weird thing has occured about 3 times over the last couple weeks. if i'm sitting at a light, and i start to accelerate normally, the engine bogs down and the traction control light flashes, for maybe a second or two. then the engine goes to full power again. i guess the car thinks it's losing traction.
every time this occured, the pavement was dry and clean.
what would cause this?
by the way, car is a 06 550i auto.

lol how many lead wieghts in your right foot? , seriuosly though have your rear tires got good tread, are they worn?, i have found mine needs good tyres with plenty of tread or
the traction control complains alot

Theres a speed hump around my way that sets of the stability control when i go over it slow.

tires are new. i wonder if maybe i'm just hitting the throttle too quick.

yup

It happened to me on stock wheels as well, but recently after installing the sprint booster, and running 22" rims, I never seen the traction control kick in so many times. Of course its the heavy foot

throttle too quick and the type of road. the mall parking lot near my place is horrible/fun. if i turn dtc off, i barely have to try to spin the tires

This used to happen to me when I first bought my car. I found it very frustrating not being able to use the power the car had (why get a BMW V8 if it doesn't launch any faster than a 530). Swapping the run flats for normal Michelin Pilots and installing the Quaife LSD solved the problem. Punch the car now and it launches extremely well. The acceleration is awesome, better than my M3 in day to day driving due to the V8 torque and great traction I now have.

Yes, this is a terrible problem with BMW V8's especially when you turn off DTC. Sometimes there will be an annoying odor of rubber burning and a loud squeeling sound. It's very frightening.

I don't have that. The one place where my traction/skid control light goes off like a Christmas tree is in the twisties when I am push the car to its absolutely max in M2 or M3 (I have a 2009 550i Sport with Steptronic).

I rarely see the light go off when I am just accelerating. And yes, I have a lead foot when it comes to acceleration (although not so much when it comes to cruising speed on heavily patrolled stretches of highway) and back roads.

i also get the same kind of symptoms when my car tries to move its ass asap.

Disable the system by pressing and holding the DSC button for around 3 seconds, this disables the system fully. Do the same test you mention above again and see what happens, if you see smoke coming from the tyres and the RPM's go nuts your mashing the gas too hard, if not and the same almost stalling feeling happens again maybe you have another problem
