2011 BMW 335i ProblemsCheck Engine Light and/or Lack of Power
The Check Engine Light may illuminate and/or a lack of power may be noted due to a failed high pressure fuel pump. BMW has released a service bulletin regarding this matter, the suggested repair is to replace the failed high pressure pump.
Late model BMW 335i 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.
Noticed when having difficulty starting the car, took it to dealer, they said it was the fuel pump.

2011 BMW 335i RecallsDriver's Frontal Air Bag Inflator Ruptures And Sprays Metal Fragments
The driver's frontal air bag inflator may deploy the air bag with excessive pressure, resulting in the inflator rupturing and causing metal debris to be sprayed onto vehicle occupants. Dealers will replace the driver's frontal air bag 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.
The vehicle battery is connected to the fuse box via a heavy duty cable. It has been determined that the cable connection at the fuse box can degrade over time, resulting in increased electrical resistance. This increased resistance can cause the connection point to overheat and break, resulting in a loss of electrical power and causing the engine to stall, increasing the risk of a crash. Dealers will replace the positive battery cable connector and secure it with an improved method to correct this concern.
