Charging Operation With Battery Charger
In the case of charging with a battery charger in the engine compartment, the starter battery is charged via the B+ support point at the front of the engine. In the case of charging with a battery charger, the system battery is charged at the rear B+ support point on the left wheel arch in the engine compartment.
NOTE:
In the event of repairs or during diagnosis with terminal 15 activated, the battery charger must be connected to the rear B+ support point (engine compartment, wheel arch, left) in order to prevent the system battery from discharging.
