Note. It is not possible to move the selector lever out of P if the battery is disconnected or if it is discharged. The vehicle cannot be moved or towed. The shift lock solenoid -N110- will cancel out the lock when the emergency release is activated.

Procedure

Remove the front ashtray insert.

Pry out the cap inside the ashtray housing with a screwdriver -arrow-.

AUTOMATIC TRANSMISSION FLUID LINES, CLEANING

Special tools and workshop equipment required

  1. Used Oil Collecting and Extracting Device V.A.G 1782
  2. Hose diameter approximately 18 mm
  3. Compressed air gun, commercially available
  4. Protective eyewear

Procedure

Note. Automatic transmission clean working conditions, refer to CLEAN WORKING CONDITIONS .

Before installing a replacement transmission, always clean out the ATF cooler and ATF pipes using compressed air (maximum 10 bar).

Note. If extremely dirty ATF flows out when cleaning using compressed air, flush the ATF cooler and lines using clean ATF.

ATF, CHECKING LEVEL AND CORRECTING

Special tools and workshop equipment required

  1. Vehicle Diagnosis, Testing and Information System VAS 5051B
  2. Used Oil Collecting and Extracting Device V.A.G 1782
  3. ATF Filler Tool V.A.G 1924
  4. Protective eyewear

Test Conditions

  1. The transmission must not be in the emergency operating mode.
  2. Move the vehicle onto a 4-column workshop hoist or over a work pit so it is completely level.
  3. The selector level is in P.
  4. The parking brake button should be activated to close the electromechanical parking brake.
  5. Exhaust hose/-hoses of an exhaust extraction system connected.
  6. The A/C and the heater are off.
  7. The VAS 5051B is connected.
  8. The ATF temperature must not be higher than 30 °C (86 °F) at the beginning of the test. The transmission must cool down first if the temperature is higher.

Note. ATF temperature appears in the display of VAS 5051B. The ATF level will vary according to the temperature of the ATF. It is possible to overfill the ATF if the level is checked when the temperature is too low. It is possible to overfill the ATF if the level is checked when the temperature is too high. Overfilling or under filling will influence the function of the transmission.

Procedure

Select the following menu items on the VAS 5051B in the Function/component Selection in guided fault finding

  1. Drive
  2. 0B6-Transmission
  3. 01-On Board Diagnostic (OBD) Capable Systems
  4. 02-Transmission Electronics
  5. 02-Transmission Electronics, Functions
  6. 02-Read Measured Value Block

Select the measured value from the list Transmission Fluid Temperature on the VAS 5051B.

Check the ATF temperature.

ATF, Checking Level and Correcting

Note. The ATF level is checked at the ATF inspection plug. The ATF level is correct if a small amount of fluid drips out of the inspection opening (this is normal as the fluid expands as it heats up) at an ATF temperature between 35°C (95°F) and 45°C (113°F) (for hot countries 50°C (122°F)).

CAUTIONThere is a risk of damaging the transmission. Only use the ATF available as a replacement part for the automatic transmission 0B6. Other oils can cause malfunctions or transmission failure. For the correct allocation. The ATF filler tool must be clean and the ATF must not be mixed with any other ATF.

Fill the reservoir on the V.A.G 1924 with the ATF for the automatic transmission 0B6; for the correct ATF specification.

Scheme 364
