ATF level, checking
WARNING: This page is about a different variant/trim than selected.
Test conditions
- Transmission not in emergency operating mode.
- Vehicle on a flat surface
- Selector lever in "P" , let engine run at idle.
- Air conditioning and heater switched off.
- Vehicle Diagnosis, Testing and Information System VAS 5051 connected, "Vehicle On Board Diagnosis" and vehicle system "02 - Transmission electronics" selected.
- ATF temperature must not be higher than 30°C at start of test, allow transmission to cool down if necessary.
NOTE:
- ATF temperature appears in the display of Vehicle Diagnosis, Testing and Information System VAS 5051.
- The ATF level will vary according to the temperature of the ATF.
- Checking ATF level at too low ATF temperature leads to overfilling.
- If the ATF level is checked when the ATF temperature is too high, this will result in under filling.
- Over and under filling lead to impaired functioning of transmission.
- Only use the ATF available as a replacement part for the planetary gearing in automatic transmission 09E. Other oils could cause malfunctions or damage to the transmission. Follow ATF specification for corresponding transmission codes .
Checking ATF temperature
Display on VAS 5051 :
- In selection - 1 - , select diagnostic function "08 - Read measured value block" or "011 - Measured values".
Display on VAS 5051 :
1 - Enter display group
- In button field - 2 - , enter "4" for "Display group 004" and confirm input by pressing Q button.
Display on VAS 5051 :
- Read off ATF temperature indicated in display field - 1 -.
Checking ATF level and topping off
NOTE:
- The ATF level is checked at ATF inspection plug.
- The ATF level is correct if a small amount of fluid drips out of the inspection hole (this is normal as the fluid expands as it heats up) at an ATF temperature between 35°C and 45°C (for hot countries 50°C).
CAUTION:
- Various types of ATF are available for this transmission.
- Only use the ATF available as a replacement part for the planetary gearing in automatic transmission 09E.
- Other oils can cause malfunctions or transmission failure.
- Fill reservoir of ATF filler tool V.A.G 1924 with ATF for automatic transmission 09E
- Secure reservoir of ATF filling system V.A.G 1924 as high as possible on vehicle.
- Start engine and allow it to run at idle.
- Remove bolts - 3 - and - 4 - and remove rear section of noise insulation.
- Place Used Oil Extraction and Collection Device V.A.G 1782 below transmission.
CAUTION:
Wear eye protection.
- When ATF temperature of 35°C is reached, remove ATF inspection plug - arrow B - and drain off any excess ATF.
If ATF drips from ATF inspection hole before ATF has reached 40°C, ATF level - arrow - is OK.
NOTE:
- The ATF inspection plug must be installed again before the ATF reaches a temperature of 45°C (for hot countries 50°C).
- Tighten ATF inspection plug with new seal - arrow - to 80 Nm. The ATF check is now completed.
If no ATF drips out of ATF inspection hole when temperature has reached 40°C:
Top off ATF
NOTE:
- The ATF inspection plug must be installed again before the ATF reaches a temperature of 45°C (for hot countries 50°C). Allow transmission to cool and check again.
- Guide filler hook of ATF filler tool V.A.G 1924 into an opening - arrow - of protective cap, while doing so do not push cap up and in.
- Add ATF using ATF filler tool V.A.G 1924 until ATF drips from inspection hole.
NOTE:
- If the ATF level is too high or too low it will adversely affect the operation of the transmission.
- Tighten ATF inspection plug with new seal - arrow - to 80 Nm. The ATF check is now completed.
