Hello friends.
that it differentiates exists between wastegate of 3b & ABY & ADU & AAN?

It is that I have obtained one wastegate of 3b, I have opened it and the spring is equal, single changes the regulation of the screw.

Somebody knows in that they are different?

3B and AAN is 034 145 705 B
ABY and ADU is 034 145 705 E
If that helps.
I think the only difference from the factory is the boost level adjustment, AFAIK the springs are the same.
3B = 0.6 bar.
ABY = 0.8 bar.

Then on the inside they are equal?
Single it changes the tared one of the spring ?
