Thought I would resurrect this as it is precisely the same issue. It's probably the same damn car! :)
It has been getting worse, sometimes just a couple of judders then runs fine. Today it was in a right state wouldn't rev jumping around, wasn't good. Getting it back to the garage tomorrow, although I'd put money on it that il start it up and drive it there without a single hiccup!
So far dv has been replaced full service plugs etc coolant fans.
Really driving me mad, it's my other halfs car who is 5 months pregnant and is very worried to drive it now.
Thought coils but when it's running ok it's fine good mpg certainly moves along quickly too. If a coil was dead it would be running badly all the time. Also apparently no faults read...
If anyone has any ideas? Getting a bit stuck with this now. Only had it two months starting to wish I hadn't bought it...
Cheers
