Special tools and workshop equipment required

t	Locking pin -T10060 A-

t	Counterhold tool -T10355-

t	attachment tool -T10352/1-

t	Locking pin -T40011-

t	Torque wrench -V.A.G 1331-

Removing: –  Remove timing chain cover (top) → Chapter.

–  Turn vibration damper to „TDC“ position -arrow- using counterhold tool -T10355-. l  Notch on vibration damper must align with arrow marking on cover for timing chains (bottom). l  The markings -1- on the camshafts must face upwards. –  Remove timing chain cover (bottom) → Chapter.

–  Remove timing valve by turning assembly tool -T10352/1- in direction of -arrow-.   Caution The control valve has a left hand side thread.

–  Remove bolts -arrows- and detach bearing saddle.

–  Press oil pump chain tensioner in direction of -arrow- and lock in place using locking pin -T40011-. –  Remove oil pump chain tensioner -1-. –  Remove oil pump chain. To enable the chain tensioner to be slackened, the locking element in the chain tensioner must be raised. To do this, grind a 2nd  locking pin -T40011- to make the end pointed. A screwdriver with a blade width of approx. 1.5 mm can also be used.   Caution Risk of damaging the chain tensioner! Proceed with great care.

–  Use suitable tool to lift locking element of chain tensioner in direction of -arrow 1-, press tensioning rail for timing chain in direction of -arrow 2- and secure with locking pin -T40011-.

–  Remove tensioning rail for timing chain -2-.   Note Inlet camshaft will move in direction of engine rotation. –  Remove timing chain. Installing: l  Tightening torque → Chapter l  Guide rail for camshaft timing chain is installed. l  Chain tensioner for tensioning rail is installed   Note t  The following procedure must be performed in one operation; this requires the assistance of a second mechanic. t  The timing chain links with coloured markings must be positioned at the markings on the chain sprockets. t  Continue to hold inlet camshaft until tensioning rail is installed.

–  Check TDC position of crankshaft.

–  Fit timing chain onto exhaust camshaft. –  Fit timing chain onto crankshaft. –  Use spanner to turn inlet camshaft in direction of -arrow- and fit timing chain. »Hold« the inlet camshaft in this position.

–  Fit tensioning rail for timing chain and tighten bolt -2-. –  Pull locking pin -T40011- out of chain tensioner.

–  Attach bearing saddle and screw in bolts -arrows- hand-tight. –  Tighten bolts -arrows- for bearing saddle → Chapter. Further assembly is basically the reverse of the dismantling sequence.
