Assembly overview - valve gear  
Note  
Cylinder head and cylinder head cover must be renewed  
together.  
After installing camshafts wait for approx. 30 minutes before  
starting engine. The hydraulic compensation elements must  
settle (otherwise valves will strike pistons).  
After working on the valve gear, turn the engine carefully  
at least 2 rotations to ensure that none of the valves make  
contact when the starter is operated.  
Always renew gaskets and seals.  
After working on the chain drive, adapt learnt values in en‐  
gine control unit. To do this, switch on ignition, and select  
the following menu option on vehicle diagnostic tester:  
0001 - Engine electronics, functions  
0001 - Basic setting  
Timing chain length compensator, reset after re-  
newing chain
