Hi everyone!

My car: vw Polo 9N 2004, 1.4 TDI PD, 75 HP, engine code BAY

current state: needs new engine

problem: engine code BAY is hard to find and the ones which can be found are quite expensive

questions: can I replace this engine with one of a different code such as AMF(or other compatible, I am open to any sugestion) ?
will the original ECU of the car accept this other engine code?
same question for turbo and other parts as well
will the other engine fit mechanically with the exhaust, gearbox, etc? ( i've read that these 2 engine code ar identical from a mechanical perspective)

Thank you!

p.s. I do not make any reference to such thing as un upgrade of some sort, I just want to replace the original engine (code BAY) with an identical 75 HP engine with a diferent code. (eg. AMF )

Youll need a BAY or equivalent B series engine. The A series engines have different management and it wont play nicely as different sensors etc (and are much older)

Mechanically they are very similar.
