I have the same issue with mine, only now & again from stand still
sorry to resurrect an old thread...but I have the same issue with my car! It's under warranty (approved used warranty) and with BMW as we speak, their diagnostics machine say its running fine - but I know its not! The tech took the car for a road test with me in the car (nearly loss it in the wet but that's another story) and he said it felt normal...he also went on to say he drives a 120d as a daily, so of course it would feel good in comparison.
I am rambling on to ask...did you identify the problem in the end?
Have you tried it in MDM mode to rule out traction control?
could be the start of the throttle actuator fault
I'm too much of a p*ssy to turn traction off in the wet... I've only had the M for a few weeks and don't want to bin it into a hedge just yet.
When I boot it I never get any traction lights flashing on the dash?
You could be right...one went a few weeks ago and its only a matter of time before the other goes.
BMW would only replace the one as it was a warranty claim. It's only a matter of time before the other goes.
If you want a fast getaway and the TC is on it can be very intrusive and feel like the car loses power\jerks, I purposely engage MDM if I am going for a smaller gap in traffic. MDM isn't full TC off but doesn't interfere as much. You can hope it's that as it's cheaper than throttles.
If you are kangarroing it could also be down to the fuel, I had this when using shell vpower as others had the same issue on here so I did as advised and changed to BP ultimate = problem solved
Booked the car in with bmw and had it reprogrammed and that sorted out the problem
shell Vpower ISN'T good enough??? thats the first i've heard of that.
What exactly did they do, i'd be interested to know?
Indeed, I thought VPower was the fuel of choice, certainly it's what I always try and use
Just my anecdotal 2c, i've used v-power nitro for the last year with no issues so it seems to vary from car to car.
I do find Shell nitro varies in quality from garage to garage and even from the same garage.
Whether its because its a low demand fuel and so sits in the tanks for longer or whether sometimes they fill the underground tanks with standard U/L (by accident or on purpose).
In any case every now and then I get a duff fill and the car feels off...once it was so bad the car started pinking after a minute or so. I contacted Shell to complain that the fuel was the wrong Ron but they refused to go to the garage and take a sample to check. Trading standards were as much use as a chocolate teapot as well.
A rough cold idle (next cold start after a fuel fill) is usually a good sign of a fuel quality problem.
I filled up last time from a different Shell garage and my car is absolutely flying at the moment so I'm fairly confident that Shells fuel varies in quality.
My car hates v power, runs perfect on momentum. Have tried various Shell garages and the result is always the same - lumpy and jerky below 3k. Back to momentum and all is good again.
Well IL be damned, I too though shell v power was the one to have
Might aswell stick Tesco juice in to it now
Mine loves V-Power.
