A friend of mine blew his Audi A3's fuel distributor and he's trying to look for a new OEM part. Another friend of mine, who works on a warehouse, managed to get himself a list of the OEM part codes, however the codes vary according to the engine number. Thing is, he can't find the number on the engine. Where would that be located in a 2002ish 1.9 TDI engine? (The car's specific register date is October of 2002).
