super s · 29th May 2019, 17:02

hello everyone.

can someone help me here...

have a ztt with super vibration at take over, i can even feel it in the pedal...
after that i feel it again, at about 3000 rpm at pressing hard the accelerator...

could be dmf?

from stand still, when you move off, does it sound / feel as if the engine has swung backwards and the exhaust has hit the body above or the brackets below?
This is a sign of the lower mount.
It is a simple and quick job to replace and test.
Remove it, hold the metal part in a vice, put a large screwdriver or rod through where the fixing bolts go and lever towards the front or rear. You may see the rubber has torn

Hi super s,

I must say, it does sound like the DMF. The problem I have with that is that the DMF almost never fails. Is there any clunking or banging or knocking noises accompanying the vibration? Maybe have a look at the crankshaft pulley/damper to see if the two halves (inner and outer) are separating. This IS a pretty common failure item.

Good luck,
Glenn

hi,
the vibration is really heavy, in the clutch i feel it hard while trying to move from stand still, and taking over ... also feel a bit of slipping or judder...

i am not sure about the clunking, i believe it also does.

apart from that the front bumper does not sit wright, it as a gap in the passanger side between the bumper and headlight and goes till end of the bonnet...

i believe it has crashed and is missing the some of the wing catches to secure that part of the bumper...

am i wright?
or should sit wright without the small wing catches???

Is the vibration there when the engine is idling and you aren't touching the clutch pedal?

If it isn't and you only feel it when you press the clutch pedal down then I think more likely the clutch release bearing is failing so it will need a new slave cylinder.
