Team,

Thanks for all the feedback. Please accept my apologies for not being more forthcoming. I hope the following summary will be helpful in determining the issue I am facing and how I may be able to resolve it.

Make: BMW
Model: X5
Engine: 4.8i
Mileage: 65k
Production Date: 4.12.2009

I have a maintenance reminder on my X5. (For a picture of the maintenance reminder, please refer to the following link; http://www.xoutpost.com/bmw-sav-forums/x5-e70-forum/99228-anyone-know-what-maintenance-reminder.html) It isn’t one of the simpler ones you can easily reset. I initially tried to reset it myself through the stalk and idrive but it doesn’t offer me an option. A few months ago while at my local BMW Service Station in Port Chester NY to pick up a part I showed a snapshot of the Maintenance reminder to the Service Adviser from my phone. The Service Advisor recognized it immediately and mentioned the transfer case oil needed to be replaced. Once it is replaced, the maintenance reminder will need to be reset. He mentioned the service notification can go on at 60k, 100k or when needed.

A week later I took the X5 to my mechanic, a local indy specialist that works only on BMW’s. Without telling him what the Service Advisor informed me. He confirmed that it was the transfer case fluid that needed to be changed and the maintenance reminder would need to be reset. He changed the transfer case fluid (to spec) and attempted to reset the maintenance minder. However, after some time it just wouldn’t reset. He recommended taking it to the dealer to have it reset. I set up an appointment and took the X5 to Port Chester BMW. After two hours with it, they couldn’t reset it. They requested that I bring it back for a full diagnosis which may require removing some parts (didn’t get into detail).

On the way to my Mechanic, I stopped by Just BMW's, an indy specialist in New Rochelle that only works on Bimmers. He attempted to reset the maintenance reminder but after several attempts it wouldn’t reset. He told me, hold on I’m going to call a friend who works at a BMW service center. A few minutes later he comes back and tells me, in order for the maintenance minder to be reset, the software needs to be upgraded/updated.

When I took the X5 back to my mechanic, he confirmed what the mechanic at Just Bimmers mentioned that the reason the BMW Service Center could not reset the maintenance reminder is because the software needs to be updated/upgraded.

Unfortunately, after researching this issue, I have only come across one other board member who experienced the same issue. Unfortunately, I have been unable to reach him to find out whether he has resolved the issue.

Guys, my apologies for the long winded story, I was hoping to avoid it but I understand my initial question was too vague and required more detail.

I hope that someone can shed some light on how to fix this issue. Again, any feedback is greatly appreciated.

Thanks in advance.
