I have a 2009 A4 2.0 TFSI with a CDNC engine code and I had the unfortunate pleasure of having to put new pistons in it due to high oil consumption. I am a qualified mechanic and I have taken the engine apart and it is nearly back together again apart from I have a small plastic part which to all intents and purposes it looks something to do with oil but i have no recollection of removing it or where it should go. I found it in a box where I have kept and labelled a lot of the nuts and bolts and the odd part. I attach photos of the part.
Any help greatly appreciated.
