As a result of frequent short journeys with a large number of electrical consumers switched on, an adequate charge level may not be maintained by the vehicle’s electrical system battery which can as a consequence result in the vehicle not starting.
To find if a vehicle is affected by this Service Action then the Service Menu of the Dealer Communication Programme must be employed. If necessary after the results of the system continue with the corrective action or take no action at all.
If the vehicle has been affected then install a larger capacity (70 Ah) system battery and a new battery holder. The following services must also be carried out:
- Replacement of Isolation Switch on E38 M73TU Vehicles.
- Replacement of Water-cooled Generator on E38 M73TU Vehicles.
- Increase of Idle Speed on E38 M73TU Vehicles.
