Start the engine and drain any excess fluid until the level has reached the overflow tube.

Special Tools And Workshop Equipment Required 

• Vehicle Diagnosis, Testing and Information System VAS 5051B, for example
• Oil Collecting and Extracting Device V.A.G 1782
• Adapter for Oil Filling VAS 6262 A

Requirements 

• The engine is off.
• The vehicle is level and all hoist supports are the same height.
• Noise insulation is removed if necessary
• The selector level is in the >>P<< position.
• The vehicle diagnosis, testing and information system is connected
• The transmission fluid should not be warmer than 45 °C (113 °F) when starting the procedure.

Procedure 

-- Follow the rules of cleanliness when working on the transmission.

-- Only use the transmission fluid for the Direct Shift Gearbox (DSG) available as a replacement part. Other fluids can cause malfunctions or transmission failure.

About 5 liters of fluid will drain.

-- Install the overflow tube and tighten it to 3 Nm.

-- Install the adapter for oil filling VAS 6262 A -A- into the adapter hole hand tight.

-- Shake the bottles before opening.
