Mine has developed lot's of other issues too. Started with running lean codes and sometimes bank2 misfire codes. Also icv jamming codes. When it was -27c in here Finland It was very hard to get it started. I had to keep it alive with throttle for a while to get it to idle. After it idled few minutes it dropped few cylinder's off and again it was bank2 misfire (4-5-6 cylinder). I have tracked down all intake leaks and fixed them. ICV and MAF are new. Changed another set of ultrasonic cleaned injectors. And no change. Long before these vanos was rebuild, new lifters and valve stem seals.


Since I bought MAF made by hella, I'm waiting a good used original to arrive tomorrow, so I can test if it's the culprit. Also some previous owner has changed throttle body to aftermarket Topran, which is chinese. Bought a used original and waiting it to arrive also.


Mine's at almost 165k miles but I have owned 20+ bmw's and never have had problem with coils, but I guess that's next step.
