PLEASE HELP
I am experiencing extreme engine judder.
I recently bought a 2009 207 sw s 1.6 hdi 90.
It is the single mass flywheel version.
It's only covered 39000 miles.
When depressing the clutch on take off in first gear, also in reverse the engine is juddering to the point that you can hear it violently moving back and forwards.
You can also here and feel this, all be it no where near as bad when gearing down from 4 th to 3rd ECT.
I've fitted a new 3 piece LUK clutch kit and had the bottom 2 gear box mount bushings replaced.
I've taken it to a gear box specialist who has said it's not the box.
Nobody can tell me for sure what it is.
I've had all the engin mounts checked and also been told it's not the bottom pulley.
Also been told by another garage that it's either the flywheel or gearbox or both.
Don't want to chuck loads of money at it fixing things and still have the same problem.
Strut top mounts and wishbone are also fine.
Only happens when depressing the clutch.
The engine runs clean and smooth when not depressing the clutch.

Had a very similar issue, had a 307 2.0hdi with a single body flywheel conversion.

Took the car in for a clutch change, sourced a valeo clutch kit, had it fitted, and the car juddered as the clutch bit in first and reverse.

Took it back to the garage, they couldn't find the reason why it juddered. They said it's likely to be the driveshaft, perhaps the splines were worn and were jumping/camming out.

It got slightly better over time, but never went away.

My personal thoughts were that the flywheel was warped or loose. Maybe it was misaligned. Unfortunately I never got to the bottom of it.

Thanks for the reply.
I am thinking it's the flywheel.
It had judder before I got the clutch done but became far worse after the new clutch was fitted.
Probably due to biting more.

The garage did say that the clutch might need to bed in to the flywheel. But that wasn't practical as up-hill starts and moving off were dangerous as I needed to give the engine over 2000 revs just to get it moving.

Problem solved.
Flywheel had an imbalance.
Totally fucked the new clutch I'd
Put in 500 miles ago though.
New clutch and skim the existing flywheel for anybody with the same problem.
