Hi there just a few lines regarding the 2002 A4 1.8T with engine code AVJ. After surfing the net to find a source for oem parts and ordering an oil filter which i thought was for my year and model of car (same p/n on all sites) i discovered it was the wrong part so i contacted my local dealer to be told theres is only one filter that should be used on this engine code AVJ Oil Filter part number 068 115 561F at a cost of £10.03 GBP.

 

Out here in the US we use these.

But that's with AEB, AWM, ATW, or AMB motor codes.
