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 *****ing 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,

--Marc

 

hows your tread in the rear...also with sport on you have to be especially smooth on the controls during maneuvers, and take generous lines through the crappy roads around the peninsula. Find a smooth onramp to 280 in a straight line, off of skyline or milbrae ave and get a feel for how much dsc will hold you back when running through the full band on each gear, or just sign up for more track days for dsc off fun.

 

i never use the "sport" mode -- i find the throttle annoyingly twitch during normal driving, though i suppose it would be quite nice at the track. yeah i don't have any problems in a straight line, really, it's just if there's any obvious slip of the wheel. in other words, it seems to work fine, it just keeps working far longer than necessary -- not always, but often enough that i felt i should inquire about it.

 

Part of the reasons why I got rid of my M3...as much as I loved the car.

 

My M3 had the software update that removed the speed limiter and made the vehicle always in DSC-off mode when the car started up. This car is the most fun with it off and as long as you are a good driver there is no need to fear. Hell just 10 years ago most avg cars didn't even have it.
