that's comical

it's stuff like this that kills cars residuals, FFS it's a flywheel, not a complete engine!

(know of quite a few cars getting dumped by owners because the bill to fit new DM flywheels is approaching what the cars are worth now).

Surely there is enough meat to skim the flywheel at least once?

The issue isn't with the thickness/flatness of it, it's whether the 2 parts of the dual mass flywheel are still working together correctly or not....

I'm sure there will be aftermarket normal flywheels available, but you'll get more NVH as a result

What sort of miles have you done? I assume it's started slipping?

Dare I ask, ballpark, how much? rolleyes
It's done 52k.

it's not slipping, it has horrible judder when hot. Also there is an issue with depressing the clutch pedal far enough to start the car. I think there is an issue with the pressure plate tbh.

The flywheel is now available from the likes of Euro car parts for £442, the total cost quoted for the change is £1390

I thought (but could well be wrong) that I had read this was something separate, some switch that controlled this, rather than the clutch itself? Maybe it was on RS246. Can't remember now.

Is that parts only? (if you're doing it yourself). Seems a lot for just parts (if the main dealer will supply AND fit for £929), and the DMF (parts only) from ECP is £442.

The issue is the switch is in the master cylinder, the slave cylinder can't reach full extension due the the issue with the clutch so I need to push the clutch pedal down with full force to get it to start.

The quote is clutch kit with updated clutch arm etc and flywheel fitted, I looked at doing it on my driveway but can't be bothered in this weather!

I've waited until my 8.5 has done some decent mileage to loosen up (circa 3.5k atm) but I am absolutely convinced my old car was quicker. New one just doesn't have the vigour (all relative I know) of the old car. Must get it on a rolling road at some point to compare.

Might be down to Euro 6 rather than Euro 5 emissions approval? Or the change in supercharger design....

I wonder if they have tightened up the bph output relative to the older car - i.e the new one is actually producing the 330 or so it's supposed to instead of the 360 that most seep to produce.

this^^^^

throttle response is somewhat 'duller', the cut in NOx limit's means the last thing the engine wants is sudden changes of the throttle.

economy wise, ignoring stop-start, nothing really in it that I have noticed.

My daily commute over a mix of country lane, dual carriageway and 3 miles of in town stuff, old car was always mid 22mpg...new car hits 26mpg.

Saw 30+mpg once in 4 years with the old car, new car only needs to look at a motorway for 10 minutes and breezes 32mpg

interesting...

our first one overall average (40K miles) was 29.1

current one is at 15K, and it's showing 29.3

Our 2011 Sportback is much the same in terms of fuel use - low to mid 20s. Never got near 30mpg even on a motorway run

Mine only has to cruise on a dual carriageway for 15 mins and it'll be showing 30+mpg.

25-26mpg on the motorway... Sits at 3krpm though, newer cars are longer geared I believe?

I guess so. Noticed yesterday at circa 60/65mph it was only just over 2k rpm

Not really - steady state cruise set will see high 20s. I don't go by the instantaneous figure and only tank average reset at each fill up. Add a few cold starts and it plummets. Need to do a proper tank average check but last time I did it was only noticeably cheaper on fuel than my 4.2 s8 because of the price difference between regular and super!

It doesn't particularly bother me, clearly, given what I drive. It'd be nice to regularly see 300 miles between fills
