M3 DCT Clutch slip?

[benm3evo]

Hi,

I've got an E92 2010 car with 40,000 miles on it.

In the last month or so I've noticed what I think is slight clutch slip. When I pull off from cold I change gear manually (as it does like to hold the revs in auto) & when in second gear & accelerating gently the revs rise but the speed doesn't.....then after a few seconds it seems to sort itself out & drives as normal. It only seems to happen when starting from cold.

I went out in it last night & it did the above, but then on 2 separate occasions I noticed a judder from the clutch when pulling off in first.

I have to admit I analyse every slight noise etc from the car so I'm wondering if I'm being over fussy? I don't know a lot about the DCT but do understand it's a wet clutch system so doesn't wear like a normal clutch?....so at 40,000 miles it should be ok?

I have 6 months left on a AUC warranty so I'm thinking I'll just call them & I guess they'll book it in. Just wondering what other people's opinions/experiences might be?

Thanks muchly.

Never used the launch control in the 6 months I've had the car, that's not to say it wasn't used in the past I suppose. I think I'll just call & get it booked in then....& request the X5M courtesy car too haha!
Thanks for the reply.

Booked in for tomorrow! Will report back on what the outcome is.

A good shout re. asking if they can tell what wear is on the clutch & the times it's been launched....or perhaps I don't want to know that bit!

Cheers, Ben

Cheers for the advice guys, all taken onboard for when I take it in tomorrow. I will report back. I have to say that all dealings with the dealer have been really good so far....haven't been talking about anything so potentially expensive yet though!
Cheers, Ben

Update for anyone who's interested (a bit boring I'm afraid)....

They've had the car this morning & done an 8 mile test drive, they can't find any faults. It doesn't really surprise me as it didn't do either symptom this morning on the way there.

I asked if they can tell about clutch wear & they said they can't without removing the clutch, which sounds fair enough but I don't know.

Anyway, they've said to take it back if it does it again. I probably won't bother unless it gets much worse as it will probably be another waste of time. I suppose at least the fault has been 'logged'.

Cheers for the advice.

Thanks for the re-assurance!

It sounds like mine is doing exactly the same. I am always a bit of a pessimist so fear the worst!

I do plan on taking out the warranty when this one runs out. From what I've read they do seem pretty reliable but you can never be too sure.

Thanks for that, just had a search on M3 Cutters & have found a few threads re. the software update. Will give the dealer a call back in a few days & tell them the issues are still the same (which I'm sure they will be) & suggest the software update & see what they say.

Cheers, Ben

I think it is probably a combination of my lack of experience of DCT & also me worrying too much! I will still ask about the software update as that sounds worth while.

Stories like that definitely re-emphasize the importance of a warranty. Would not like to even guess the cost of a new engine or gearbox.

Cheers, Ben
