ok i am joking.It was easier that i was thinking.I called bosch dealer in greece and i find a bmw enthusiastic who know very good bmw ecu.And also he find me and he sent me the drawing.I will go there to thank him.He told me that it is common problem when you have icv bad.Some chips and resistans must be changed and he promised me that it will be better than new.

OK that's great news.

Something else... the past weekend I was working on a 320i (nope, no 'S') that also had ICV problems.

Motronic switches most things with the mass/ground/negative wire, like the injectors but the ICV as well. We found out that the negative wire had a short (probably due to tear or wear) to the chassis (somewhere?!) so the ICV never stopped! We replaced the wire between Motronic and ICV and it's all fine now!
