SUBJECT
Oil Service Interval Incorrectly Coded in IKE

MODEL
E53 X5 4.4i/4.8is produced from 01/23/05 up to 02/22/05

SITUATION

Service Interval Indicator in the instrument cluster displays a need for an oil change after approximately 500 miles of driving (no green lights remains in the Kombi display).

CAUSE

Incorrect coding data for the instrument cluster (IKE/Kombi).

CORRECTION

On the affected vehicles, prior to customer delivery, or the next time vehicle is for service, or on a customer complaint basis, recode Instrument Cluster/IKE with DIS CD40, CD 40.1, CD41.1 (when available), or higher.

[NEW]DO NOT PERFORM UNNECESSARY OIL CHANGE ON VEHICLES WITH A PREMATURE OIL SERVICE INDICATION.

IMPORTANT:
Do not code IKE/Kombi with DIS CD 41.0 when it becomes available (planned release in the mid March). CD41.0 contains the same Kombi error and it is not going to correct the problem.
