my M3: oversensitive DSC?

[crosvs]

Hey everyone-

So after owning my m3 cabrio for about exactly a month now, i'm noticing a weeeeeeeeeird thing with my DSC (yes, i keep it switched on when driving on public roads). Basically, once it's invoked, it takes forever to give me my power back. Most extreme examples happened yesterday:

I came out of a parking lot and punched it to get ahead of an oncoming car. This was on Skyline Blvd up in SF, headed south en route to the 280-S. The lanes were about to merge, so I floored it in 1st gear and I guess the inside wheel slipped enough to cause DSC to start bitching at me. Expecting the DSC to just get over it once it realized I was going straight, I kept my foot on the gas needing full throttle as soon as the electronic nanny would allow it, only it was probably a few precious seconds before DSC finally decided to trust me and let the electronic reigns go.

Then, while doing the merge from Skyline Blvd to the 280-S, which is a VERY steep, downhill, 270* on-ramp, the DSC went bezerk as I tried to power out of the turn at the end: even after driving perfectly straight for at least 5 seconds, the DSC light kept flashing and would NOT give me all my engine power back until I let up on the throttle for a second or two, and even thehn, only gradually gave me more and more power back before finally shutting up.

Is this normal behavior?

Thank you,

Sounds normal to me, you were still on the throttle. Had you let it up, DSC would have gone stopped.

No surprise, it seems normal. The M3 has quite a bit of power, and BMW doesn't want the average driver to get over his/her own head. Since it also senses has gas pedal position, it determines when/if letting the reigns go would be appropriate. I assuming since you lost a bit of traction, it thought you were in a low traction situation.......at the same time you left your foot planted. Even if the tires hooked up momentarily, it probably decided that letting it immediately back to full throttle would have caused yet another loss of traction. Basically, you might know it's perfectly dry and okay.......but DSC might not and wants to keep you safe.

If your previous X5 was a xDrive equipped one, you probably aren't used to DSC coming on. On the xDrive models, I notice that DSC intervenes much later and much less than in rear-drive models.

You should be able to turn off the traction control for the DSC while leaving the vehicle stabilization turned on. If you just press the DSC button once quickly it will turn off traction control. If you press and hold the DSC button for about 3 seconds it will completely disable the system.

So it should still try and help you correct your rear end from coming around by applying brakes on individual wheels but not cut off your power. I know it was this way on a 6 series that I drove. I think it would be the same way one the M's. Also driving sideways is fun!
