hello,

I have an audi a4 2.0tdi 16v.Having had many different problems with the engine I decided to change it.What I would like to ask you is whether there is another engine code that I could use in my car,except the BLB engine I already use,without problems arise in electrical and other systems.Your help is going to be very useful because this car is rare in my country so there aren't specialized engineers.

thanks in advance
