2011 BMW 535i Problems

Check 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.

Loosness in the Front Suspension Due to Worn Tension Strut Bushings

The front thrust rod bushingsalso referred to as tension strut bushingsare 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 Recalls

Fuel Leaks And Vehicle Stalls From In Tank Fuel Pump Wiring 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.

Engine Timing Bolts May Loosen And Break

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.

Fuel Sensor

The fuel level sensor is the sensor located in the fuel tank that tells the vehicle how much fuel is in the fuel tank. This sensor has a float attached to it that may become wedged against the fuel tank, causing the float to be stuck in one spot instead of "floating" on top of the fuel in the tank. Because the float can not move, the instrument cluster will indicate that the fuel level is still full, even though it empty. Running the vehicle out of fuel will result in the vehicle shutting off (stalling) while driving down the road. BMW will replace the fuel level sensor free of charge. If you own a 2010 or 2011 5-series and did not receive a notice, contact BMW at 1-800-525-7417 or the national highway traffic Safety Administration at 1-888-327-4236 to verify this recall does not apply to your vehicle. You may need the Vehicle Identification Number (VIN), located on a placard attached to the vehicle's driver side door frame. Your vehicles production date is also on this placard.
