Note The fastening points for securing the fastener to the camshaft have been modified. A new special tool has been introduced described as camshaft fastener -T10171 A-. The camshaft fastener -T10171- may remain in use if modified as described below.

–  Place the template -1- on the camshaft fastener -T10171- 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 the drill on both sides. –  Mark the tool description -T10171- with an -A-. Checking sequence –  Remove the cylinder 1 spark plug. To do so, use the -T10094 A-extractor and the -3122 B-spark plug spanner.

–  Screw the adapter for dial gauge-T10170- into spark plug hole as far as the stop. –  Insert the dial gauge -VAS 6079- with extension -T10170/1- as far as the stop and secure using locking 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.

–  Disconnect connector terminal -1- on the turbocharger divert valve -N249 -. –  Unhook the hoses -2- on the pressure hose and open the cable guide -3-.

–  Disconnect the connector terminal -2- on the supercharger pressure sensor -G31- using the intake air temperature sensor 2 -G299 -. –  Remove bolts -3-.

–  Press securing clips -1- outwards and pull pressure hose -2- upwards. –  Then disconnect the pressure hose -2- from the turbocharger.

–  Disconnect the coolant hoses on the coolant pipe -1- and unscrew the pipe on the camshaft casing and on the engine block from below. –  Unscrew the fastening bolts for the camshaft covers -2- and remove covers

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. Next, turn the crankshaft in the direction of engine rotation to TDC cylinder 1 . t  Permissible deviation from TDC cylinder 1: ± 0.01 mm

–  Fit the counterhold -T10171A- as far as possible into the openings of the camshaft. The locking pins -arrow 1- should fit in the openings -arrow 2-. The word „TOP“-arrow 3- should be legible from above. If the counterhold -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 counterhold -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.
