NOTE: RISK OF DAMAGE
Damage of the engine and installed parts.
Non-compliance with the instructions for mounting and disassembly may lead to damage to the engine and installed parts.

Comply with the regulations for the installation and disassembly.
Perform work with vehicle care.

Check the lock of intake and exhaust camshaft adjusters.
Position open-end spanner (1) on the hexagon head of the camshaft (2).
Move open-end spanner slightly back and forward in direction of arrow.
The camshafts must have a positive-type connection to the VANOS adjusters.
If no power transmission exists, the affected adjuster must be replaced.
Insert special tool 0 496 366 (11 8 570).
Slowly turn engine until the special tool 0 493 882 (11 9 190) can be slid into the groove on the crankcase .

Check
- Place the special tools 0 496 381 (11 9 893) flush onto the surface on the cylinder head.
- Determine the air gap with a feeler gage.
NOTE: TECHNICAL INFORMATION
If the check finds that the valve timings are incorrect, they must be adjusted.
For additional information, see: ADJUSTING CAMSHAFT TIMING ON LEFT SIDE , or ADJUSTING CAMSHAFT TIMING ON RIGHT SIDE .

A maximum measured value of 0.4 mm is permitted at the intake and exhaust camshaft to the intake side.
Result

» Air gap greater than 0.4 mm.

Measure
- Adjust valve timing.
Remove special tools 0 496 381 (11 9 893).
