ATF, Draining
The illustration on the reservoir for the CVT Gearbox Filler System 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:
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.
- Do not let the engine run or tow the vehicle without ATF.
- In this case, a preliminary filling with 5.5 to 6 liters (5.8 to 6.3 qts) 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 . To prevent damaging the transmission, compare the old and new ATF inspection plug.
- The engine is off.
- 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.
-- Remove the rear noise insulation. Refer to NOISE INSULATION .
-- Place the Used Oil Collection and Extraction Unit SMN372500 under the transmission.
Danger of eye injury.
- Wear protective eyewear.
-- Remove the ATF check plug -A-.
-- Drain the ATF.
Follow all disposal regulations!
Depending on the version, different ATF inspection plugs and different oil level tubes may be installed. Always pay attention to the allocation according to the transmission codes .
Transmission with A Long, Bent Oil Level Tube
-- Pull the oil level tube -A- out of the ATF check hole using the T-Handle Hook 3438 and let the remaining ATF drain out.
Shown in the illustration from the side in sections.
- The oil level tube must be replaced.
-- Push the new oil level tube -A- into the ATF inspection opening -B-.
- Installed position: the large tab -1- on the ATF level tube must face the recess -2- on the ATF check hole.
Transmission with A Short, Straight Oil Level Tube
-- Pull the oil level tube -A- out of the ATF check hole using the T-Handle Hook 3438 and let the remaining ATF drain out.
Shown in the illustration from the side in sections.
- The oil level tube -A- must be replaced.
- The O-ring -1- must fit correctly inside the groove in the oil level tube.
-- Push the new oil level tube -A- by hand straight into the ATF inspection opening -B-.
The O-ring on the oil level tube -A- seals the oil level height tube -C-. Only this way can the ATF level be correctly adjusted.
Ignore T-Handle Hook 3438.
Fill the Transmission with ATF
The illustration on the reservoir for the CVT Gearbox Filler System 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:
Danger of causing damage to the transmission.
- For the correct allocation of the ATF. 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.
Before installing a replacement transmission, always clean out the ATF cooler and ATF pipes using compressed air (maximum 10 bar (145 psi)). Refer to AUTOMATIC TRANSMISSION FLUID LINES, CLEANING .
-- Fill the CVT Gearbox Filler System VAS5162 reservoir with the ATF for the "multitronic 0AW FWD" ; ATF specification.
-- Secure the filled container to the vehicle as high as possible.
- The shut-off valve on the CVT Gearbox Filler System VAS5162 must be closed.
-- Remove the O-ring -1- on the connection -2- on the CVT Gearbox Filler System VAS5162.
Danger of misfilling the transmission.
- The connection -2- must be mounted by hand all the way into the 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.
-- Install the CVT Gearbox Filler System VAS5162 connection, without the O-ring, all the way into the ATF check hole hand-tight.
This >>presses<< the oil level tube into the correction installation position.
-- Turn the valve to the filler hose -lower arrow-. The ATF flows into the transmission.
-- Fill at least 5.5 to 7 liters (5.8 to 7.4 qts) ATF into transmission.
-- Move the selector lever into "P".
Immediately after starting the engine, let it run at 2, 500 RPM.
- Running the engine at high speeds is necessary so that the ATF pump is bled after a transmission repair.
- If this is not done, the pump could get damaged because it was briefly operated without any ATF.
-- Start the engine.
-- Using the accelerator pedal, let the engine run briefly at 2, 500 RPM.
-- ATF level, checking and filling. Refer to ATF LEVEL, CHECKING .
Observe all notes and test requirements for "Checking ATF level and filling".
