DSC Brake ABS lights plus....

[tomsawyer]

Hi Everyone - I have a 2005 4.4i (N62 engine) w/ 75k. Here's what happened:

- 6 weeks ago, I'm driving along about 35 mph on a flat road and all of a sudden the truck momentarily hesitates for a split second and simultaneously the 4x4, BRAKE & ABS lights come on and at the same time the radio shuts off, screen goes dark and then the radio turns on by itself. I return home, shut off truck, restart a couple of hours later and everything is normal (no lights or warnings) and it stays that way until last week.

- last week, I'm driving the same way, about 35 to 45 mph, truck hesitates momentarily (I'm talking like for literally a split second) and again the 4x4, BRAKE and ABS lights turn on and radio shuts off and turns back on about 5 seconds later. I turn off car, restart and lights still there. Truck seems to drive normally. Next day, start truck - all lights gone.

- a couple of days ago, again I'm driving and this time only the 4x4 light comes on and this time the radio happened to be off but the navi screen turned black and then came back on. Also, this time, in the orange letters underneath the odometer, a warning comes up says "DSC/4X4 Inactive".

I had a guy who's a former BMW tech run a diagnostic (supposedly he has the bmw software, and he pulled the following codes.

*002A1D
*0029DD
*0051AD
*004F7A
*0000BD
*005F3A
*005DDO
*005F02
*005E52
*005E28
*005E44
*53FC

I realize there's a lot of codes and there's the usual posts about the 4X4, Brake & ABS lights coming up but I haven't found a post about the radio shutting down and restarting but itself.

Anyone have a clue as to what may be going on?

Thanks to all who answer.
