Ignition stop
The control unit and the final stage inevitably fail if the engine is turned over by the starter with the high-voltage wire disconnected. Therefore:
1. 74 kW motor: Disconnect the connector on the final stage (next to the ignition coil) with the ignition off.
2. 92 kW engine: Remove the engine cover and disconnect the connector at the final power stage in the ignition coil pack.
3. 110 kW four-cylinder engine and six-cylinder engine: Disconnect both connectors on the final stage (under the lid) with the ignition off.
