Special tools and workshop equipment required

Vehicle Diagnostic Tester
Used Oil Collection and Extraction Unit SMN372500
Protective eyewear

CAUTION:

Danger of causing damage to the transmission.

Only use replacement part ATF for the S tronic transmission 0B5.
Pay attention to allocation.
Using other types of ATF can result in the malfunctions or transmission failure.
The ATF filler tool must be clean and the ATF must not be mixed with any other oils.

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.
Overfilling or underfilling will influence the function of the transmission.

Test Conditions

The transmission must not be in the emergency running
Move vehicle onto a four-pillar shop hoist or over a work pit so that it is absolutely horizontal.
The selector level is in "P".
The parking brake button should be activated to close the electro-mechanical parking brake.
Intake hose of an exhaust extraction system connected.
The Air Conditioning (A/C) and the heater are off.
Vehicle Diagnostic Tester is connected.
The ATF temperature should not be higher than approximately 30 °C (86 °F) at the beginning of the test, because during the test the ATF temperature will raise.

ATF Level, Checking

-- Select the following menu items in Functions/Component selection "Guided Fault Finding " on theVehicle Diagnostic Tester:

Drivetrain
0B5 - Transmission
01-OBD-Capable Systems
02-Transmission Electronics

02-Measured Values

-- Select Transmission Fluid Temperature from the list.

-- Check the ATF temperature.

CAUTION:

Danger of causing damage to 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-filling is necessary. Refer to ATF, DRAINING AND FILLING .

WARNING:

Danger of eye injury.

Wear protective eyewear.

-- When ATF temperature of 30 °C (86 °F) is reached, unscrew ATF inspection plug -arrow-.

ATF level is correct when at an ATF temperature between 30 °C and 50 °C (86 °F and 122 °F) a small amount of fluid drips out of the inspection hole. If this is not the case, add ATF. Refer to ATF, DRAINING AND FILLING .

NOTE:

ATF inspection opening must be closed again by 50 °C (122 °F) at the latest.

Tightening Specifications

Refer to

-- Tighten the ATF check plug, tightening specification: 45 Nm .
