Does anybody else find the M3 very jerky in 1st gear?

[quackbury]

Not to bust the OP's b*lls, but his sig says he has a 2007 M3. AFAIK the last model year for the E46 was 2006, while the E90/92/93 debuted in 2008. What gives?

First E9x M3s were delivered in 2007 in the UK.

LOL, really. Even though I explained it pretty thoroughly?

Ok my bad, it was a different thread. Same OP tho.

So using that logic, the 2011 X5 I am picking up next week and the 2011 F10 I test drove at the UDE in August are both "really" 2010 models?

Does that mean I can legitimately call the leftover 2008 E93 that I bought in February, 2009 a 2009 model?

Been over this before but in the UK, they tend to ignore the model year designation given by the car maker and label based on when the car was sold/registered. So even though it may be a 2008 to BMW, the buyer purchased and registered the car in say Sept 2007, it is a 2007 in the UK...

I thought I was the only one who had this issue....

[shiggy]

sit in your drive way for 60 sec and then drive off....my DCT is that way but i let it idle for a minute and its completely fine!

What kscarrol said. Our conventions are not the same as those in Europe.

when shift from 1st to 2nd, you just have to hold down the clutch pedal a bit longer, let the RPMs drop a bit more then you release the clutch....

Of course, this technique does not apply when you are racing someone or on the track when minimal delay between shifts is required...

Funny,

I have only had the 2008 M3 for 4 weeks now. I read this post yesterday and before that I never experienced the bucking. Really did not pay too much attention to the post.

Today is the coldest day so far in Alberta that I have driven the M3. The first thing I noticed is the throttle was not that responsive coming out of the Parkade. I would ease on the throttle and the car would not move. I drove for a bit, car warmed up, and had to make a quick left turn. Stomp on the throttle to make it and the car hesitated for a count. Scared me as I needed to move quickly through. I had to stop somewhere for a few hours parked it. Afterwards I drove out and let the car warm up close to the 100 C mark. Stop at the red light. I decided to test the hesitation to see if it would happen again. Stomped on the throttle and the car started bucking like crazy!!

I was in automatic mode and I have DCT. Is this common experience? Is there a new throttle software map to fix this?

Thanks

Will

yah but so does ever car, and it's only because the throttle response it so crisp. bring up the rpms slowly then mash it in 2nd and go go go

[JCtx]

Engine is going to be jerky until fully warmed up. We don't have a MAF sensor, so it's perfectly normal. But once fully warmed up, nothing has better throttle response . A drawback of having 8 butterflies vs one with a MAF sensor. Oh yes, and guzzling gas like crazy is another one .

You are right - for those having an issue we should try changing the fuel pump ( to replace the filter ) as it may be the case that the old one is starting to clog - the issue is more noticeable in cold start as the engine is mapped to a rich mixture which exacerbates the problem

You are possibly experiencing a minor loss in power when fully warmed up as well - one way to check I'd if the car decelerates gently in 2nd gear when you let the accelerator pedal off fully on a level road or if it slows down quickly

I have the same issue and apparently it's common - the fuel filters are labeled lifetime ( funny design )

Yep, slow release of the clutch.

Are people driving in sport mode (power) or no?

[Helmsman]

Ha! Back from 2010, relevant topics never die.

[fatalelement]

My DCT is the same way, even warmed up. It's uncommon, but sometimes when I downshift into higher revs even with a tender foot application it kinda see-saws back and forth with the revs naturally because your reaction to the jerkiness is to back off a bit and it just wobbles the car. It does make you look like a bit of a jackass in 1st.

I try to stay out of 1st if:

1. I am moving faster than about 5 mph
2. I plan to not have my foot down

I tend to only be in 1st if:

1. I am starting from a stop
1. I plan to keep my foot down or almost all the way down until 8,000+

(DCT) Mine did this when I first bought the car. Every time I start the car, for the first minute or two it would be very jerky at low speeds. I learned very quickly that to combat this, I would put the transmission in manual mode (on S2 setting since cold engine), and would shift at 2.5k rpm or hold the gear when coming to a stop. This eliminated the issue completely.

It seems as though the DCT's brain needs a few minutes to warm up prior to calculating everything correctly. Perhaps it just needs its morning coffee?

[nrubenstein]

There’s two parts to this:

1) The cars don’t drive that well while cold.

2) You’ve got a a super responsive engine with ITBs hooked up to an electronic (numb) pedal. This requires a little finesse because there’s just no feel at all in the pedal. The same as the S54. The S50B32 is a totally different (and wonderful) driving experience because you still have the cable throttle and ITBs.

Maybe its not the car.. Warm your feet up

i upgraded to the GTS DCT tune couple of weeks ago haven't seen the same jerking since.

I'm not sure why everybody is always complaining about a car that has a personality... if you want an ultra-smooth car go buy a boring Audi

[RC Post]

Can bad motor or trans mount cause the jurkiness?
