BMW X5 xDrive ProblemsCheck Engine Light with Code P30FF and Rattle from Engine
The BMW X5 xDrive35i turbo engine suffers from waste gate issues which become progressively worse with normal driving and especially with harsh driving conditions.
The turbocharger uses exhaust gas to create air pressure which is then forced into the engine. When there is no demand for power, the exhaust gases are released into the exhaust through a waste gate to prevent the turbo from speeding up.
“Waste gate rattle” or “Turbo rattle” is a result of excessive movement between the waste gate and the waste gate seat. This is a progressive issue with the following symptoms:
- Rattling at cold start
- Rattling upon deceleration
- Loss of power
- Check Engine Light Illumination
- Manufacturer Specific OBD trouble code P30FF
- Very poor engine performance and MPG
Adjustment of the waste gate actuator can solve the issue, but the issue will return. If adjustment does not correct the issue, the turbocharger waste gate must be rebuilt with new bushings, or the turbocharger must be replaced. BMW has replaced many turbocharger assemblies under warranty to correct this issue.
