Oh its probably more dangerous to take photos whilst driving on ice than it is to drive with dsc off on ice

No goons at Bedford on the 30th. Everyone was well behaved, except one CHAV in a TT Supra who fancied himself against the CSL but lost it BIG time and went off track, ploughing

. Soon after, he was Black Flagged and invited to leave

Did an experiment this week.

On Tuesday mine was slurring like someone after 30 pints on the S5 full throttle (no lift) shortshifts at around 4,000 RPM. It had been like this for a while.... so....

For the last few days I've driven just the same (still S5 etc) EXCEPT I've lifted slightly on the shifts, so that I don't get any slurrrrrrrrr.

I go out today and decide to try the old full throttle no lift changes again and guess what - no slurrrr whatsoever. Insta-changes & sharp as a knife! Won't slurrrr even in the slightest.

It's 'learned' to be perfect again.

Ok, my slur is also back so i will try the same thing next week. I am off south and west for 3 days with work and play and will drive a day with slur flat on changes, then a day with lift and last day flat changes again and report back!

I have a slow M3 not a CSL but I have developed this problem too so I thought I'd chip in.

Car has 30k, 54 plate, nothing wrong. Drove 3000 miles inc 'ring and it was whacking me really hard, perfect engagement of clutch. Went up Stelvio, tons of passes, flat out on the a'bahn; my clutch was good

I got BMW DIS on my laptop and one night back in Novemeber I hit the 'Reset Clutch Curves' option. It asked me to start the car, so I fired it up, felt it pulsing the clutch to find the bite point and it was done.

Well I wish I hadn't done that now because from then till now it slur's! I've reset it twice since, done a full gearbox teach in, basically all the options.

There is no point to the story really except that it just goes to confirm there is some issue in the software that just doesn't learn the correct way to release the clutch.

Hard driving for a few hundred miles helps but its is always bad on a cold morning and never fails to slip at 4-6k full throttle.

I know my clutch was fine and just hitting a button caused this issue, fecking mad with myself

(I have the BMW work instructions too, so I'm almost certain I did everything correctly but I might try taking it to someone...)

Ive just had all the updates done to stop the hesitation in gear change and found anti slip kicks in as soon as I boot it even when changing to 2nd and 3rd

I haven't done enough miles or driven it like it should be to see if it sorts its self out
