Note. Observe before disconnecting battery --> Note before disconnecting battery. .

Battery sealing plugs

1. On batteries with visible min and max markings, electrolyte level only needs to be checked visually.
2. Electrolyte level must be between min. and max. markings.
3. On batteries where the outer min. and max. markings are difficult to see or the visibility of the electrolyte level cannot be guaranteed due to the opaque battery housing, the sealing plugs must be removed. Then it is possible to check electrolyte level by a visual inspection of the battery interior.
4. The electrolyte level must meet the inner electrolyte level marking (plastic bar). This corresponds to the outer max. mark.

Note. If electrolyte level is too low, battery loses capacity (loses performance) because the cell plates dry out. If the cell plates are not covered by electrolyte, the plates and plate bridges start to corrode causing the function of the battery to diminish. After a while the battery does no longer function. The battery becomes useless.

Regarding battery load test

Because of the high load on the battery during this test (a high current flows) the battery voltage lowers.

If the battery is OK, the voltage only goes down to the minimum voltage specification.

If the battery is malfunctioning or only faintly charged, the battery voltage will drop rapidly to below the displayed minimum voltage.

After the test, this low voltage remains steady over a longer time before the voltage slowly increases.

Cooling system: Check freeze protection, add coolant, if necessary

Note. All new engines are filled with coolant additive G 12 Plus according to TL VW 774 F (purple color). G 12 Plus can be mixed with the previous coolant additives G 11 and G 12 (red). Ensure that the system is replenished only with G12 Plus (due to its positive properties). G 12 Plus is suitable as a filled-for-life filling for cast iron and all-aluminum engines and gives optimum protection against freezing, corrosion damage, scaling and over-heating. G 12 Plus increases the boiling point to 275 ° F (135 ° C) and ensures for a better heat dissipation. The coolant portion of the mixture must amount to at least 40% (freeze protection to -13 ° F [-25 ° C]) and should not exceed 60% (freeze protection to -40 ° F [-40 ° C]). Otherwise the freeze protection will be reduced and the cooling efficiency will be worsened. The freeze protection must be ensured to approximately -13 ° F (-25 ° C).

Checking freeze protection and adding coolant additive if necessary

Special tools, testers and auxiliary items required

Scheme 26

1. Refractometer T10007

Note. Read the bright/dark boundary to obtain an accurate reading for the following tests. Place a drop of water on the glass to improve the readability of the bright/dark boundary. The bright/dark boundary can be clearly recognized on the "WATERLINE". Check the concentration of the coolant additive using refractometer T10007 (operating instructions).

Scheme 27

The scale - 1 - of the refractometer is designed for coolant additives G 12; G12 Plus and G11.

Scale - 2 - refers only to coolant additive G 13. (previously L80)

Note. The freeze protection must be ensured to approximately -13 ° F [-25 ° C]. If for climatic reasons greater freeze protection is required, the amount of G 12 Plus can be increased, but only up to 60% (freeze protection to about -40 ° F [-40 ° C]), otherwise freeze protection and cooling effectiveness will be reduced. If freeze protection is insufficient, drain off required quantity shown in freeze protection table and add coolant additive G 12 Plus.

Note. Observe waste disposal regulations!

1. Check coolant additive concentration after test drive again.

Checking coolant level and adding coolant if necessary

1. Check coolant level in expansion tank with engine cold.

Scheme 28

1. Delivery inspection: Coolant level above the "MIN marking" - arrow -.
2. Inspection service: Coolant level above the "MIN marking" - arrow -.

1. If coolant is too low, add required amount according to mixture ratio.

Note. Determine cause of fluid loss which cannot be attributed to normal use and rectify (repair measure).

Mixture ratio

Note. Coolant additive G 12 Plus conforming to TL VW 774 F prevents freeze and corrosion damage, scaling, and raises the boiling point. For these reasons, the cooling system must be filled with radiator freeze and corrosion protection fluid all year round. Especially in countries with tropical climates or when vehicle is driven under heavy load, the coolant improves the engine reliability by its increased boiling point. The coolant concentration must not be reduced by adding water, even during the warmer season. The coolant additive ratio must be at least 40%.

