WOT problem

wesley's m3 · 02-24-2015, 12:27 PM

Hi guys I was wondering if anybody could help me.
So I have a 2011 e92 m3 DCT and when I accelerate in 1st gear in manual mode traction on power off the gas pedal seems to vibrate like crazy. It vibrates only in first gear, its smooth after i shift. Vibration goes all the way to redline.
Not sure what's going on.

nice typo. But in reality, I'm not quite sure, sounds serious to me

haha fail on my part. I'm not sure what to do. The dealership says its normal, but i know it's not normal because my brother has the same car and it's not like that.

Turn traction control off and see if it still vibrates. I'm assuming it's a TCS issue.

Car 100% stock?

Weird does this only happen in 1st gear?

I don't think its TCS, he said it stops after he shits to next gear

Sounds like a transmission problem to me... It just started do it or you bought it that way or?r

I just figured he has more traction in second gear as opposed to first so there'd be less vibration. I'm lost on this one, though.

Is it this?

Used to happen to me in sport setting with aggressive throttle from start.

The car had a ideal actuator fault, but is still stalling. I have to bring it back to the dealer. It still vibrates when i turn the traction off. I don't think it's how aggressive the throttle is. I have a muffler delete right now, that is the only modification. I put 1000 miles on it and it just recently started to have gas pedal vibrations.

I my self am having an issue with my gas pedal in 1rst gear, my exhaust also sound louder in first gear then when I upshift it goes back to normal. Did you ever find out what the cause was?
