CAUSE
One or both (intake and/or exhaust) of the VANOS gear assemblies have failed; the attaching bolts may have also loosened and/or broken. PROCEDURE
Replace both VANOS gear assemblies. Refer to Repair Instruction 11 36 046, "Removing and installing or replacing intake and exhaust camshaft units."
If the bolts have been found broken, the missing portions of the bolts will need to be retrieved from the engine before the final repairs are made. This additional work may include removing the engine oil pan, and a close examination of the timing chain drive to retrieve the missing parts. Refer to the applicable repair instructions for oil pan removal procedures.
