2006 BMW 330xi ProblemsBurning Smell or Oil Drips on the Ground Due to Engine Oil Leak
Valve cover gasket leaks are common after 60,000 miles. Symptoms will include oil drips under the vehicle and burning oil smell from the engine compartment.
After 60,000 miles, the front outer half-shaft boots tend to tear and leak grease. In most cases, only the boot will have to be replaced; however, if it is not repaired soon enough, the half-shaft may need to be replaced. The front outer boots are put under heavy stress because of their involvement with the suspension when making turns.
An engine coolant leak may develop from the expansion tank resulting in engine overheating. When a cooling system component fails the entire cooling system should be inspected. It is not uncommon to find additional component have failed or are leaking.
Overheating can cause severe engine damage. If the engine begins to overheat it is recommended to stop at the first available location and have your vehicle towed to a repair shop.

2006 BMW 330xi 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.
On 25 vehicles, the bolt securing the front control arm and swivel bearing were not tightened to specification and could loosen over time. If the nuts loosen, vehicle handling and control could be compromised, increasing the risk of a crash. Dealers will tighten the front control arm and swivel bearing connection to the correct specifications. The recall began November 21, 2006.
