TECHNICAL INFORMATION
Clean spark plug slot with compressed air.
The spark plug shafts must be cleaned using compressed air after having removed the ignition coils and before removing the spark plugs. After removing the spark plugs, check the sealing surface again for dirt contamination and if necessary, clean with a damp cloth or again with compressed air.
Deposits that have not been removed as prescribed can reach the combustion chamber and cause uncontrolled combustion there. Remaining deposits on the spark plug sealing surfaces may lead to leaks and the spark plugs may come loose during engine operation.
Spark plug threads must not be greased or oiled. Insufficiently tightened spark plugs may cause leaks and the sparks plugs may come loose during engine operation.

- Unscrew spark plugs using special tools 0 495 560 (12 1 220) and an extension piece with a joint.
- Always use flexible ratchet extensions. If rigid mounting tools are used, there is a risk of insulator breakages.
- Also, do not use a variable plug connection with a locking option as there is also a risk of insulator breakage.
