1. Perform a vehicle test. If the vehicle already has faults stored for the VANOS or camshaft position,
perform the recommended test plans for the faults stored before checking the timing chain. A defective
component (VANOS actuator or solenoid) can affect the outcome of the timing chain check.
2. Perform the applicable test plan to measure the timing chain's elongation, using ISTA/D 3.47 or higher.

IMPORTANT - Before starting the engine for the first time, and after replacing the timing chains:
1. Fill the engine with the specified amount of engine oil.
2. Connect a battery charger to the vehicle.
3. Remove the electric fuel pump fuse. Refer to the applicable wiring diagram using the VIN of the
vehicle in ISTA/D.
4. Crank the engine for 10 seconds.
5. After 10 seconds have elapsed, stop the starter, and allow the starter to cool for 20 seconds.
6. Repeat steps 4 and 5 two additional times.
7. Reinstall the electric fuel pump fuse and start the engine. Verify proper engine operation.
Important: Repair Instruction 11 31 052 for "Replacing both timing chains \
PREMIUM" describes the "replacement" of the engine oil pan gasket (seal).
Failure to replace this gasket (seal) as outlined in the repair instruction can result in an
engine oil leak and an unnecessary return visit to your workshop. Also, using liquid
sealer to substitute the required replacement of this gasket (seal) on the engine is "not
a proper" repair.
A repair to correct engine oil leakage that results from not replacing the engine oil pan
gasket (seal) as required during a previous repair is not a Warranty issue.
