E87 Traction Control light

[momo1]

Hi Guys

I have an E87 M-Sport, I purchased a year ago.
iv never had any major issues with it and it drives really well.
except for this Traction control issue

every time I go over a very rough piece of road , the traction control light flashes for a about 2 seconds.
and I can feel that slight restriction
this only happens if im driving between 20 and 80 and the road surface is really uneven

I noticed it first when I just bought the car, but since it only happens once in a while and is perfect after those 2 seconds I chose to ignore it

i'm just wondering if I should be more concerned?
anyone else experience this?
what could the reason be? sensor perhaps?
or perhaps the big but standard 18inch wheels?

dont think there is much than can be done about that.. sounds like you are hitting the resonate frequency of the suspension under those specific conditions, meaning the wheels are spending too much time out of contact with the road surface, thus losing traction..

take it as proof that all systems are in fact functioning as designed :=):
