Special tools, testers and auxiliary items required

• Camshaft bar (T10068 A)

Procedure

- Remove intake manifold

- Remove cylinder head cover => [ Cylinder Head Cover ] Service and Repair.

- Adjust crankshaft at vibration damper bolt in direction of engine rotation to "TDC" marking.





• Markings on vibration damper and sealing flange must align - arrow -.

• Camshaft bar (T10068 A) must engage in grooves on both camshafts at the same time.





• Due to the camshaft adjuster function, the camshaft grooves may not be perfectly horizontal. Therefore, turn camshaft back and forth slightly with an open end wrench - arrows - if necessary to insert the camshaft bar (T10068 A).





• If camshaft bar (T10068 A) does not engage, rotate crankshaft 1 rotation further in direction of engine rotation.

- Camshaft position, checking:
