Are dual mass flywheels ever fitted to petrol cars?

In Honest John's column in today's Telegraph, the reply to 2 letters about clutch judder is that it is probably the DM flywheels at fault. However the letters do not say anything about them being diesel. Hence my question.

I'm not too sure about HJ's reply.

If it's the dual mass flywheel, why does it only affect the first clutch use of the day?

Yes, that occurred to me too. Maybe they warm up after the first use and become more pliable. But if it was failing I'd expect symptoms most of the time.

Number cruncher is misquoting me. Take a look at the FAQ at www.honestjohn.co.uk/faq/faq.htm?id=115

No, I'm not, I'm referring to your response in yesterday's DT motoring supplement, which, given that both questions state that the problem occurs with the first application of the clutch does not point to DMF in any way, yet, that's what your respose talks about.

Unlikely to be the DMF most likely oil on the clutch plate, but this is a man who still talks of chain cams so limited mechanical knowledge!

And yup some petrols have been fitted with DMFs like Porsche 964, 968 & lots of mercs as mentioned

"the first clutch use of the day"

That's more likely to be moisture (condensation), IMHO, esp. if kept outside.

Could also be that as well.

Yes, I think that's a much more plausible explanation than the DMF.

Mercedes has been fitting dual mass flywheels to petrol engined cars since the days of the W201 (190). Starting with the larger engined variants, it was introduced in the W124 across the range. As far as I know, all subsequent rear wheel drive Mercs have been fitted with DMFs (though someone with better knowledge may beg to differ). In practice, as almost all Mercs have automatics, this means not very many.
