Transmission Fluid Level, Checking

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2017 Audi S3, 2017 Audi A3 Quattro, 2016 Audi S3, 2016 Audi A3 Quattro, and 2016 Audi A3. However, it is still accessible from the selected car via links, so may be relevant.

-- Press the brake pedal and hold it down.

-- With brake pressed, shift through all selector lever positions "P, R, N, D/S" at idle, retaining each position for at least 3 seconds.

-- Place the :SMN372500 under the transmission.

-- When the transmission oil temperature reaches 35° C (95° F), remove the drain and check plug -A-.

The collected gear oil runs out of the overflow tube -arrow 2-.

NOTE:

Some transmission fluid always leaks out when opening the drain and check plug -arrow 1-, regardless of the transmission fluid level.

-- Check if the overflow tubes are secure on the transmission.

NOTE:

If the overflow tube is not correctly connected, the correct transmission oil level cannot be determined.

-- Allow the excess transmission oil to drain.

If some gear oil still leaks out at a temperature between 35 and 45 °C (95 to 113° F) (due to additional warming), gear oil level is OK.

NOTE:

Every 30 seconds, a small wave of fluid exits the overflow tube, regardless of the height of the oil level (Reason: Cooling oil impulse to clutch.) This wave does not mean there is excess fluid and does not indicate the fluid level.

Do not reuse transmission fluid that was drained.

-- If the transmission fluid level is OK, perform final measurements. Refer to TRANSMISSION FLUID LEVEL, CHECKING .
