I can't reset the oil inspection meter I brought it out to dealer but they can't find the problem? It displays a negative number but the number doesn't increase?? Is there a way to work around it or I would have to replace a new one. my bimmer is a 325i.
It helps to know what year a car is when addressing problems. For oil service, and all other routine maintenance, it's simplest to maintain based on mileage rather than the car's service indicators.The Bentley shop manual for your car has an excellent maintenance schedule you can reference.
I spoke to reps at Bavarian Autosport (bavauto.com-800.535.2002 - yeah, shameless plug) and at Crown BMW in Greensboro, NC. They both provided the same information: the indicator counts down to 0 miles and then continues into the negatives if not reset, and bottoms out @ about -15500. If you can't reset the light via the dash sequence and the dealer can't reset it with the GT-1 computer then you probably have a problem in the wiring harness, either in back of the instrument cluster or under the hood. The problem could be a corroded connection or a fried wire somewhere. Problems like this can be time-consuming (if you do it yourself) or hideously expensive (if you pay someone else) to rectify. Replacing the instument cluster would run about $500 for the cluster and $100 for having it coded to your car, and if the problem is in the wiring harness it would solve nothing. Hope this helps.
