My M3 has gone crazy!

I was leaving a friend's house tonight, and the instrument panel lighted up like 4th of July when I tried to start the car. Engine was running very rough, all kinds of error lights showed up..and my wipers just wouldn't stop wiping unless I power down the car. I turned off the engine and tried to restart..but then the motor just wouldn't start..

My idrive/AC/stereo basically the whole center console is not working/lit either, light in the trunk is also out....

Anyone else experienced this issue?

This happened to me and it ended up being the CAS unit and a few other things.

Everything was gone. You might be lucky and it might not be the CAS unit - but mine was and it took 3 week to sort out. (CAS must come from germany, and is coded to the key and car)

Good luck

This happened to my 335i when water leaked through my sunroof and made it's way to the computer system in the trunk. Apparently there was a recall on the sunroof, but they never informed me about it. After they fixed it, my (3 month old) car rattled like a 10 year old hyundai. Took months and countless visits to the dealership for them to find all the rattles in the car. There's still a few, but I got sick of taking the car in. If they replace your iDrive/computer system, make sure they put your car back together properly. Major service always scares the crap out of me.

It stands for "Car Access System". It's a type of module and if it needs replacement, it usually involves reprogramming the car.
