The Pressurized Gearbox Oil Filler Kit VAS 6617 must be clean. Flush it with transmission fluid (MTF), if necessary. Do not mix other transmission fluids.
The transmission must be still for at least 15 minutes to make sure the oil settles internally.

-- If necessary, remove the rear noise insulation, refer to Noise Insulation .

NOTE:

Place a cloth over the tunnel crossmember to prevent transmission fluid (MTF) from getting into the cast pockets on the top.
