BMW is recalling 156,137 vehicles in the United States of America from the 2010-2012 model-years due to a potential defect with the variable camshaft timing.
BMW says the recall will address a problem with the variable camshaft timing, also known as VANOS, which could reduce engine power and further cause damage if not repaired.
A BMW spokesman said for Automotive News: “The unit rotates the intake or exhaust camshaft in order to alter the timing of the lift of the respective intake or exhaust valves.”
In a statement, BMW said that “in very rare cases, the bolts holding the variable camshaft timing unit housing may become loose or, in extreme cases, break.â€
Should that happen, the “check engine†or “service engine soon†light comes on followed by the display of a “check control message.â€
“If ignored, the problem can become progressively worse, eventually leading to no start conditions, stalling and engine damage,†BMW said.
