Model:
BMW E38 750iL 750iLP produced September 1998 – May 2000
Complaint:
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 a no-start situation.
Remedy:
A modified water-cooled generator with a new ribbed V-belt can be installed. This is able to cope with short journeys due to its higher generator voltage and higher current capacity at slower speeds. The following services should be carried out on all effected vehicles.
- Replacement of the Battery Isolation Switch on E38 M73TU vehicles.
- Replacement of the Vehicle Electrical System Battery on E38 M73TU vehicles.
- Increase of Idle Speed on E38 M73TU vehicles.
