Hi,
Just had my 2005 C2s serviced and dealer said clutch felt heavy, just a note on the invoice.
I am thinking of having the 2 year warrenty next April when my present one runs out. The car drives well and the clutch dosnt slip although I agree it is heavy. Does this mean the clutch is on its way out, is there an easy way to see if the clutch is ok without taking everything to bits?
Cheers.

Heavy is often a sign of a worn clutch, but warranty won't help you as it's not covered.

My C2S (2005) wasn't overly heavy; certainly no moreso than a non 'M' BMW if that gives any point of reference.

The GT3 clutch is a weighty beast by comparison; not entirely dissimilar to my first car, a Golf Mk 2 GL smile but somewhat better in every imaginable way.

Do they actually have a helper spring on these boxes?

Its done 29,000 miles, 1/2 of which are motorway miles so not too stressfull on the clutch. Is there any way to check if its on its way out without it being a huge job?

Does anyone know the answer to this?

I bought my 997 C2 with a heavy clutch (compared to 2 other 997's I had driven) - negotiated a discount on the basis that the clutch was probably on its last legs.

Got it straight in for a new clutch and sure enough it was on its last legs and also somewhat "warped" according to the garage. New clutch was much lighter.

It should be, but the amount is a bit mis-leading. They are very light when new, then the springs in the pressure plate temper somewhat with use so it settles to a slightly stiffer pedal which is normal. This means if someone convinces you your clutch is heavy when it isn't, a new one will indeed feel lighter, thereby justifying their diagnosis. You really need to compare to a car with a worn-in clutch to see if yours is worn out...

To be honest, if the clutch weight is not bothering you I'd leave it for now. Dealers often try it on with changing a clutch. 40-50K miles is about the average life of these clutches and yours sounds like it doesn't get particularly heavy use.

I'd park it on a severe gradient... A certain OPC told me my clutch was okay, and it did work fine on the flat, no shudder or vibration etc. Parked it on a hill with the OPC technician in the passenger seat and it 'shuddered/vibrated' a little on release. OPC changed it forthwith. (4K from new! - main thrust bearing or something like that...?)

I presume they changed it under warranty on the basis that it wasn't actually the clutch that had worn out then? Is the main thrust bearing part of the consumable clutch kit or a separate part? If the bearing was separate, did they change only the shot bearing to fix the fault or put a new cluctch pack in too?

Just trying to understand the logic of the warranty.

Hi mate, they changed the whole clutch assembly (as far as I could ascertain at the time) and yes presumably on the OPC warranty, and given the low miles etc, it was pretty much a no-brainer. I couldnt tell you about the thrust bearing thing, am presuming it was all part of the same overall assembly, But anyways it did behave differently on the flat than on a steep gradient.. it wasn't heavy or anything like that, just the shuddering on the hill start....

I also (within 2k of this issue) had to take the car in for a slight 'pause' or misfire under hard acceleration...nothing showed up on the OPC diagnostic computer.. but I stood my ground, they replaced one coil pack, then another, then another...problem still there...

Again, OPC technician in the car and thankfully the problem repeated itself and Technician confirmed the issue..... End result Dirty/knackered MAF sensor! ... but I did thank them for the new coil packs too......
