NOTE:

The illustration on the reservoir for the :VAS5162 in the upper left graphic refers to the use of special ATF for CVT transmissions.

In addition, the necessary work steps for filling are illustrated, which are described as follows:

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, a preliminary filling with 5.5 to 7 liters ATF must be performed.

Depending on the version, ATF inspection plugs of different lengths -A- are installed. The ATF check plug must be replaced after the ATF level test. Always pay attention to the allocation according to the transmission codes in the Parts Information. To prevent damaging the transmission, compare the old and new ATF inspection plug.

Test Conditions

The transmission must not be in the emergency running
Move the vehicle onto a 4-column shop hoist or over a work pit so it is completely level.
The selector level is in "P".
The electro-mechanical parking brake is set.
Exhaust hose/hoses of an exhaust extraction system connected.
The Air Conditioning (A/C) and the heater must be off.
Vehicle Diagnostic Tester is connected.
At the start of the testing, the ATF temperature must not be higher than 30 °C (86 °F); let the transmission cool down.

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.

Read the ATF temperature on the Vehicle Diagnostic Tester.

ATF Level, Checking and Correcting

NOTE:

The ATF filling and check plugs must be replaced.

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

Drivetrain
0AW 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.

CAUTION:

Danger Of Causing Damage To The Transmission.

For the correct allocation of the ATF. Refer to the Parts Information. Only use replacement part ATF for "multitronic 0AW FWD" for the "multitronic 0AW FWD" transmission.
Do not mix other ATF types, even in small quantities. Malfunctions and transmission failure could occur.
The ATF filler tool must be clean and the ATF must not be mixed with any other oils.

-- Fill the :VAS5162 reservoir with the ATF for the "multitronic 0AW FWD" ; ATF specification. Refer to Parts Information.

-- Secure the ATF filler system reservoir as high as possible on the vehicle.

The shut-off valve on the :VAS5162 must be closed.

-- Remove the O-ring -1- on the connection -2- on the :VAS5162 .

CAUTION:

Danger of misfilling the transmission.

The connection -2- must be mounted by hand all the way into the ATF inspection plug hole on the transmission without the O-ring.
The oil level tube can be pushed into the ATF inspection plug hole in the upper position only when the O-ring is not on the connection -2-.
This is the only way to correctly check and/or adjust the ATF level to maximum.

-- Remove the rear noise insulation. Refer to NOISE INSULATION, REMOVING AND INSTALLING / OVERVIEW - NOISE INSULATION .

NOTE:

Immediately after starting the engine, let it run at 2, 500 RPM.

Running the engine at high speeds is necessary to bleed the ATF pump.

If running at high speeds is not performed, the ATF level cannot be adjusted correctly.

-- Start the engine with the selector lever in "P".

-- Using the accelerator pedal, let the engine run briefly at 2, 500 RPM.

-- Press the brake and move the selector lever alternately between "R" and "D" and let the engine idle for approximately 2 seconds in each position.

-- Perform the procedure 3 times

-- Press the brake pedal and move the selector lever through all the gears ("P", "R", "N", "D", S). Leave the selector lever in each gear approximately two seconds.

NOTE:

The ATF level is checked at the ATF inspection plug.

ATF level is correct if a little bit of fluid still escapes at the ATF check plug between 35 ° and 45 °C (95 ° and 113 °F) (50 °C (122 °F) for hot countries) ATF temperature (dependent on the fluid level when warming up).

-- Place the :SMN372500 under the transmission.

WARNING:

Danger of eye injury.

Wear protective eyewear.

-- Remove the ATF check plug -A- when the ATF reaches 35 °C (95 °F).

NOTE:

Approximately 5 to 10 cl of ATF will always drain initially from the internal oil level pipe when the plug is unscrewed.

Follow the disposal requirements.

-- Install the :VAS5162 connection, without the O-ring, all the way into the opening for the ATF inspection plug.

NOTE:

This >>presses << the oil level tube into the correct upper installation position.

-- Turn the valve in the flow direction -down arrow- and check the ATF level.

At 35 °C (95 °F), the ATF must flow out continually and at first strongly.

-- Wait until just a little ATF is coming out.

-- Tighten the new ATF check plug -A-.

NOTE:

Depending on the version, ATF inspection plugs of different lengths are installed. Always pay attention to the allocation according to the transmission codes in the Parts Information. To prevent damaging the transmission, compare the old and new ATF inspection plug.

Tightening specification: Refer to -item ) TRANSMISSION DRAIN AND INSPECTION PLUG OVERVIEW - ATF FILL AND CHECK PLUG

NOTE:

The ATF check plug must be installed again before the ATF reaches a temperature of 45 °C (113 °F) (50 °C (122 °F) with hot climates).

If the ATF gets warmer than 45 °C (113 °F), it will leak out and the transmission will not have enough ATF.

The ATF level test is now completed.

If, at 40 °C (104 °F), no ATF or just a few drops flow out, fill the ATF. Refer to ATF, FILLING .
