Hi everyone. Well my 2002 M5 is now 6 days old and today I had quite an experience. As I was driving for say 30 seconds I noticed that my tachometer was not working. About 1 minute later I pulled into the supermarket parking lot, and turned off my car. I then noticed that my tachometer lights (the one orange and red) were still on, even though my key was out of the ignition. Also my on board computer lights to the side were still on but I could not scroll through to any of the functions. My central locking system button worked inside the car, but the remote lock & unlock features did not (only the trunk release).
I put the key back in and tried starting the car, it would turn on for 1/2 a second (like it had turned over) but then went dead. Keep in mind the tachometer lights are still on, as are my reverse lights for no aparent reason.
I finally called BMW Roadside Assistance (or that poor excuse that they call road side assistance) and they sent a tow truck. The towing guy was very helpful. Before trying to tow me he tried jumping the car. That didn't work. Then he disconnected the battery for a minute, then reconnected it and now my car starts and works fine.
One thing is that my time, date, consumption, trip counter, etc. are all reset (everything in the on-board computer). I figure this is just from disconnecting the battery.
Anyway, do I have a lemon. I mean WTF. The car is only 6 days old!!!

As BMW is closed, I will drop off my car first thing tomorrow morning but now I am afraid to use my car until. What bullshit is this? Anyone have a similar experience or any comments/ideas?
Thanks guys!
