Clutch slips - possible reasons?

[Porker]

My car is at the workshop, initially to have the clutch changed, but apparently my clutch was still in good condition.

They then 'reteached' the SMG clutch biting point, without result, clutch still slips for about one second after every shift. They'll now bring the car to an official BMW workshop to check if the SMG has all software updates necessary, I have no clue whether that could be the culprit, advice would be most welcome. :beer:

Before I bought mine from NJ last Feb, it had a clutch slip problem which BMW Oxford diagnosed as a worn clutch. NJ duly replaced that (even although there was clearly little wear on the clutch itself) but it still had the problem so he put it back to BMW Oxford who on further diagnosis replaced the actuator. This fixed it.

This can be the sleeve the release bearing runs along
Mine did this and after the new sleeve it super fast changes

Then i believe i have driven your car sir! Infact my first time may have actually been with your girl :119: :smt055. It was at the begining of those problems when I went to look at at, so I steered away and tested a few others. Glad to hear its been fine for you.

Do you still deal with Oxford? I've been less than impressed by them.

Very helpful guys, thx!

Could be. It was 41k miles (04 plate) & at that time NJ had a 15k miles one in - I had a hard job telling which one had the lower mileage such was the excellent condition of the one I bought. To be fair to NJ, he made sure the issue was properly sorted before I got the car. I'm in Edinburgh so have had no further dealings with BMW Oxford.

I doubt that it would be the actual clutch, they're usually good for 100K smiles
More likely to be the actuator as previously stated, comparatively cheap fix :supz:

I guess it depends on the comparison (against something much worse?), but BMW Oxford charged NJ £1250+VAT.

Yep, thats the one! The 15k looked way worse for ware, cosmetically at least, than the 41k car (i saw them parked side by side).

Ordered a new clutch actuation pump, hope that'll solve the issue. Will let you know!

Mine did this quite a lot, Initially BMW just put new clutches in as they couldn't fix it, the old ones looked fine but a new one fixed it for a while each time.

Eventually they put a new SMG ECU in and it was fine for ages.

+1 Sleeve or actuator......

+1 Sleeve or actuator......

+2 on the sleeve .... stupid dry fit design - once you get a small wear mark on it it bloody catches and then wears more and eventually you get sticky clutch release - mine had this and was replaced under warranty - otherwise the clutch and pressure plate were as good as new.

Shit that would have been expensive...I am sure the accumulator is available separately from the pump??

I have no idea to be honest, the garage said it was considerably cheaper than a clutch, so I assume they've only ordered the accumulator. Will check and let you know when I collect the car.

Still not sure if that's indeed the fix, they should work on it tomorrow.
