TECHNICAL INFORMATION
Clean spark plug slot with compressed air.
The spark plug shaft must be cleaned using compressed air after having removed the ignition coils and before removing the spark plugs. After having removed the spark plugs, once again check the sealing surface for contamination and (if necessary) clean using a moist cloth or clean using compressed air.
Deposits that are not removed according to instructions may enter the combustion chamber and lead to uncontrolled combustion. 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.

NOTE:
The description is for one component only. The procedure is identical for all further components.
- Unscrew the spark plugs with the special tool 0 495 560 (12 1 220)
and an extension with joint.
Flexible ratchet extensions must always be used. If rigid mounting tools are used, there is a risk of insulator breakages.
Also, do not use a variable plug connection with locking capability as this poses a risk of insulator breakages.
- Unscrew the spark plugs with the special tool 0 495 560 (12 1 220) and an extension with joint (1).
