Hi all, my vogue l322 sometimes juddery when in idle in drive but ok under normal running/ acceleration, rev counter not fluctuating either seems to be using bit more fuel also, any ideas?

Cold be a sticky injector, run a Couple of tanks full of fuel with injector cleaner additive and see if improves, cheapest and easiest place to start. There is nothing that can't be fixed with a hammer😜😜

I had the same symptoms and have started this process ^^^^^^ and am already seeing some good results.

Especially with the cold weather, the diesel is a bit more viscous so you could be on to something here. I would certainly do this as the first attempt to solve the lumpiness. MY 2010 5.0 SC Galway green and sand interior!!
