BMW 335xi ProblemsAdaptive Headlight Module
The adaptive headlight modules located under the headlights are positioned strange. BMW decided to locate these under the headlights themselves. Issue is, in rainy weather water accumulates and corrodes the terminals. These can be reset by turning the car off and starting the car again But, the issue will continue when it rains or damp conditions persist. Replace the modules id the solution.

Aluminum cylinder head bolts may break, most commonly in the front part of the engine. Our technicians tell us revised cylinder head bolts are available which should correct this concern.

BMW 335xi 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 front passenger seat contains a mat that determines the presence and size of a seat occupant. This input to the airbag controller helps to determine if and how forcefully the passenger airbag should deploy in the event of a crash. The detection mat can develop cracks and fail. If this were to occur, the airbag would not deploy as expected, increasing the risk of personal injury. Dealers will repair the occupant detection mat to eliminate the possibility it may crack. Additionally certain vehicles will receive and extended warranty on the front passenger seat occupant detection mat.
An incorrect crimp connector may have been installed on the side air bag and belt tensioner wiring. There may be insufficient contact in the wiring, creating high resistance. This condition may cause the side air bag and/or safety belt tensioner not to deploy if needed in a crash, which increases the risk of injury. Dealers will repair the vehicles free of charge. The recall began September 16, 2009.
