– Turn the intake camshaft in the direction of the arrow -1- using
the Adapter - T40266- until the Camshaft Lock - T40271/2-
-2- can be pushed out of the chain sprocket splines. Release
the camshaft.
– Remove the Camshaft Lock - Component 1 - T40271/1- and
Camshaft Lock - Component 2 - T40271/2- .
– Check the adjustment. The painted chain links -arrows- must
line up with the markings on the chain sprockets.
– Install the bolts -arrows- and tighten them. Tightening specifi‐
.
– Lubricate the holes -arrows- with engine oil.
Note
Adapter sleeve -1- is not present on every bearing bracket.
– Attach the bearing mount. Do not tilt it when doing this. Hand-
tighten the bolts -arrows-.
– Remove the Tensioner Locking Tool - T40267- .
– Tighten the bearing bracket bolts -item 5-
– Install the pilot valves -item 6-
– Let the engine turn a second time in the direction of engine
rotation.
Note
Due to the ratio, the painted chain links no longer match up after
the engine has been turned.
– Remove the turning over tool and install the lower timing chain
cover. Refer to
.
Note
Tighten the bolts -1 and 4- with an additional turn after installing
the vibration damper. The bolts must be removed again to install
the vibration damper.
– Install the vibration damper. Refer to
⇒ “1.4 Vibration Damper, Removing and Installing”, page 47
– Install the upper timing chain cover. Refer to
⇒ “2.2.1 Upper Timing Chain Cover, Removing and Installing”,
– Install the ribbed belt tensioning damper. Refer to
⇒ “1.3 Ribbed Belt Tensioner, Removing and Installing”, page
– Install the ribbed belt. Refer to
⇒ “1.2 Ribbed Belt, Removing and Installing”, page 46
.
The rest of the installation is performed in reverse order of re‐
moval, noting the following:
– After performing work on the chain drive the adaptation value
in the Engine Control Module (ECM) must be adapted. To do

Balance Shaft Drive Chain, Removing
and Installing
The procedure “Balance shaft drive chain removing and installing”
is in the “Camshaft timing chain removing and installing” proce‐
dure. Refer to
⇒ “3.3 Camshaft Timing Chain, Removing and Installing”,
.
3.5
Chain Length, Checking
Caution
This procedure contains mandatory replaceable parts. Refer
to component overview prior to starting procedure.
Mandatory Replacement Parts
♦ Plug - Lower Timing Chain Cover
Note
If due to complaints (for example noises) an elongated camshaft
timing chain is suspected, the chain length can be checked as
described as follows.
– Remove the plug -arrow-. The plugs must be replaced.
– Turn the vibration damper in direction of engine rotation until
the chain tensioner piston is maximally driven out in direction
of -arrow-.
– Count the visible piston threads.
Note
The visible threads are all of the threads that are located to the
right of the chain tensioner housing -arrow-.
♦ If six or fewer threads are visible: the camshaft timing chain
does not need to be replaced.
♦ If seven or more threads are visible: the camshaft timing chain
must be replaced. Refer to
⇒ “3.3 Camshaft Timing Chain, Removing and Installing”,
.
3.6
Valve Timing, Checking
Special tools and workshop equipment required
♦ Dial Gauge Set - VAS6341-
♦ Dial Gauge Adapter - T10170A-
– Remove timing chain upper cover. Refer to
⇒ “2.2.1 Upper Timing Chain Cover, Removing and Installing”,
.
– Remove the noise insulation. Refer to ⇒ Body Exterior; Rep.
