Need help, knocking noise at biting point

[qianjizhao]

I got a signum 1.9 120bhp.
In the recent few days, there is a strange noise when at biting point.
Sounds like a kind knocking, and more like a kind of resonance.
I can clear hear that noise, only at biting point.
No noise when change gear, car runs fine, no lower loss.

Sounds like it is your DMF going.

As William said, sounds like the DMF is on its way out. Then again some people have had the knocking sound for thousands of miles and still the car has kept going. Appears to be a bit hit and miss when it eventually will fail.

Mine's knocking too

How much to replace DMF?

[qianjizhao]

BTW does anyone know a good garage near Chippenham ,which can double check this problem?
Thanks

£800-£1200 unfortunately. Happened to my last car (Mondeo TDCi) - hence why I changed.

checked with local VX, ask for £1461.61.
and a dependent one ask for £1200.
Seems like I need go to A1 clutch in Birmingham.
Someone said they only charge £640, 2 yrs/18K guarentee.

Booked in with Local VX to make sure that is the DMF problem on tomorrow.
Vx charge me £30 to check it, and they said will be no check fee if I let them fix it.

Got call back from A1 , they only ask for £540 for flywheel and clutch, and that price include parts and labour.
