ATF Level, Checking And Filling

WARNING: This page is about a different car, the 2015 Audi Q7, 2014 Audi Q7, 2013 Audi Q7, 2012 Audi Q7, and 2011 Audi Q7. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required

Used Oil Collection and Extraction UnitSMN372500
Oil FillerVAS6262A
If necessary, adapter for oil filling Oil Filler - Adapter 6VAS6262/6
Oil Filler - Adapter 2VAS6262/2
Original 1 liter ATF bottle; for the correct part number.
Protective eyewear
Acid-resistant safety gloves

Procedure

WARNING:

Danger of personal injury.

Wear protective eyewear.
Wear acid-resistant safety gloves.
Keep a safe distance away from the coolant fan when working near it because the fan can turn on by itself.

There is an accident risk if a gear is accidentally engaged while the engine is running!

Before working on a running engine, move the selector lever into "P" and pull the parking brake button in order to set the electro-mechanical parking brake.

-- Measure the length of the bleed pipe on the Oil FillerVAS6262A. Shorten it if necessary. Refer to GENERAL INFORMATION .

Test Conditions

The transmission must not be in the emergency running.
The vehicle must be horizontal.
Selector lever in "P" and engine at idle.
The A/C and the heater are off.
At the start of the testing, the ATF temperature must not be higher than 30 °C (86 °F); let the transmission cool down.

NOTE:

The Vehicle Diagnostic Tester reads the temperature of the ATF.

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.

Only use the ATF available as a replacement part for the planetary gear in 8-speed automatic transmission 0C8. Other oils could cause malfunctions or damage to the transmission. ATF specification for corresponding engines. Refer to CAPACITIES .

CAUTION:

Do not start the engine or tow the vehicle if there is no ATF in the transmission.
Too little or too much ATF will impair the transmission.
Perform this check twice if the ATF circuit to the cooler was opened during a repair. Important: The ATF must be at least 80 °C (176 °F) after the first check. Perform a road test with tester. Check the ATF level after it has cooled down as described.

Check the ATF Temperature.

ATF Level, Checking and Correcting

NOTE:

The ATF level is checked at the ATF check hole.

The ATF level is correct if a small amount of fluid drips out of the check hole (this is normal because the fluid expands as it heats up) between 35 ° and 45 °C (95 ° and 113 °F) (for hot countries 50 °C (122 °F)).

-- Drive the vehicle onto a 4-column hoist or over a service pit so that it is absolutely level.

-- Remove the rear noise insulation -2-. Refer to NOISE INSULATION, REMOVING AND INSTALLING .

-- Start the engine and let it run in idle.

-- With engine idling depress the brake pedal and shift the selector lever through all the selector lever positions leaving the selector lever at least 10 seconds in each position.

-- Place the Used Oil Collection And Extraction UnitSMN372500 under the transmission.

Test Temperature 35 ° to 45 °C (95 ° to 113 °F)

-- Remove the plug -1- in the ATF pan for checking the ATF level.

ATF flows out of the overflow pipe.

NOTE:

Even if the level of oil is too low, first a small amount will flow out of the overflow tubes, because it fills during operation.

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

If ATF leaks from ATF check hole before temperature has reached 40 °C (104 °F), ATF level arrow is OK.

If no ATF drips out of the ATF check hole before 40 °C (104 °F) is reached, then the ATF level is not OK. Fill the ATF. Refer to ATF LEVEL, CHECKING AND FILLING .

If ATF is OK:

-- Replace the check plug gasket -arrow-.

-- Tighten the ATF check plug -1- with a new gasket, tightening specification. Refer to ATF LEVEL, CHECKING AND FILLING .

The ATF level test is now completed.

-- Turn off the engine.

-- Install the rear noise insulation. Refer to NOISE INSULATION, REMOVING AND INSTALLING .

CAUTION:

The Oil FillerVAS6262A must be clean and the ATF must not be mixed with another fluid!

-- Shake before opening.

-- Attach the ATF container to the Oil FillerVAS6262A.

NOTE:

Use adapter for oil filling Oil FillerVAS6262A if the thread on the container does not fit Oil Filler - Adapter 6VAS6262/6.

-- Let the ATF run into the transmission.

Check the ATF Level Several Time, if Necessary:

-- Disconnect the quick-release coupling on the Oil FillerVAS6262A.

ATF flows out of the overflow pipe.

If ATF leaks from ATF check hole before temperature has reached 40 °C (104 °F), ATF level arrow is OK.

If no ATF drips out of the ATF check hole before the ATF reaches 40 °C (104 °F), then fill and check the ATF until the level is OK.

If ATF is OK:

-- Let any excess ATF run out.

The ATF level is OK if it not possible to add more ATF.

NOTE:

Drained ATF may not be used again. Dispose of drained ATF properly.

-- Replace the check plug gasket -arrow-.
