ATF, Checking Level And Correcting

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Audi S5, 2014 Audi S5, 2013 Audi S5, 2012 Audi S5, and 2011 Audi S5. However, it is still accessible from the selected car via links, so may be relevant.

Special tools and workshop equipment required

Vehicle Diagnostic Tester
Oil Collecting and Extracting Device V.A.G 1782
ATF Filling Tool V.A.G 1924
Protective Goggles

Test Conditions

The transmission must not be in the emergency running
Move the 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.
Exhaust hose/-hoses of an exhaust extraction system connected.
The Air Conditioning (A/C) and the heater are off.
vehicle diagnostic tester is connected.
The ATF temperature must not be higher than 30 °C (86 °F) at the beginning of the test. Let the transmission cool down first, if necessary.

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.

ATF, Checking Level and Correcting

Tightening specifications, refer to Specifications

-- Select the following menu points from the vehicle diagnostic tester in the Functions/Component selection for the "Guided Fault Finding" :

Drive
0B5 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.

CAUTION:

There is a risk of damaging the transmission.

Only use replacement part ATF for the S-Tronic transmission 0B5.
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.

-- Fill the V.A.G 1924 with ATF for S-Tronic transmission; ATF specification,

-- Secure the reservoir of V.A.G 1924 as high as possible on vehicle.

CAUTION:

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, pre-filling is necessary, refer to ATF, DRAINING AND FILLING .

-- Remove the rear noise insulation -2-. Refer to "Underbody Trim" in EXTERIOR EQUIPMENT (CABRIOLET) .

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

-- While pressing the brake pedal and with the vehicle idling, shift through all the selector lever positions ("P", "R", "N", "D", "S" or "D/S") leaving each position engaged for at least 2 seconds.

-- Move the selector lever into "N".

-- Move the selector lever into "P".

-- Run the engine at idle.

NOTE:

The ATF level is checked at the ATF inspection plug.

ATF level is correct if a little bit of fluid still leaks out of the ATF inspection plug between 30 °C and 50 °C (86 °F and 122 °F) (dependent on the fluid level rising as the fluid warms up).

-- Place the V.A.G 1782 under the transmission.

WARNING:

Danger of eye injury.

Wear protective goggles.

-- When the ATF reaches 30 °C (86 °F), remove the ATF check plug -arrow- and drain off any excess ATF if necessary.

If ATF starts to leak out of the ATF inspection opening before it reaches 40 °C (104 °F), then the ATF level is OK.

NOTE:

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

-- Tighten the ATF inspection plug. The ATF level test is now completed.

-- Install the noise insulation. Refer to "Underbody Trim" in EXTERIOR EQUIPMENT (CABRIOLET) .

If no ATF drips out of the ATF inspection opening when the temperature has reached 40 °C (104 °F):

ATF, Filling

NOTE:

ATF inspection plug must be closed again at the latest at 50 °C (122 °F), if necessary, turn off the engine, let the transmission cool off and repeat test.

-- Engage the filler hook from the V.A.G 1924 into the ATF inspection opening.

-- Add ATF using V.A.G 1924 until ATF drips from the check hole.

NOTE:

Too little or too much ATF will impair the transmission.

-- Tighten the ATF check plug -arrow-. The ATF level test is now completed.
