  Note
t  When installing new spark plugs, the ignition coils must be regreased with lubricating paste -G 052 141 A2-. In doing so, the sealing hose of the ignition coil does not “stick” to the spark plug. The lubricating paste must spread over the spark plug when fitting on the ignition coil.
t  The new ignition coils with power output stages are supplied greased.
