(my11 tdv8 4.4).

On one of our annual French trips. The ffrr is the wife's daily so I take the opportunity to drive on these good long runs.
I noticed same issue last year but as the car is not my daily and I do often get to drive it for long periods at motorway speeds, I forgOt about it.

SO thacking long for hours at a time At...ahem...motorway speeds I occasionally get a slight stutter on lumpiness on the accelerator. No warning lights And the symptom isn't cOnstant. Thoughts?

Get exactly the same. There's a thread in 'Technical' somewhere on the 4.4TDV8 doing this. Dealer denies all knowledge because no fault is logged.
