Peugeot 406 2ltr HDI 110 - Peugeot 406 clutch problem - mikescar

Hi guys.

Had a new clutch and dual mass flywheel fitted on Thursday at a cost of £565. I've done about 100 miles since and last night it started juddering.

As you go through all the gears and power up it vibrates through the whole car but when you take your foot off the pedal it stops.

Any ideas.?

Oh, i was told the make of the clutch is L-UK if that makes a difference
