SUBJECT
Recall: Check VANOS Adjustment Unit
SITUATION
BMW has informed NHTSA of its intention to voluntarily recall approximately 156,137 MY 2010-12 vehicles in the US, equipped with inline 6-cylinder engines. In very rare cases the bolts holding the variable camshaft timing (VANOS) unit housing may become loose or, in extreme cases, break. If that happens, a "Check Engine" or "Service Engine Soon" lamp will illuminate and a check control message will be displayed. If the operation of the VANOS unit is compromised, the engine will operate with reduced engine power in "safe mode". If ignored, the problem can become progressively worse, eventually leading to no start conditions, stalling and engine damage.
Drivers of potentially affected vehicles may continue to drive their vehicles, however, if they observe a "Check Engine" or "Service Engine Soon" lamp and Check Control message warning, drivers should immediately contact their nearest authorized BMW center to arrange service. In the event of stalling, drivers should carefully move away from traffic and stop the vehicle in a safe location as soon as possible. They should contact BMW Roadside Assistance at 1-800-332-4269 to have the vehicle brought to the nearest authorized BMW center. They should not continue to drive their vehicle.
BMW NA will update this SI as soon as additional information is available. Please contact your field team with any questions or concerns.
