Also should note that it is a diesel.

Am in drive and engine turns over well apart from when it reaches around 2000 revs and cruising. If I increase acceleration or depress the clutch it stops the shuddering - for a while anyway but can reoccur at any minute. Only happens in forward gear as cannot imagine going at 2000 revs in reverse and reversing only tends to be brief. Once the shuddering had been overcome or has just gone away then pulling power seems to revert to normal. No high pitched squeals and no noticeable difference in the clutch pedal. Is a confusing and frustrating condition so any guidance would be most gratefully received.

Shuddering has got worse and tends to happen around 2000 revs, but again no idea why this should be as it does not happen when idling, only when driving and can be anytime, engine cold or hot. Due for service soon but any advice on possible causes would be gratefully received so I can advise the garage.

Had Terraclean done on my 2l diesel about a year ago but to be honest did not notice any real difference in performance. Just wondered if it was necessary in the first place.

Hi, I have the same problem with my 55 Reg Jaguar 2l diesel, around 91,000 miles. Think it might be something to do with the clutch as when it happens and I depress the clutch the shuddering stops and then I raise the clutch again it has gone away - until it happens next time. Am going to get my clutch checked out on next service in a month or so.
