Caution! Switch off ignition; disconnect earth (ground) lead from battery and insulate it.
Disconnect plug from Hall sensor.
Remove Motronic control unit.
Remove connector strip.
Installation is the reverse of the removal procedure.
Switch on the ignition.
Without starting the engine, fully open the throttle once or twice so that the Motronic control unit can register the throttle-valve positions.
Note:
- Disconnecting the battery deletes all entries (e.g. faults, settings) stored in the Motronic control unit's memory.
- Loss of settings can temporarily impair the operating characteristics when the engine is restarted.
