I experienced this on my F10 less than a year old with less than 20000 km on the car. I have taken my car to Ingress. 2 weeks complete with no indication that they are able to diagnose the issue. Initially they claimed it was the sensor, then the Vanos, then DME and the latest is trying to swap the turbo unit. This seems like a complete trial and error troubleshooting. They claim BMW Malaysia tech is with them. Has anyone experienced the same problem.
