No they are not all the same, and yours is probably the AEG




1. The AEG is the only engine in the MK4 2.0 lineup that still has the throttle-by-cable system. All later engines use the Drive-By-Wire system. Thus, EPC is not available for the AEG engine code.

2. The most interesting engine code seems to be BBW. It has different torque and hp curves and it has 3 (that's right, three) oxygen sensors! It is also the only one that does not have a secondary air pump
