BMW is recalling some vehicles manufactured from 2010-2012. More than 156,000 vehicles equipped with in-line six-cylinder engines have aluminum bolts on their cam-timing system's housing that could break.
Vehicles involved include the following:
If the aluminum bolts break, the vehicle's check engine light will come on, and a check control message will be displayed on the dash. If operation of the cam-timing unit (called VANOS) is compromised, the engine will operate with reduced power in "safe mode" and could become noisy. If the problem is left uncorrected, performance will worsen, and could lead to no-start conditions, stalling or engine damage.
On affected vehicles, BMW will replace the VANOS unit's housing bolts. The repair takes approximately 4 hours, and will most likely require a full day at the dealer service bay.
