It is possible to estimate clutch wear with the AM diagnostics system apparently

Interesting - I specifically asked HWM at last year's service to estimate clutch wear. Was told it can't be done without dropping the gearbox.

Yeah I'm confused by that as I've heard the opposite a few times
That said
Ferrari & Maserati have used avery similar box and can give a % clutch wear from their diagnostic systems
I wonder if it only applies to sport shift as the ECU will have calibration info for bite & kiss points that could be used to estimate wear

2012 V12V Carbon Black - 2900 miles, no signs of any problems (and i really hope i dont see any for a while).

I have to reverse into my parking space so hopefully that doesn't affect things too much.

That's a good point
Is the V12V manual the same reverse ratio as the V8V manual?

2008 4.3 Manual - 28k clutch died - on the Mulsanne straight!! Replaced under Warranty

I'm not sure... we need someone's technical expertise on here!

Out of interest, isn't the V12V clutch a twin plate affair?

(So very different to the single plate, 'made from chocolate' V8V version).

I have the twin plate from BR on my 57 plate V8. The original agricultural V8 clutch started slipping at 21K miles. Once removed it was obvious that the plate hard warped and only the outside edge of the clutch was in contact. Hence the slipping.
The twin plate is a transformation. It is light, no juddering and with the lightened flywheel allows for a quicker pick up.
If your clutch is ready to go, I would recommend it. Don't bother just upgrading the clutch, have the lightened flywheel while the car is in bits.

Was your BR clutch for a manual or a SS?
I live quite a distance from BR and was thinking of just buying the parts and using a local specialist to install. Not sure if they will sell me the parts alone.
39k miles and no clutch slip yet. But I am expecting to have to replace it in the near future.
If you don't mind telling, how much did they take for the updated unit?

Thanks

What we need is for someone to ask BR when they are next there - is it possible, is it only on ASM etc.

IIRC, BR won't sell you just the parts.

They can, however, collect your car in a covered transporter.

The price is similar to a standard clutch exchange, but I think you had best contact BR for prices.

OK then, can they come collect it from my house in Florida?

Will do ,
Thanks for the info.

Yes if you ship it in a container!

Anyone had any more clutch incidents?
Please vote and post if you have.

[lime1]

Manual 4.7 V8V 2010. 9300 miles from new with no problems.

[notsaV8V]

Is everybody contributing their experience also voting? Makes quite interesting comparison so far.

Of those voting:

Failure rates

ASM1 20.8%
ASM2 50.0%
V8 Man 33.3%
V12 Man 11.5%

Sample sizes are small I know but it seems the ASM1 doesn't compare badly at all despite the anecdotal horror stories.

This data has absolutely no meaning. A clutch is a consumable, and your above summary makes no reference to the use seen before failure.

[mikey k]

Yep it is interesting to see ASM1 is not the horror story many assume
