Note The mounting points for securing the camshaft clamp were modified. A new special tool has been introduced described as camshaft fastener -T10171A-. The former camshaft fastener -T10171- used until now may still be used if it is modified according to the following description.

–  Place the template -1- on the camshaft fastener -T10171A- as shown in the figure. –  Mark the camshaft fastener -T10171- with a notch at the mark -2-. –  Drill the camshaft fastener -T10171- using a 7 mm drill bit. –  Deburr hole on both sides. –  For tool number -T10171-, add an -A-. Checking sequence –  Remove the cylinder 1 spark plug. To do so, use the extractor -T10094A- and the wrench -3122B- → Chapter.

–  Release connector -2- and pull off. –  Remove oil pressure switch -F1--1-.

–  Tighten the adjustment tool -T10170- as far as possible on the thread of the spark plug. –  Insert the gauge -VAS 6079- with the extension of the adapter for the gauge -T10170- as far as it will go and immobilise with the clamping nut -arrow-. –  Turn the crankshaft in the direction of engine rotation to TDC cylinder 1 . Observe the position of the small pointer of the gauge.

–  Remove the coolant hose from the hose clip -arrow-. –  Unscrew the securing screws and remove the sealing cover of the camshaft -1-.

The openings -arrows- of the camshafts should be in the positions shown. Where necessary, turn the crankshaft one turn (360°).   Note t  When the crankshaft rotates more than 0.01 mm beyond the TDC, the crankshaft must be rotated by approx. 45° against the direction of the engine again. Then turn crankshaft in direction of engine rotation to TDC No. 1 cylinder. t  Permissible deviation from TDC cylinder 1: ± 0.01 mm

–  Fit the adjustment tool -T10171A- as far as possible into the openings of the camshaft. Locking pins -arrows 1- must engage in holes -arrows 2-. Inscription „TOP“-arrow 3- must be readable from above. If the adjustment tool -T10171A- can not be fitted to the end in the openings in the camshaft, the distribution timing is incorrect and should be adjusted → Chapter. If the adjustment tool -T10171A- can be fitted to the end in the openings in the camshaft, the distribution timing is correct. Install in reverse order to dismantling, noting the following: t  Replace the seals of the camshaft covers and lubricate with oil before assembly. Specified torque .
