2011 BMW 535i ProblemsCheck Engine Light with Code P30FF and Rattle from Engine
Late model BMW 535i turbo engines suffer 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.
The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps. These worn bushings should be replaced.

2011 BMW 535i RecallsAir Bags And Restraint Systems Do Not Operate Properly In An Accident
The sensor cluster unit (SCU), if previously replaced during a service visit, may not be able to accurately determine if activation of safety restraint components is necessary in an accident. This could prevent deployment of air bags and other restraint system devices in an accident. Dealers will replace the SCU free of charge to resolve the concern.
The in-tank fuel pump may have wire contacts that are not properly crimped, resulting in the wiring connector melting, fuel leakage and vehicle stalling. Dealers will replace the fuel pump module free of charge to resolve the concern.
The bolts that secure the housing for the variable camshaft timing adjustment unit can loosen over time and possibly break, causing engine damage and engine stalling. Dealers will replace the four bolts for both intake and exhaust timing units free of charge to resolve the concern.
