Model:
BMW E38 750iL, 750iLP produced August 1998 – February 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:
The battery voltage needs to be at the correct specification, once this happens the engine speed will return to base idle. In order to do this using CD V22.0 or higher, reprogramme the ECM/DME of the effected vehicles, this will temporarily increase the engine idle speed but only if the battery voltage is below specification. The following services should be carried out on all effected vehicles:

• Replacement of Alternator on E38/M73TU
• Replacement of Battery Isolation Switch E38 M73TU
• Replacement of Vehicle Battery on E38 M73TU
• Retrofitting Adaptor Cable for MK II Plus
