Gear oil level in front final drive, checking

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2009 Audi A4, 2008 Audi A4, 2007 Audi A4, 2006 Audi A4, and 2005 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The specified oil level must be maintained exactly; the transmission reacts very sensitively to over-filling.

Test sequence

Take vehicle for a short test drive to heat gear oil to approx. 60°C.
Move vehicle onto a lifting platform or over a work pit so that it is absolutely level.
Switch off engine and allow 5 minutes for gear oil to settle back into transmission case.
