Sounds to me like your charge air pressure sensor is likely covered in oil. I've had this with VWs. Haven't seen it with a bmw yet. It's extremely common for turbos to blow oil into the intake.

Isit easy fix? Costly GS?

Bottom line is, you should have a qualified technician diagnose it. If it was a charge air sensor on a VW, the fix is quite easy but the part is costly. My response above is a guess at best.
