Juddering Puma
My Puma engine vehicle keeps having a regularly recurring issue – not a big problem but a bit annoying. It does not do it all the time and does it at all temperatures and I think in all gears.

To describe the issue, the best I can say is it kangarooing - It judders as if it is about to run out of petrol and will judder 10 or 20 times or more (at perhaps half second intervals) - The only way to stop it when it's doing it is to keep it in lower gears and rev it more.

Any ideas?

A known issue, I believe there is an existing thread or two about it on here somewhere. Steve.

Search function is fifth link along from 'Home' in the blue strip under the title header. Use 'rev hang' as your search subject. It is a common issue and one I believe there is still no fix for.

There are even a couple of Kangaroos in the search to keep yours company...... Laughing

firstly lets hope it's nothing to do with petrol. Mr. Green

as ever it's probably going to through you off on a wild goose chase but might be worth checking all the same - I only found this recently and have owned the def since new and bar 2 services have done all the filter changes myself........

is the fuel filter on properly?

below shows 3 marks. 1st being where you engage the filter and the 3rd being fully fitted. 2nd mark being where mine was fitted.

no cost potential fix so worth a try. good luck.

I did try a search under judder juddering jumping kangaroo and got no results

K9F - thanks for the link
Caterham - thanks I will mention that to the dealer, but it did this before the recent first service so I doubt it will be that

I may be barking up the wrong tree , but filled it up today and added some Redex diesel additive to see if that makes any difference

My 2.4 occasionally does these little surges, especially when cold. Driving at very low revs while feathering the throttle when cold does it and I either change down or just give it a bit more right foot and it will go.

Morning Gents,

I thought this was due to it being fly by wire and the "mismatch" between the two at low revs and speed.
It was a little annoying at first but happens less and less as you get used to it.
I didn't think this was considered a fault as such and I've just adapted my driving to work around it.
I'm interested to know if anyone has had this looked at by a dealer and have had it fixed.

Mark
