Hi Everyone,

Hope someone can help. If I drive at between 30 and 40 gently, if you know what I mean, I get an awful judder. Driving harder no problem.

It is a TD4 with auto gearbox
The car has a Ron box fitted.

Vcu bearing rubber mounts knackered?

Narrowed it down, the engine seems to miss at times when under no pressure.

Injector fault. Does it go away if the Synergy is turned off?

Hi Nodge, not tried that yet, will try in the morning.
Thanks

Switched off the Synergy but the problem is still there. I think the missing is still there at speed, its just that its not so noticeable.

Almost certainly an injector on the way out. Using a synergy can cause injectors to fail as it pushes them harder.

Thanks Nodge, is there a way of telling which one may be the problem?

You could do a leak back test to see if one is passing more fuel than the rest. Alternatively get the set checked and or refurbished by a specialist.
