I have a 2008 x type 2.2D. There is a judder which is worst

Customer Question

I have a 2008 x type 2.2D. There is a judder which is worst in 6th gear when doing 65/70 mph at about 1750-2000 revs. Any idea what this might be? It does not judder under braking. Have replaced all the discs and had the wheels balanced and the tracking done. At a loss what to do next.

Hello

this could be worn mountings - check the tightness of the engine and gearbox mounts and their condition - this is best done by using a jack to take the weight of the engine off the mounts and seeing if any cracks or splits open up in the rubber.Also check the tightness of the mounts bolts

it could also be a slight misfire so check the connections to the EGR valve, if either the vacuum pipe of electrical connection are damaged / corroded then the EGR can be on all time which certainly will hurt performance. Its also possible that its a fault with the EGR valve so its worth removing the valve and cleaning it out with brake cleaner, if it looks particularly clogged then replace it.

it would also be worth replacing the fuel filter as its only has to be slightly clogged to give issues
