Strut leak
Struts are frequently rejected and exchanged because of leaks. Examinations on test stand and on the vehicle have shown that the replacement of a large number of rejected strut was not justified.
Slight leaking of oil ("sweating") at piston rod seal is no reason to replace a strut. A strut with oil is OK under the following circumstances
Scheme 7
- Oil leak (shown screened in illustration) is visible, but dull, matte and possibly dry from dust
- Oil leak reaches at most, from upper shock absorber seal (piston rod seal) to lower spring plate - arrow -.
Note. A slight oil leak is advantageous because it lubricates the piston rod seal and extends its service life. This applies to struts on front and rear axles
Strut, noises
Struts are frequently rejected and exchanged because of rumbling noises. Examinations on the test stand and vehicle have shown that there was not a complaint with approx. 70% of the rejected shock absorbers and the replacement was not justified.
With complaints that are interpreted as rumbling or knocking sounds, proceed as follows.
- Determine on a road test with the customer - if possible on a dry stretch of road with irregularities - where, when and how these sounds change.
Note. In the rarest cases, the strut is the cause of the noises.
Strut, checking while removed
Faulty struts are noticeable when driving due to loud rumbling noises - a result of wheel hopping - especially on poor stretches of road. Moreover, they can be recognized by a large loss of oil.
Note. Struts are maintenance-free, shock absorber oil cannot be topped off.
A removed strut can be checked by hand as follows
- Press strut together by hand.
- Piston rods must move smoothly and with uniform difficulty over the entire range
- Release piston rods.
- On struts with sufficient gas pressure, piston rods return to initial position by themselves.
Note. If this is not the case, strut must be replaced. As long as there is no large loss of oil, the mode of operation corresponds to that of a conventional strut. The damping function is also completely available without gas pressure, as long as there is no large loss of oil. However, noise may increase.
Struts, testing on shock tester
Struts can be checked while installed using the shock tester (strut testing device). The damping effect can be evaluated based on the dial reading or print-out.
Special tools, testers and auxiliary items required
- Boge shock tester or
- Sachs shock tester V.A.G 1975 or
- Maha shock absorber tester VAS 1990
Note. Temperature +10 to +40°C. Driver in vehicle. Tire pressure OK. Drive vehicle straight onto center of wheel contact plates. Front wheels in straight position. Parking not engaged, foot brake not activated.
Threshold
Strut condition can only be judged as follows
- Sufficient damping effect
or
- Insufficient damping effect
Note. Intermediate values for reduced damping performance cannot be read out. A prognosis on service life is not permitted. Measured values that come about from involvement of suspension travel end stops are incorrect.
The following values apply only to the test stands named above. If the specified values are exceeded, the strut action has weakened enough that a replacement is recommended.
Scheme 8
Example
Threshold = 70
- a = greater than 70: Insufficient damping effect
- a = less than 70: Sufficient damping effect
Strut combination installed in vehicle is indicated by corresponding PR number on vehicle data plate.
Clarification of weight Production Relevant numbers (PR no.) Clarification of Production Control numbers (PR No.)
Threshold "a" in mm
Note. If the readout value is greater than the limit value "a" (table value): Damping effect insufficient --> replace strut. If the readout value is less than the limit value "a" (table value): Damping effect sufficient --> strut does not need to be replaced.

