Transmission Fluid, Checking And Filling: Notes

Special tools and workshop equipment required

Oil Collecting and Extracting Device V.A.G 1782
Adapter for Oil Filling VAS 6262 A
Vehicle tester
Protective eyewear
Acid-resistant protective gloves

Procedure

Tightening specifications, refer to TRANSMISSION OIL DRAIN PLUG, INSPECTION PLUG AND OVERFLOW TUBE OVERVIEW .

NOTE:

REPAIR INFORMATION .
CLEAN WORKING CONDITIONS .
Observe notes for direct-shift gearbox 02E, Disposal regulations for oils, refer to TRANSMISSION .

WARNING:

Always keep a safe distance away from the radiator fan whenever working on the cooling system - danger of injury!
Fan can switch on by itself.
Wear protective eyewear.
Wear protective gloves.

CAUTION:

Do not start the engine if there is little or no oil in the transmission due to repair work or severe loss of transmission fluid.
In this case, first fill with DSG transmission fluid for direct manual transmissions.
Only transmission fluid for direct shift transmission available as replacement part must be used in the direct shift transmission 02E. Using other oils can lead to function problems or can even cause the transmission to fail.

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.
Place selector lever in position P, engage parking brake.
Exhaust hose/-hoses of an exhaust extraction system connected.
Engine running at idle.
The A/C and the heater are off.
Vehicle diagnosis tester connected, select Vehicle Self-Diagnosis and 02 - Transmission Electronics refer to Vehicle Diagnosis Tester.
At the start of the testing, the transmission oil temperature must not be higher than 30 °C (86 °F); let the transmission cool down.

NOTE:

The Vehicle diagnosis tester reads the transmission oil temperature.
The transmission oil level changes with the gear oil temperature.
A transmission oil inspection with a transmission oil temperature that is too low will lead to over-filling.
A transmission oil inspection with a transmission oil temperature that is too hot will lead to insufficient filling.
Overfilling or underfilling will influence the function of the transmission.

Transmission Oil Level, Checking

All precautionary measures and test conditions must be followed.

-- Remove the noise insulation. Refer to Removal and Installation .

NOTE:

Depending on the version, different noise insulation may be installed.

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

-- Read transmission oil temperature in display field -1-.

-- Remove the check plug -B- when the transmission oil temperature reaches 35 °C (95 °F).

NOTE:

The inspection plug -B- is located next to the pendulum support.

First, the transmission oil will drip into the overflow tubes -arrow 2-.

NOTE:

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

-- Check to see if the overflow tubes are correctly screwed into the transmission, tighten if necessary.

NOTE:

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

-- Allow the excess transmission oil to drain.

The transmission oil level is correct if a small amount of fluid drips out with a transmission oil temperature between 35 °C (95 °F) and 45° (113 °F) (this is normal as the fluid expands as it heats up).

In this case, no more transmission fluid must be added; the fluid level is OK.

NOTE:

Every 30 seconds, a small wave of fluid exits the oil level 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.

The transmission oil drained may not be used again. Dispose of drained oil properly.

If no oil leaks with a transmission oil temperature between 35 °C (95 °F) and 45° (113 °F), add more transmission oil Transmission Fluid, Filling .

Continuation for Correct Transmission Fluid Level:

-- Replace seal -arrow- for inspection plug.
