clutch slip

AA121 · 20-11-2009, 02:05 PM

Hi,

New to the register and wondered if anyone can offer some advice on the following;

I have had my car around six months now but recently when changing up the gearbox it feels as though the clutch is slipping. Not sure if it just my imagination but it seems as though it is getting worse especially under any hard-ish acceleration.

Presume this means I need a new clutch!!! but thought I would ask if there is any other possible causes before taking it into a garage.

Whilst on the subject of garages...I live near ML but are they still the place to take an M car to for things like clutches?????

Cheers,

Tim

my clutch was changed after 45k miles, same symptoms.

My gut feel is if you get the clutch retaught early on it will put off the slip but no evidence yet to that effect.

Some guys just drive it hard on S6 and it goes away, but all in all if you leave it slipping too long it will ruin the clutch it seems

I've got the same symptoms, very jerky setting off, clutch slurring on changes even with traction control off and in S6. Driving me mad.

I’ve read it could be the SMG software not compensating for clutch wear and hence searching for the biting point, going to give BMW a call tomorrow to book it in. They may be able to re-calibrate the biting point ???

Thank god for warranty. (I hope)

Stick it in S6 and use hard acceleration. Don't lift on the change, bang it through and see if it is better after that.

Lifting on the change will make it seem like it is slipping, however it may need the most drastic action mentioned above...

Thanks for that..........how long do you think it will need to be driven like that before it drives better?
Perhaps I am driving it a little too sympathetically it's just that it seems to change a lot smoother if I lift when selecting another gear!?

A few months ago mine went in for an oil service. Went in slurring like they do, came out sharp as nails with not a hint of slur. I asked them if they'd done a software upgrade or perhaps a re-teach and they said "no... all we do is clear the error logs". Within a few weeks it was back to it's usual self. I may pop in and get them to do 'whatever they did' again just to see if it actually does make a difference - that would be a revelation!
