Clutch Slur

BUT imho it does not always sort it permantly and often if for soem reason the compensator is not working correctly the clutch problem wil return. My first clutch was slipping on or off for 10k miles even though i tried to sort it with the reprogramming - but it always came back

Ive got to go through all this bollocks on friday at Murketts,they have to try this before they can give you a new clutch,athough Andy Pressland says it does actually stop the slur in a few cars,and he would know.says they have well over 50 CSLs on there books now.

Can anybody confirm or dispel this.

I don't think that's true mate as a guy on the cutters forum reckons he's done it about 30 times and his cars still on the same clutch and he reckons it's fine!

I think the 355 has a update/upgrade which
improves it slightly.

Thats without launch control etc.

Thats bollox mate, sorry. F1 clutches in Ferraris are pretty durable if set up correctly and used correctly. I'm yet to have a clutch in any of my F1 Ferraris (on my fourth) probably done 50000 miles between the four of them, fair bit of trackwork too

Doubt it'd eat clutches as there's virtually no slip when it engages (I've only ever done it once in my car and it scared the crap out of me and vowed to never use it again - I can imagine the stress it places on the rest of the car) - I'd say it'll rip the rear subframe out of the car before it burn up a clutch!!

Ok People there is a problem that bmw are not going to sort now

If you tell BMW to take the box out for clutch slipping and you are willing to pay for it as long as the clutch is worn below the limit thats fine.

BUT and its a big BUT if it is within spec i want warranty or good will to pay.

Thats how to tell bmw you want the clutch sorted as all the CSLs i have seen
and thats a few with some at 54,000 miles and the clutch was fine but flywheel had burn marks on it warranty picked up the tab

Hi

Hazy- F1 Clutch and sofware in a 355 is
about as crude as it gets, about twice as
slow as SMG 11.

Well known in the Ferrari world to gobble up clutches.

F1 Clutch in my first 360 F1 was gone in around
5500 miles from new.

Clutch in my second 360 F1, was gone in just
over 6,000 miles.

Third 360 was a Manual, clutch did 15,000 miles
plus and car was then sold.

Mates 360 F1 purchased with 5000 miles,
sold to HR Owen with 12,300 miles, at agreed
price, when arriving to deliver for payment
Diagnostic test shows clutch is 93 % worn.

Records show that it was its second clutch.

Its just like the 360 front wishbone bushes that always
seem to fail after about 4/5000 miles of hard use, and
you had to have complete arms both sides at
750.00 aside + Labour as Ferrari would not sell just the
bush/bearing, they have now changed their policy on
this.

2k for front wishbone bushes after 4/5k miles with a
clutch thrown in is not exactly what you expect.

On BMW M3 SMG 11 Launch control, there is
an article somewhere that confirms that with
10 launch starts then the clutch can be something
like 75/80 worn, it also mentions that 'slack'
or 'play' can result in the drivetrain as
a result of these lauanches etc.

The Gorilla.

Have never tried it on mine and i see it as rather gimmicky tbh. Why fit something to a car that will wear expensive clutches prematurely that only brings questionable/minimal benefit? Silly BMW

Me niether and the more I read about its effects the less i want to....

on the flip side i remember it did give the csl in that jap driver race video a really good start, you know the one with the m5, lambo, porsche etc.