1. Bounce front and rear of vehicle up and down several times to settle vehicle suspension.

Setting low beam alignment of drivers side headlight

1. Move Hella Universal Beamsetter IV VAS 5107 into position in front of the vehicle so it is aligned with the vehicle and Hella Universal Beamsetter IV VAS 5107 is 30 to 70cm (12 to 28 in.) from the drivers side headlight.
2. Switch headlights ON in low beam position.
3. Align Hella Universal Beamsetter IV VAS 5107 so it is centered on the headlight (align vertically then horizontally).

Note. Use the arrows on the Hella Universal Beamsetter IV VAS 5107 housing as a guide. You may want to use a straight edge or tape measure, because alignment must be within 3cm (1.2 in.) of the center of the headlight. Without moving the Hella Universal Beamsetter IV VAS 5107 , slide Broad-band sight toward center of vehicle (Broad-band sight can also be moved up and down for a better position).

Use Broad-band sight to make final alignment of Hella Universal Beamsetter IV VAS 5107 to vehicle by

1. Loosening hand-wheel that locks column in place.
2. Sighting down through the slit in the Broad-band sight and rotating Hella Universal Beamsetter IV VAS 5107 and column until two similar points on vehicle are aligned

Note. Try using corners of the headlight housings or two screws that are the same height and as far apart as possible on the vehicle. Carefully tighten hand wheel without changing Hella Universal Beamsetter IV VAS 5107 position. Set Inclination to 1.0 %. Set Hella Universal Beamsetter IV VAS 5107 "Scaled wheel" to the proper low beam inclination %. Adjust height (vertical) alignment first. Turn headlight height adjuster screw to align the upper edge of the flat portion of the beam with the center horizontal line of the grid on the Hella Universal Beamsetter IV VAS 5107 pattern screen.

Note. VOL is the correct beam pattern for both right and left headlights.

Scheme 91

1. Adjust lateral (horizontal) alignment of drivers side headlight so that the peak (highest point) of the headlight beam pattern aligns with the right edge of the target box of the grid on the pattern screen (it should match the VOL pattern shown on the Hella Universal Beamsetter IV VAS 5107 ).

Note. If the height alignment changed, readjust.

Checking drivers side headlight high beam alignment

1. Switch headlights ON in high beam position.
2. Realign Hella Universal Beamsetter IV VAS 5107 with the high beam headlight if necessary.

Scheme 92

1. Set Beamsetter "Scaled wheel" to 0%.
2. Cover low beam lamp (use hand or small piece of cardboard) and check that the "hot spot" of high beam pattern is centered on the square target box of the pattern screen.

Note. High beam pattern is built into the reflector design and cannot be adjusted separately.

If high beam pattern is way out of adjustment

1. Inspect for reflector damage.
2. Replace reflector if needed.

Note. Always align headlight in the low beam position.

Aligning fog lamp

1. Switch fog lamps ON.
2. Align Hella Universal Beamsetter IV VAS 5107 with fog lamp (make sure it is between 30 and 70cm from the fog lamp lens).

Scheme 93

1. Set Hella Universal Beamsetter IV VAS 5107 scaled wheel to 1.4%.

Adjust fog lamp so the top of the beam pattern aligns with the centerline of the target grid on the beam pattern screen.

Passengers side headlight, alignment

1. Move Hella Universal Beamsetter IV VAS 5107 to the passenger side of the vehicle and follow the same procedures to align the Hella Universal Beamsetter IV VAS 5107 to the headlamp.
2. Align headlight low beam, check high beam and align fog lamp.

Note. Make sure to reset the Hella Universal Beamsetter IV VAS 5107 "Scaled wheel" to the proper setting each time you change from low beam to high beam or to fog lamp. Ensure that headlights and vehicle body are clean and free of fingerprints.

Tow starting/towing

1. Attach tow rope or bar only at following eyes

Front towing eye

Scheme 104

1. Remove cover from right bumper.
2. Remove towing eye from vehicle tool kit compartment.
3. Screw in towing eye until stop and tighten eye with wheel bolt wrench.

Rear towing eye

Scheme 105

1. Remove cover from right bumper.
2. Remove towing eye from vehicle tool kit compartment.
3. Screw in towing eye until stop and tighten eye with wheel bolt wrench.

Remove towing eye after use and return to vehicle tool kit storage compartment. Towing eye must always be in vehicle.

