Hello i have an 640d and i have some fault codes that says Boost pressure actuator VNT. The car has bad boost up to ca 2500rpm and after that it goes like crazy.
I think it’s the electronic wastegate on the small turbo. Do someone know what it can be? The codes: 292200: boost pressure actuator (VNT): position sensor in the boost pressure actuator defective or undervoltage. 27B900: exhaust pressure upstream of the turbine, plausibility: difference between measured and calculated exhaust pressure to low. |
