hi, I resume the post because maybe someone has discovered something more
I have a polo 9n3 1.4 tdi pd80 (engine code BNV) and I am making various modifications to the monoblock, this leads me to mount 550cc injectors and firad + 80% tips
now my question is: I have the 038 130 073 BN injectors as standard, since the car is euro 4, unlike the usual 073 AL I bought 038 130 073 BJ (derivation seat ibiza 6l cupra euro 4 engine code BUK). ... will it work fine in the end? (p.s I am also installing 1.9 arl or buk pistons which exploded tell me are the same)