Note. The tow-rope should be able to stretch to reduce the risk of damage to both vehicles. It is advisable to use synthetic fiber ropes or ropes of similar elastic material only. However, it is safer to use a tow-bar! Avoid excessive towing effort and do not jerk. During towing operations on unsurfaced roads there is always a danger that the attachment points will be overstressed and damaged. Vehicle towing should only be done if it is not possible to start the engine with the starting assist cable.

If the vehicle must ever tow or be towed, observe the following

1. Regulations concerning towing must be observed.
2. Both drivers must be familiar with the specifics of towing procedures. Inexperienced drivers should not attempt to tow start or tow.
3. When using a tow rope the driver of the towing vehicle must engage the clutch very gently when moving off and changing gear.
4. The driver of the vehicle being towed must ensure that the tow rope is always taut.

1. The emergency lights must be switched on both vehicles - unless local regulations differ.
2. The ignition must be switched on, so that the steering wheel is not locked and the turn signals, horn, windshield wipers, and windshield washer system can be operated.
3. Since the brake booster only works with the engine running, the brake pedal must be stepped on with substantially more force when the engine is switched off.
4. With the engine switched off, the power steering also does not work, increasing the amount of steering effort.

1. Without lubricants in the manual transmission and/or automatic transmissions the car may only be towed with raised drive wheels.

When towing vehicles with manual transmission, observe the following

1. Before tow starting, push in clutch pedal and hold, and select gear 2 or 3.
2. Switch ignition on.
3. When both vehicles are moving, release clutch pedal.
4. As soon as engine starts, depress clutch and move gear stick into neutral to avoid running into the towing vehicle.

Note. Vehicles with catalytic converter (gasoline engine only) must not be started when the catalytic converter is at operating temperature and pulling the vehicle over a longer distance of more than 50 m. Otherwise unburned fuel may pass into the catalytic converter and cause damage. Tow starting vehicles with an automatic transmission is for technical reasons not possible.

When towing vehicles with front wheel drive and automatic transmission, observe the following

1. Selector lever must be in the "N" position.
2. Do not tow vehicle faster than 50 km/h (30 mph).
3. Do not tow further than 50 km (30 miles).

For longer distances, the front end of the vehicle must be raised.

Reason: When the engine is not running the transmission oil pump is not working and the transmission is not adequately lubricated for high speeds or long distances.

Using a breakdown vehicle, the vehicle may only be towed suspended at the front.

Reason: If given a rear suspended tow, the drive shafts turn backward. This would cause the planetary gears in the automatic transmission to achieve such high RPM that the transmission would be heavily damaged within a very short time.

When towing vehicles with all wheel drive and manual transmission, also observe the following

1. Do not tow vehicle faster than 50 km/h (30 mph).
2. Do not tow further than 50 km (30 miles).

Using a breakdown vehicle the vehicle may be towed suspended at front or rear.

Note. If normal towing of the vehicle is not possible, the vehicle must be transported with a special transporter or trailer. This is also valid for distances greater than 50 km (30 miles).

When towing vehicles with all wheel drive and automatic transmission, also observe the following

1. Selector lever must be in the "N" position.
2. Do not tow vehicle faster than 50 km/h (30 mph).
3. Do not tow further than 50 km (30 miles).

The vehicle must not be towed by a tow truck with front or rear axle raised.

Note. If normal towing of the vehicle is not possible, the vehicle must be transported with a special transporter or trailer. This is also valid for distances greater than 50 km (30 miles).

Vehicle checks within inspection and service framework

For vehicle checks, we recommend interactive acceptance VAS 5000 and performance test stand V.A.G 1858.

Brake check

Information for checking brakes on front and all wheel drive vehicles is in the corresponding brake system repair manual.

Performance check

Perform performance check on performance test stand recommended by Audi. The corresponding correction factors for automatic transmissions and all wheel drive are provided in these test stands. Vehicles with all wheel drive may only be tested on a four-wheel performance test stand. The four-wheel performance test stand V.A.G 1858 has movable rollers in order to be able to test vehicles with different axle spacing.

Tachometer check

With the tachometer test, the vehicle wheels are driven. Vehicles with all wheel drive may only be tested on a four-wheel test stand.

Shock absorber check

Information on testing shock absorbers can be found in the suspension repair manual.
