E90 - 2009 335i:: jerk/jump when engine cold... Normal?

Greatdane84 · 01-31-2013, 05:53 PM

Hey guys,

So I've had my bmw now for about 2 weeks and have noticed on a normal basis I'm getting a jerk or jump feel affect every time I drive and engine/oil is cold. I quickly figured this out, that it was only until it started heating up.

Before anyone says go research, majority of what Im finding is related to a jerk while coming to a stop. http://www.bmw-sg.com/forums/bmw-3-series-owners/74249-gearbox-solenoid-change-jerking-problem-solved-e90.html
This isn't my situation..

While I'm stopped, engine cold, release break, hesitation and then a lurch forward. It's a little annoying and kind of embarrassing to have a nice car and go to give someone a ride and let them experience that. Anyone know what's the deal or able to point me to a thread discussing this?!?!? Thanks in advance

The torque converter lockup clutch can be disabled via coding.

Anyone know where this is within the coding? Tried the coding forums and couldn't find anything...

If you have a bt cable you can reset adaptations and see if that helps or get it scanned for any fault codes.

I was told Alpina B3 trans flash will eliminate this.. Will update this weekend

Just an update for anyone experiencing this issue...

The Alpina Trans flash DID fix this.

But it's annoying that it was there to begin with. I did find this link this weekend also, which does indicate that it's a known reported problem.

Not sure how accurate this site is. You do have to narrow down to the year...
