Hi guys, my 2001 build A6 2.7T has a CEL on and needs a bank 2 sensor 2 O2 sensor (passenger side rear). I understand that is the plug marked '195' which is black, up under the bonnet near the passenger side rear of the engine bay. Problem.. ordered an 'exact fit' o2 sensor online and the plugs are different. Below are the two different plugs, but all the sensors on Ebay show the same 'wrong' plug. What aren't I getting? (except a NYS inspection sticker!)
Thanks guys,

Paul
