Checking

Rotate piston of cylinder 1 to ignition TDC position.
To do this, rotate crankshaft in direction of rotation of engine with wrench 001 589 65 09 00 until the TDC marking (arrow) on the vibration damper (8) is aligned with the TDC pointer (7) on the timing case cover.

The piston of cylinder 1 is in ignition TDC when the base circles of the righthand intake/ exhaust camshaft at cylinder 1 are resting against the bucket tappets (6).

Camshaft adjuster of intake camshafts against retard stop (mechanical stop in direction of rotation of camshaft).

The 4 mm holes (arrows) in the camshaft flanges are touching the top edge of the cylinder heads (arrows).
As a check, insert 4 mm dia. pins (111 589 03 15 00) into the holes (arrows) in the camshaft flanges at the left and right cylinder head.