Damaged threads, repairing
Damaged threads can be repaired with wire inserts (Heli-Coil).
See component overviews to learn which threads can be repaired.
Shavings that remain in the body must be imbedded in wax.
Longmember thread, servicing
It is possible to service the threads of weld nuts in longitudinal member depending on certain conditions.
- Servicing work may only be performed once per thread.
- If servicing is necessary after this, the nuts must be replaced.
| CAUTION | When drilling, it is essential that eye protection be worn! |
- Have thread repair checked by the responsible foreman or next person in charge.
- Thread insert must be same length as thread in body.
- Correct any damage to the underbody sealant layer.
General Information
When installing waxed components, contact surfaces must be cleaned. Contact surfaces must be free of wax and grease.
Torque specifications for unoiled bolts and nuts are given.
Welding or straightening operations are not permitted on load-bearing or wheel-controlling components.
Always avoid the following actions with coil springs: Hammer stroke, welding beads, applying color identification later.
Do not perform any welding or grinding (separating work) in coil spring or suspension strut area! Cover coil spring or suspension struts if necessary.
Vehicles without drive axle must not be moved, otherwise wheel bearing will be damaged. If vehicle must be moved, observe the following
- Install an outer joint in place of the drive axle.
- Tighten outer joint to 115 Nm (screw M14) or 200 Nm (screw M16).
Bonded rubber bushings have a limited torsional range. Only tighten threaded connections at control arms if vehicle is in curb weight position --> Wheel bearing, lifting to curb weight position
If the vehicle must still be aligned, every bolt and nut that must be loosened for adjustment is only tightened to torque specification. After measurement/adjustment is complete, tighten bolts and nuts to prescribed additional torque angle.
| CAUTION | If vehicle will be driving on the streets, all bolts and nuts must be tightened properly! |

To function properly, the automatic vertical aim control system needs information about compression travel or rebound travel at the front and rear axles.
For this, the position of the lower left link relative to the body is transferred to Left Front Level Control System Sensor G78 via a coupling rod. This transmits electrical signals to the Headlamp Range Control Module J431.

- 94 LIGHTS, SWITCHES - EXTERIOR for ELECTRICAL EQUIPMENT, CABRIOLET
On the rear axle, the signals are transmitted to Headlamp Range Control Module J431 from G76 Left Rear Level Control System Sensor G76.
These signals are required for determining vehicle level.
The automatic headlight range control reacts independently to changes in vehicle level.
The vehicle level can change in the following situations
- Towing a trailer
- Different load conditions; vehicle empty, vehicle partially or fully loaded
- Slow or fast driving habit
| CAUTION | Adjustment of headlights! |
Checking the headlight basic setting is necessary when
- The track control link has been removed and reinstalled or replaced
- Assembly work was performed on level control system sensor
- The level control system sensor was replaced
- The retaining clip for the coupling rod on track control link has been loosened.

Constant velocity joint, checking for function
Constant velocity joint is properly assembled, if ball hub can be slid back and forth by hand over whole compensation length.
Only approved oil should be used for filling or topping off.
To attach or detach charging device V.A.S 6209/2 , system line to be checked must be locked at central valve to limit the quantity of oil leaked to a minimum and to prevent pressurized central valve from emptying.
Before removal or separation, the corresponding line for every DRC component is to be locked at central valve. If work on DRC with unlocked central valve results in even a small amount of oil, a system pressure check with comparison to specified values must be performed in every case. If minimum pressure is not met, central valve must be replaced.
Small oil leak with locked central valve which results from connecting or disconnected charging device V.A.S 6209/2 at connection is not critical. Avoid repeating measurements because a small quantity of oil is removed from the system every time V.A.S 6209/2 is connected. Every connection results in a pressure decrease of approx. 0.3 bar from the previous reading. In this way, multiple repeats of measurements cause pressure to fall below minimum level or malfunction.
Dampers and lines are delivered empty as replacement parts.
Filling must only be done at room temperature (approx. 20° Celsius).
Dampers must only be filled when installed.
Vehicle must never be placed on wheels with closed, filled system and locked central valves. This inevitably leads to leaks and system malfunction.
Lines must not be bent.

Wheels, tires
This information is contained in AESIS; Library; Additional Information; Wheels and Tire Guide
Observe notes about usage in your Owners Manual.
Damaged wheel electronics or valves should be replaced for safety reasons.
Do not clean wheel electronics with steam blasting or strong compressed air.
Replace wheel electronics after using tire sealant as the accumulation of sealant on the pressure sensor can cause false readings.
The Tire Pressure Monitoring System monitors the pressure of the 4 tires while driving.
If wheel positions on vehicle are changed or wheels or wheel sensors replaced, this must be confirmed using the steering column or the control module in the center console. Finally, the system has to relearn the wheel sensors.
Note. When changing wheels with wheel electronics (summer/winter tires), pressure must be checked and control module must relearn wheel electronics.
A fault may be saved in the DTC memory if
Less than three wheels with wheel electronics are installed.

Front axle toe-in curve, adjusting
Explanation
When the wheel compresses or rebounds, the wheel s toe changes as a function of the compression and rebound travel. The resulting toe measurements are described as the toe curve.
The change in the toe constants "S" is adjusted when the vehicle is raised by vertically shifting the tie rod end --> Toe constant "S" , adjusting
The wheel alignment computer determines the toe constant "S" using values measured in the initial and raised positions. The computer compares the measured values with the specifications and displays them on the screen.
Depending on the suspension, various adapters are necessary for raising the vehicle --> Application of adapters to suspension for measurement .
Note. An incorrectly adjusting toe constant causes vehicle to turn when braking/accelerating or when driving over bumps.
Vehicle, bringing into initial position for measurement
Note. Due to differing measuring lifts, it may be necessary to raise vehicle at front axle in order to be able to insert the spacer unit V.A.G 1925. Bounce vehicle after lowering.

New replacement steering columns are secured with transportation protection.
This transport protection must be removed after installing steering column in vehicle.
If a used steering column is to be removed and reinstalled, an assembly aid is useful in preventing upper and lower part of steering column from separating when removing from steering gear. Use e.g. a cable tie or wire as an assembly aid.
If the upper and lower parts of the steering column are pulled too far apart or pushed too close together the splines separate.
It is possible that rattling noises are created later if the splines are not in their original installation position.
Steering column, checking for damage
Visual check
- Check whether parts of steering column indicate damage.
Functional check
- Check whether steering column can be turned without catching or difficulty of movement.
- Check that steering column can be adjusted for height and reach.
Scheme 300

When reconstruction a component of the steering system besides the steering gear (pump, hoses, etc. )
- Check hydraulic fluid level and top off if necessary.
- Briefly start engine (max. 2 sec.)
Pump must not draw in any air and steering wheel must not be turned under any circumstances.
Approx. 30 sec. wait between individual engine starts.
- Check hydraulic fluid level and top off if necessary.
- Repeat this process until oil level remains constant.
- Start engine and allow to run 2 - 3 minutes, do not turn steering wheel.
Any remaining air in steering system will dissipate by itself when driving over the next 10 to 20 km.
Steering system, checking for leaks
Note. Following installation operations and with no hydraulic fluid in the expansion tank, the steering system must be checked for leaks.
- Start engine.
- Turn steering wheel in both directions to full lock and hold briefly. This builds up the maximum possible pressure.
To avoid damage to pump, steering wheel must not be held at stop longer than 10 seconds during this test.
In this position, the following components must be checked for leaks.
- Seal ring for steering pinion at steering gear valve housing.
- All line connections
- Rack sealing rings
This test can only be performed with boots slid back.
- Open boot spring hose clamp and ear hose clamp.
- Slide boot back.
If fluid is visible in steering gear housing and/or in boots, steering gear must be replaced.
Vehicles with 4-cylinder engines, assembly overview
There is no provision for servicing the power steering pump. If there are customer complaints, the cause must be determined using a pressure and leak test. If a malfunction is present, the power steering pump must be replaced.
Note. If the fluid level in the reservoir is low, the steering system must be inspected for leaks. If there are leaks in the area of the line connections, the lines/connections must first be inspected for leaks, tightened as necessary and wiped dry. Pumps from service parts inventory do not contain fluid. They must be filled with hydraulic fluid before installation and turned by hand, otherwise pump noise or damage can result in operation.
