I am getting all kinds of errors popping up on my dashboard and iDrive, so I bought a new battery last week, but as you can see with this video shot yesterday the same thing is happening again. What could this be? Please HELP!

I'm assuming all the things that are coming up as errors, are or seem to be functioning correctly? If so, then obviously a "monitoring computer" is malfunctioning. I wouldn't blame it on any specific sensor because you seem to have several different errors coming up...I saw a "Check Engine Light" and a "Steering" error. I think you have some kind of computer problem....and that a trip to the dealer to diagnose/fix this problem is in order.

Unfortunately, this is the exact kind of problem that makes the modern/new cars a pain in the ass compared to the older simpler cars. But it's the price we pay for "progress" and all the new/cool things these cars can do.

PLease let us know what you find out.

Thanks for the comments, everything works great as I keep driving on. Once I shut the car down and restart the car, all errors go away to back another day. Could it be the battery and reprogramming the new battery? I guess i'll have to go pay the dealer a visit.

either alternator or MPM

Id start with resetting the Idive - pressing all eject button + mute button and holding them until it resets.

Then check your boot/wheel well under the polystyrene. If there is any water in there it can ruin things i drive related.

I brain of the I drive which is in the boot like I said.

Why not give a better explanation mate, the Micro Power Module is located in the boot under the foam padding in the wheel well, its not the brain of anything but it controls power flow around the car.

This only applies to cars before sept 2005, the MPM is very fragile and water will cause it to go BANG!, check if it is damaged, cars after sept 2005 had the MPM removed and intergrated into the safety and gate way module.

As other members have suggested it could also be the alternator.

Thanks all, i'll check the MPM that is located in the trunk and then the alternator.
Does anyone know how to get the alternator tested. Can I take it to AutoZone and have them test it while it is on the car?
