2008 BMW 535xi Problems

Check Engine Light with Code P30FF and Rattle from Engine

Late model BMW 535xi 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 Positive Battery Cable Connection in the Trunk Can Overheat

The insulated connector for the positive battery cable may have been incorrectly attached to the trunk floor panel, which can lead to a loosening of the bolt connection. Loosening of the connection can cause an increase in electrical resistance and overheating of the cable connection, which could lead to a fire, even when the vehicle is not in use. As a precaution, owners are advised to park outside until the remedy has been completed. Dealers will secure the battery bolt cable connection as necessary to correct this concern.

 

Brake Vacuum Pump Leaks Oil

The brake system vacuum pump check valve can leak oil and contaminate the power brake booster. This can result in loss of power brake assist. Dealers will repair the vehicle as necessary free of charge to resolve concerns.

I've owned this 08 for about 5 months now. I get between 24 stop and go, and 35 mpg on highway. Plenty of power on command, with the handling never letting me down.
