BMW Key Storage

I bought a new M3 from my dealer that had been taken on some test drives and was wondering how I would be able to tell if the car had been taken to the redline at all during the break-in period. (P.S. I kind of got ripped off paying 3k over and now realize that )

Sorry, don't know how you could tell about redline before you got the car, but what does this have to do with key storage

I don't think that info is stored on the key memory, but a memory dump of the CPU would have some stored data. On the E46 they could tell max. revs and amount of time over certain revs. I would guess the E92 would have more capability.

I believe only service information and check control functions are stored on the key, and the key has to be in the ignition. For many with comfort access that rarely happens. I found this out taking my car for service my Service advisor read the key and nothing was on it. After a quick insertion into the ignition it was spewing out fault codes! I am sure BMW's computer would store how the car was driven just for a maintenance point of view. However getting this information from a dealer is another story. Unless you blew your engine like I have read some has already done.

Okay, I wasn't sure if info was sent to the key wirelessly. The manual is not very clear.

The dealer can tell you if it has been redlined

I know this for fact that they can tell since they are trying to use it against me in my quest for a lemon law settlement. BMW Customer Care mentioned that it clearly states in the report that the tech pulled up an over rev code. I did not do it and always break my vehicles in according to specs and inquired a my local dealer. They told me the car was indeed over reved at one point but exactly when is not possible to decipher. I was not the first to drive car and suspect a salesman or prospective buyer did it upon test drive. I hope that that info helps..

In your case, unless the can time and date stamp the "events", there is no way to prove whether you did it, or some lot jockey or tech while it was in for service. A good lawyer would have that "evidence" dismissed in no time.

Would you be able to point me in the direction of sites/places I can read about this? This is the first I've heard of motor problem(s) with the S85 and I want to stay as informed about this as possible as I do plan on tracking my car.
