AS00.40-Z-0001-01A

 Warning

Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running.

Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts.

AS00.00-Z-0005-01A

 Warning

Risk of burn injuries, suffocation and poisoning when working on the exhaust system and the components connected to it. Risk of suffocation and risk of poisoning caused by inhalation of gaseous and solid components of the exhaust. Risk of poisoning caused by skin contact with solid components of the exhaust.

Wear protective clothing and safety glasses. Use the extraction system. Move people out of the hazard area.

Preparatory tasks

1

Remove engine air intake duct (1) upstream of air filter.

2

Remove bottom engine compartment paneling.

AR61.20-P-1105MFA

3

Check transmission for leak tightness and external damage.

If a leakage or external damage has been discovered,



determine and eliminate cause.

4

Carry out an oil change.

If an oil change is required.



5

Connect vehicle diagnosis system, read out fault memory and clear if necessary.



AD00.00-P-2000-06MFA

6

Operate parking brake and start engine.


The transmission must be filled with transmission oil before starting the engine.
Otherwise the transmission may be damaged.



Check

7

Carry out commissioning of dual-clutch transmission fully integrated transmission control electrohydraulic controller unit (Y3/14) with vehicle diagnosis system.



AD00.00-P-2000-06MFA

 Conduct "Rev up" and "purge" subitems.

8

Warm up engine at idle speed in neutral position.


Throughout the entire test, the parking brake must not be released, there must be no blip to the throttle, and no other disturbance variables may be generated that are not required for the work procedure.
Otherwise, these factors lead to the measurement being aborted and a restart of the measurement being required.

 The transmission oil level can be checked at a transmission oil temperature of 40 °C/104 °F or 70 °C/158 °F. A temperature tolerance of 2 °C or 3.6 °F is permissible for the measurement.

9

Call up "Check transmission oil level" function with vehicle diagnosis system.

 Before checking the oil level, the engine must be run for at least 2 minutes in idle speed.

 Run through the following steps in the vehicle diagnosis system:
Check transmission oil level 
Diagnosis 
Routine 
Start sensor/actor calibration 
Check transmission oil level A11 
Start function 
Run 

 In the instrument cluster, an "F" flashes during the oil level check.

10

Release and detach plug (93) from filler pipe (2).

11

Guide dipstick into filler pipe (2) of transmission, check oil level at idle speed and repeat procedure 3 times.


Use a lint-free cloth to wipe dipstick between measurements.
Measurement errors occur otherwise.

12

Extract or refill transmission oil.

If the transmission oil level is too high or too low.

 There are 200 ml to 250 ml of transmission oil between the scale values on the dipstick (interval 5 mm). To increase the oil level in the transmission by 1 mm, add approx. 50 ml of new transmission oil.

 Use new transmission oil only.
Replace funnel filter before adding fluid.
