Peugeot 307 1.6 HDI - Dual Mass Flywheels - Garnet

I have owned the above car from new since 2005 and it has covered just over 35,000 miles and been serviced by an Independent Peugeot Garage. Within the last couple of weeks I find that on switching the engine off a continuing whirring noise emanates from the engine and lasts for 6 secs approx. The garage informs me that the fly wheel is at fault and that I can expect a repair of £800.What is your opinion

A DMF does not 'free wheel' when you turn the engine off. The noise is either the A/C or cooling fan or may be, but I doubt it, the turbo. Does the whirring noise wind down or does it just stop. Regards Peter

Clearly not!
But the noise might be poorly described-a broken DMF spring would rattle upon switch off. I'm puzzled too, but I doubt the garage plucked the diagnosis out of thin air.

I did consider that but springs do not whirr and last 6 seconds this is why I asked if it winds down ot just stops. As you say it is strange that the garage diagnosed this as a DMF problem. Perhaps the garage were looking for the whirring but noticed the dreaded DMF rattle when turning off so there may be two faults and a communication problem. Regards Peter
