Any ideaa? My Dynamic Stability Control (DSC) light occasionally comes on during my 35 mile drive to work. Happens about 1 or 2 times every 3 or 4 days. It will come on about 10 minutes or so into the drive but while be off later in the day (after its parked). I've tried turing it back on by the DSC switch but it seem uneffected. I was told if it was malufunction it would stay on. Any idea on the cause?

There are so many sensors in our cars...tough call to make from your post. Is your car still under warranty? However, until you can reproduce the problem, I doubt that the dealer will be able to find anything but it is possible the computer might have stored some codes that could clue them in.

I'm sure this isn't the case, but, I need to ask as it has happened to others.

Did you NOT use the cupholders during the times the dash DSC light lit?
Oftentimes, unbeknownst to the driver, the object in the driver-side cupholder presses the DSC switch, turning DSC off (at least that portion of the DSC that can be turned off) and thereby lighting the DSC light in the center of the dash.

In a way, it's a cupholder-in-use light. :)

Nothing you stated indicates this is the situation; but, I'm just double-checking the basics for you and for the next person with this same issue.

Good luck with your DSC. The good news is that only a portion of the ASC/DSC is actually turned off when you press that DSC button (according to my Bentleys).

I only wish it was as simple as something in the cup holder... but this isnt the case. I had thought it might be a dirty wheel sensor. I notice today that it blinked on for about 3 minutes ( as a steady speed) and went back off again.

Anyone else ever had this problem? My DSC light comes on after driving my car for about 45 minutes. It always resets and goes off after I turn the car off. When I start the car, evrything is normal. It used to happen after 20 minutes of driving but I removed the front wheels and tweaked all the cables and now it happens after 45 minutes. I suspect it is a front wheel sensor or cable that may have been bumped while replacing my control arms but the symptoms are a bit strange. There were no codes when it happened the first time (then I lost my Peake). Any thoughts on this? Thanx.

BTW, my cupholders are locked into place and are never used.

wheel sensor.
+1

I have replaced 2 since I purchased my car. Go to a shop a and they will tell you that its the control module or pump and they will try to charge you big bucks to fix it. VDO makes a good sensor for less than $100. Takes about a half an hour to fix once you know which sensor it is.

Keep us posted.

WOW....I'm kinda getting a similar problem. On my 02 745Li, Upon startup, I get a "DSC Malfunction" message immediately followed by another message of "Engine Failure / Reduced Engine Power" displayed on the I-drive & Cluster screens. The car wouldn't allow me to accelerate. It would rev High to Low, over and over. So I waited, started it again and NO changes. Still having the problem. I tried to drive the car out of my driveway. Pulled out of the driveway, and I was jerked back and forth from the High/Low rev. I pulled back into the driveway, let the car sit for a while with no change.
Anyone have this problem or know how to correct ? The car ran all day today with no problems...blink and eye and all this stuff mentioned above starts happening.

Would disconnecting the battery help ?

Any help would be greatly appreciated

Are you talking about the wear sensors on the brake pad or an ABS sensor ?
Would this sensor trip the DSC ?
