How to detect DMF failure

[olearysp]

Could anyone advise as to the symptoms of dmf problems? My 150 vectra c has 124k miles and has started with vibrations when in drive ! It is on its original clutch and DMF, though the clutch biting point is at teh the top of its travel.

The garage will often advise for a DMF change upon changing the clutch, or say they found the DMF to be dead when they'll disassemble the clutch. Don't know it's so often with the vectra, but it's a fact.

Now diagnosing a dead DMF by yourself, no worries, you'll just hear it pretty well ! Loud and clear !

Got mine done at 70k ..£890 but now am at 93n noticed the other day as if it runs on after I run the engine off . When I dip the clutch it doesn't do it .. any ideas ?
