Hi guys, Im hoping someone can help me out of a sticky predicament here. A family member has a 1998 audi A4 1.8 petrol which required a replacement engine. So I sourced one from a breakers after getting a print out from Audi for the type engine the car currently has. (ADR). I was sent what the breakers claim is an ADR engine but at least two mechanics says its not the same as the one currently in the car. There are no markings on the replacement engine that suggest its an ADR engine. Only parts number of head and block. Is it possible to find out from these if this is an ADR engine or not? Part numbers; 058 103 373 A And 058 103 021 E My problem is the breakers wont take it back if it is an ADR engine even if its different to the one in the car currently. The only way I can get them to take it back is if its not an ADR. Can someone please help?!!!
