface is usually situated under the original VIN surface.
The IGEF number (bodyshell number) is omitted when the wheel arch is replaced.
In the event of component or body replacement by the BMW garages/workshops, clearly delimit the vehicle identification number at front and rear by stamping a + in place of the BMW emblem.
If a VIN is stamped into the replacement surface in addition to the original VIN (e.g. if the original VIN has been tampered with), the following applies: The original VIN must be crossed out. To do so, stamp the letter I from the punch digits lengthways through the original VIN.
| IMPORTANT | Do not use an angle grinder in conjunction with a cutting disk! |
The protective film used as standard is omitted after the VIN has been manually stamped in. Paint area in accordance with BMW Painting Handbook. Ensure that layer thicknesses are small.
Observe country-specific regulations.
41 00 ... Welding and soldering steel parts
- Welding steel parts: General information The following procedures are used for repairs: MAG welding ( M etal A ctive G as welding) Resistance pressure spot welding. Take the number and location of weld spots and MAG weld seams from the separated part. Replace areas inaccessible to spot-welding tongs with MAG plug/spot welds at the same distance. Diameter of bores for plug/spot welds 8 mm. In the case of emissions extraction, observe a minimum distance of 30 cm for MAG welding during the welding process. Otherwise the inert gas would be drawn off. Follow the equipment manufacturer's instructions for use. Work materials MAG welding: Steel welding apparatus. Steel welding wire - G3SI1 (SG2) or alternatively G4SI1 (SG3) Welding mask Gas bottle containing inert gas (82 % argon, 18 % CO 2 ) Resistance pressure spot welding: Spot-welding apparatus. Protective goggles Preparations for MAG and spot-welding Remove the paint coating in an area of approx. 30 mm around the weld seam or spot. The zinc coating underneath must be removed during the MAG welding operation. It is not necessary to remove the zinc coating underneath during spot-welding. Remove the paint coating on the reverse side of the weld seam or spot. Contaminants will otherwise enter the weld pool via the root of the weld seam. An insufficient electron flow prevents an optimum spot-weld joint. Coat all metal overlaps and weld spot flanges with welding primer. To determine the optimum electrode contact force for spot-welding, carry out spot-weld shear tests on sample metal sheets. In order to keep the electron flow short during MAG welding on the body, you must if possible attach the ground terminal directly to the component to be welded. Welding During MAG welding, the weld gap must be kept as small as possible. The larger the weld gap, the lower will be the strength of the joint. During spot-welding, the metal flanges to be joined must be placed as close together as possible without gaps. The larger the gap, the lower will be the strength of the joint. Minimum gap between welding spots 25 mm. Subsequent treatment of weld joints: When grinding a weld seam, do not grind thin the base material next to the seam. After joining, clean all weld seams and spots with a stainless steel wire brush. Remove burnt paint with a stainless steel wire brush. All weld joints sealed off with body sealing compound in original state must be primed and sealed off again thoroughly after repairing. Replace damaged or removed antinoise compounds.
- Soldering steel parts: General information The following procedures are used for repairs: Gas brazing Tinning The MIG soldering procedure is not used in repairs for strength reasons. MIG soldered/brazed seams used in series production are replaced in repairs by MAG weld seams. Areas brazed in vehicle production are joined during repairs with the same procedure. It is possible when straightening steel parts to correct irregularities smaller than 2 mm with filler. If in exceptional cases the irregularities are in excess of 2 mm, these areas must be tinned. Only visible areas of the outer skin and on the support carrier must be tinned. All areas which have covers on the vehicle are not to be tinned. NOTE: Only applicable within the European Union! European used-car regulations prohibit the use of tin containing lead in motor vehicles introduced after 01.07.2003! Work materials Gas brazing: Tube pack and torch (gas torch) Brazing solder Gas bottles (oxygen and acetylene) Welding goggles Tinning: Tube pack and torch (torch for tinning) Tinning paste Tin. Gas bottle (acetylene) Protective goggles Preparations for brazing/tinning Heat brazed joints to be opened with an autogenous flame. Lift off remaining metal and remove remaining brazing solder with a wire brush. Remove the paint and zinc coating in an area of approx. 30 mm around the seam to be soldered. Remove the paint and zinc coating in the tin-plating area and approx. 30 mm beyond. Brazing/tinning Execute brazed seam without overheating the solder and with low heat dissipation. If necessary, use heat protecting paste. Subsequent treatment of brazed joints: Remove burnt residual zinc completely. Straighten, grind and tin visible connection points. Remove burnt paint with a stainless steel wire brush.

WORKSHOP EQUIPMENT CHART
| IMPORTANT | In vehicles from model year 2001, higher-tensile and high-tensile steels are used in certain areas. It is essential to check whether the spot-welding apparatus used conforms to the technical requirements of the currently recommended welding sets. Should you have any questions, please contact the country-specific Hotline. The use of technically obsolete equipment may have serious consequences for the structure of the vehicle (e.g. in the event of a crash). In the end, this can result in safety and product liability risks which cannot be calculated. |
