PROCEDURE
1. Replace both VANOS gear assemblies. Refer to Repair Instruction 11 36 046, “Removing and installing or
replacing intake and exhaust camshaft units.”
2. 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.
IMPORTANT!
Replacement of the VANOS gear assemblies described in this bulletin does not require TeileClearing
authorization if the model and production of the vehicle are listed above and the vehicle has the condition
described in this document.
Vehicles that are not within this production period and/or do not have the condition described in this
bulletin require TeileClearing authorization when replacing the VANOS gear assemblies.
