ATF, Checking Level and Correcting
ATF, Checking Level and Correcting
Special tools, testers and auxiliary items required
• Vehicle Diagnostic Tester
• Oil Collecting and Extracting Device (V.A.G 1782)
• ATF Filler System F/CVT Transmission (VAS 5162)
• Protective goggles
Preparing:
• The illustration on the reservoir for (VAS 5162) is in the upper left graphic, it 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:
There is a 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, a preliminary filling with 5.5 to 7 liters ATF must be performed.
• Depending on the version, ATF inspection plugs - A - of different lengths are installed. The ATF check plug must be replaced according to the ATF test level. Always pay attention to the allocation according to the transmission code, refer to the Electronic Parts Catalog (ETKA). 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".
• Electro-mechanical parking brake is tightened.
• Exhaust hose/-hoses of an exhaust extraction system connected.
• The A/C and heating are turned off.
• Vehicle diagnosis tester is connected.
• The ATF temperature must not be higher than 30 °C (86 °F) at the beginning of the test. If necessary, let the transmission cool down.
• Read the ATF temperature on the vehicle diagnosis 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 diagnosis tester.
ATF, Checking Level and Correcting
• The ATF fill and check plug must be replaced.
- Select the following menu options under Functions/Component selection in "Guided Fault Finding" on the vehicle diagnosis tester:
• Drive
• 0AW transmission
• 01-On Board Diagnostic (OBD) capable systems
• 02-Transmission electronics
• 02-Transmission electronics, functions
• 02-Measured values
- Select transmission fluid temperature from the list.
- Check the ATF temperature.
There is a risk of damaging the transmission.
• For the correct ATF allocation, refer to the Electronic Parts Catalog (ETKA). Only the ATF available for the replacement part for the "Multitronic 0AW FWD" can be used for the "Multitronic 0AW FWD" transmission.
• Mixing the ATF, even in minimal amounts, is not allowed. The result would be transmission malfunction or failure.
• The ATF filler tool must be clean and the ATF must not be mixed with any other oils.
- Fill the (VAS 5162) reservoir with the ATF for the "Multitronic 0AW FWD"; ATF specification, refer to the Electronic Parts Catalog (ETKA).
• The shut-off valve on the (VAS 5162) must be closed.
- Remove the O-ring - 1 - on the connection - 2 - on the (VAS 5162).
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.
• 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 2 seconds.
• 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 (V.A.G 1782) under the transmission.
Danger of eye injury.
• Wear protective goggles.
- Remove the ATF check plug - A - when the ATF reaches 35 °C (95 °F).
• Approximately 5 to 10 cl of ATF will always drain initially from the internal oil level pipe when the plug is removed.
• Follow the disposal requirements.
- Install the (VAS 5162) connection, without the O-ring, all the way into the opening for the ATF inspection plug.
• By doing this, the oil level tube is pushed into the correct 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 -.
• Depending on the version, ATF inspection plugs of different lengths are installed. Always pay attention to the allocation according to the transmission codes, refer to the Electronic Parts Catalog (ETKA). To prevent damaging the transmission, compare the old and new ATF inspection plug.
• Tightening Specifications => [ (Item 1) ATF Fill and Inspection Plug ] ATF Level Checking, Draining and Filling Overview
• 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.
Filling ATF
• Engine continues running at idle.
- Turn the valve to the filler hose - lower arrow -. The ATF flows into the transmission.
- Turn the valve in the direction flow - down arrow - and check the ATF level.
• Approximately 5 to 10 cl of ATF will initially drain from the internal oil level pipe. This is normal.
- If no ATF leaks out, then turn the valve back toward the filler hose and let more ATF flow in. Check the ATF level again.
At 35 °C (95 °F) the ATF must flow out steadily and at first strongly, if necessary repeat the filling procedure.
- Wait until just a little ATF is coming out.
- After reaching the correct ATF level, remove the (VAS 5162) connection again.
• After removing the connection, the ATF will flow again.
- Tighten the new ATF check plug - A -.
• Depending on the version, ATF inspection plugs of different lengths are installed. Always pay attention to the allocation according to the transmission codes, refer to the Electronic Parts Catalog (ETKA). To prevent damaging the transmission, compare the old and new ATF inspection plug.
