I have a golf mk3 1.9 tdi engine swapped in my car but I cannot seem to find the engine code. I have checked the engine for any emgravement and the timing belt cover but still nothing. So I searched the cylinder head code (028 103 373n) up and it seems it is for an AFN engine. Still I am confused if this information is correct or not. Does anybody have any idea where could I find the engine code?
