You back in the car yet? All resolved? (fingers crossed)
Yep. All done, got it on Saturday. Just washed it.

Bill to the warranty company was about £2600.

So just a very occasional stutter on idle? Idle is otherwise steady and smooth, just the odd little "blip" but no other symptoms?
Yep, pretty much!

Mine XF 5.0 was exhibiting similar weird rough idle symptoms, turned out to be dirty maf sensors, a 15 minute job to clean both and the issue was solved. If you haven't done this already, I suggest you try it.

Glad you got it back and even more so that the warranty picked up that bill!

Interesting, thanks for that. I cleaned the MAFs on my old 4.2 in an unsuccessful attempt to cure repeated fault codes relating to the MAFs so I might give that a shot.
