–  To turn the crankshaft, place the bushing, the crankshaft pulley -2- and the crankshaft bolt -3- in position and tighten the crankshaft bolt (use retention tool -3415-). –  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 -T10170/1- as far as it will go and tighten it 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. –  Next, turn the crankshaft 45° in the opposite direction to that of the engine rotation.

–  Push the tensioning rail -1- in the direction of the -arrow- and lock the piston with the locking bolt -T40011-.

–  Mark direction of rotation of timing chain -3- using coloured felt tip marker pen.   Note Camshaft adjuster centre bolt -2- has a left-hand thread. –  Remove bolts -2- and -4- and take out the variator -1- together with the distribution chain -3-. To lock, use the retention tool -T10172-. –  Install camshaft adjuster -1- again. –  Renew bolts -2- and -4-. Tighten bolt -2- to 40 Nm and bolt -4- to 50 Nm (use counterhold -T10172-).

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

–  Turn the intake and exhaust camshafts until the adjustment tool -T10171A- is able to fully enter the openings in the camshafts. Locking pins -arrows 1- must engage in holes -arrows 2-. Inscription „TOP“-arrow 3- must be readable from above.   Note Camshafts must not be pushed axially whilst turning.

–  For securing the camshaft fastener -T10171A-, screw an M6 screw -arrow- in the respective hole by hand (do not tighten).   Note Remember that there are different securing points for the camshaft fastener -T10171A-. –  Remove camshaft sprocket bolts. Always use the retention tool -T10172-.   Note The camshaft fastener -T10171A- must not be used as a retention tool. –  Remove one camshaft sprocket. –  Place timing chain over camshaft sprockets, observing chain direction of rotation, and install camshaft sprocket again. –  Tighten camshaft bolts until camshaft sprockets can still just be turned on camshafts. –  Tension the distribution chain by removing the retention tool -T40011-.

–  Turn the crankshaft in the direction of engine rotation to TDC cylinder 1 . Permissible deviation from TDC cylinder 1:  ±  0.01 mm.   Note 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 .

–  Unscrew plug -arrow- from crankcase. –  Tighten the securing screw -T10340- until the end point in the crankshaft sump. –  Tighten the securing screw -T10340- → Anchor.

Use the securing screw -T10340- to immobilise the crankshaft in the direction of operation of the engine.

–  Using the retention tool -T10172-, hold the camshaft sprockets -1- and -5- in this position and tighten the bolts -2- (left-threaded) to 40 Nm and -4- to 50 Nm.   Note Crankshaft must not move and timing chain -3- must remain tensioned on both sides when tightening camshaft bolts. –  Remove adjustment tool -T10171A-.

–  Undo the fastening bolt -T10340- of the crankshaft sump. –  Turn the crankshaft in the direction of engine by 2 rotations to TDC cylinder 1 . Permissible deviation from TDC cylinder 1:  ±  0.01 mm.

–  Fit the adjustment tool -T10171A- as far as possible into the openings of the camshaft. If the adjustment tool -T10171A- can not be inserted: –  Repeat adjustment. If the adjustment tool -T10171A- can be inserted:

–  Tighten the securing screw -T10340- until the end point in the crankshaft sump. –  Tighten the securing bolts securing bolts -T10340- to 30 Nm.

–  Remove the camshaft fastener -T10171A-, lock the camshaft sprockets using the counter holder -T10172- and tighten the screws -2- (left hand thread) and -4- using a spanner by 1/4 of a rotation (90°).   Note t  Camshaft adjuster centre bolt -2- has a left-hand thread. t  Camshaft sprockets must not move on camshaft whilst tightening. Install in reverse order to dismantling, noting the following:   Note The fastening screw -T10340- is left on the crankshaft sump until the crankshaft pulley is mounted. –  Install timing housing → Chapter. –  Install crankshaft pulley → Chapter. –  Poly-V belt: Installing → Chapter. –  Replace the seals of the camshaft covers and lubricate with oil before assembly.
