Oil change Audi A8 2003 - 2010

Here is the sump plug

Do not forget to have a suitably sized receiving tray in place

With an oil catchment tray in position, use a 10mm Allen key to carefully remove the sump plug. Fully drain the oil. When the sump has emptied, wipe clean the sump plug area with a paper towel

You may need to remove the undertray to access the sump plug. Release the 12 Phillips fixtures and 2 clips. The undertray is heavy and should be correctly supported when removing
