Test Conditions

The transmission must not be emergency running
Move the vehicle onto a 4-column workshop hoist or over a work pit so it is completely level.
The parking brake button is pressed to activate the electro-mechanical parking brake.
Intake hose of an exhaust extracting system connected.
The A/C system and the heater are off.
Vehicle Diagnostic Tester is connected.
The ATF temperature must not be higher than 30 °C (86 °F) at the beginning of the test. If the temperature is higher, let the transmission cool down first.
Before starting the test the coolant circuit to the ATF cooler must be disconnected. In order to do this, clamp off one coolant hose to the ATF cooler.

NOTE:

Read the ATF temperature on the Vehicle Diagnostic Tester.

The ATF level will vary depending on 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 underfill the ATF if the level is checked when the temperature is too high.

Both overfilling and underfilling impair the function of the transmission.

Clamp off the Coolant Hose to the ATF Cooler.

Courtesy of \

-- Disconnect the coolant hoses -1 or 2- for the ATF cooler -3- using Hose Clamps - Up To 25 mm:3094 .

Determine the ATF Temperature

-- Connect the Vehicle Diagnostic Tester.

-- Switch the ignition on.

-- Select Guided Functions .

-- Select individual test button and select the following tree structure one after the other:

Drivetrain
0D6 - Transmission
01 - OBD-capable systems
02 - Transmission electronics
02 - Transmission electronics, functions
02 - Measured values

-- Select "transmission fluid temperature" from the list.

-- Check the ATF temperature.

Specified value: not higher than 30 °C (86 °F).

ATF Level, Checking and Correcting

NOTE:

The ATF level is checked at the ATF check and fill hole.

The ATF level is correct if a small amount of fluid drips out of the ATF check and fill hole (this is normal as the fluid expands as it heats up) at an ATF temperature up to 40 °C (104 °F).

Replace the plug for the ATF check and fill hole.

CAUTION:

Risk of damaging the transmission.

Only use the ATF available as a replacement part for the automatic transmission 0D6.
Using other fluids can cause malfunctions or transmission failure.
Note the allocation. Refer to the Electronic Parts Information.
The ATF filler adapter must be clean. Do not mix the ATF with any other ATF types.

-- Use the Oil Filler:VAS6262A to secure the fluid container as high up on the vehicle as possible. Refer to the Electronic Parts Information for the ATF specification.

CAUTION:

Risk of damaging the transmission.

Engine must not be started if only a small amount or no ATF is in the transmission after repair work or after significant ATF loss.
In this case, pre-fill. Refer to ATF, DRAINING AND FILLING .

-- Remove the center or rear noise insulation. Refer to OVERVIEW - NOISE INSULATION .

-- Start the engine in "P" position.

-- Switch off ESP.

-- To fill the torque converter hold the engine in "P" position for 30 seconds at 2000 RPM.

-- At idle speed with the brake pressed switch between "P" and "D/S" positions and hold each position for 10 seconds.

-- Move the selector lever into "P".

-- Run the engine at idle.

-- Place the Used Oil Collection and Extraction Unit:SMN372500 under the transmission.

WARNING:

Danger of eye injury.

Wear protective eyewear.

-- Remove the plug for the ATF check and fill hole -arrow B- and if necessary drain any excess ATF.

Courtesy of \

If the ATF starts to leak out of the ATF check and fill hole -arrow B- before it reaches 40 °C (104 °F), then the ATF level is OK.
If no ATF flows out of the ATF-check and fill opening before the ATF has reached 40° C (104 °F), then top off the ATF. Refer to ATF, Filling .

NOTE:

The ATF check and fill hole must be sealed off again before the ATF reaches 40 °C (104 °F).

-- Tighten the new plug for the ATF check and fill hole. The ATF level test is now completed.
