mk7 juddering/jolting/kangarooing under light acceleration

[kevincego]

My 2008 2.2 140 euro iv have the same synthoms but the outside temperature is about 18°c. Someone talks about engine mounts, it os possible a bad engine mount do this?

I’ve fitted the 2 new sections of the passenger side intercooler pipes and as of yet haven’t had the judder/hesitation but I haven’t drove that far really to tell yet.

I have same issue, not that bad but someone told me that it could be faulty engine mount...

Yeah I've read that too, I'll have a look at the mounts. Fingers crossed it's that straight forward! Somehow I doubt it

I'm afraid I can't answer that,only ever worked with Fords own diagnostic equipment,
If you have the ability to update the pcm,I'd do that also.
Make sure the fuel filter,and fuel quality are good also before doing these resets.

Great thanks, I'll try using this ELM/FORscan thing to look for fault codes and if not I'll find someone to do what you suggested. It's due a service anyway so I guess I could get Ford to have a look.

Where are you based? Don't suppose it's anywhere near Gateshead?!

Cheers

Has anyone been keeping check on feul level during the judder?

Mine doesn’t seem to do it when I fill the tank but only starts when it gets below half. Possible breather problem maybe?

Didn’t mean to just quote it with no attached comment, sorry.

Are the intercooler pipes a cheap replacement part?

The nearside pipe is about £100 and the offside was £35. The juddering has returned slightly but not as bad as it was before the new pipe. Ive got forscan this week and found p0671 glow plug open circuit cyl 1 so this is my next check. Its also developed a rattle that i cant find. Hope its not the chain.

Has anyone had their 'monitoring gear' plugged in whilst the van is juddering? I would but I don't have any.
Just wondering as I have noticed that the tacho needle which is usually a smooth sweep and sits stable at chosen rpm, moves about if the van is juddering. Where do they get the tacho feed from, ecu or alternator?

I believe the Tacho sensor is on the flywheel.

ah that'd explain the needles unsteadiness then

my vans definitely loads worse now it cold....

My judder is completely cured now, i had a P0671 code (not viewable on cheap scantools), i got 4 glowplugs changed. Cylinder 1 glowplug had failed with an open circuit. All sorted now and im getting 39.7mpg average.

Well, this made an interesting if confusing read.

Mine just started doing the same, just a few of weeks after a mechanic solved the black smoke problems! A couple of weeks later he also did some things to try to solve an oil leak, I'm not sure what he did, but he dismantled something at the top of the engine, then re-siliconed it and put it back together. I have no idea if it is connected to the kangarooing, but it started 2 days later.

The engine idles at 800 rpm, and it has lost it's usual diesel-type torque, I find myself nursing the clutch like it has become a delicate petrol engine. Yes, it happens when I take my foot off the clutch, or when I put my foot down (on the accelerator!) And there is no real persistent problem. It doesn't stall, or even try to at all other moments.

Looking at the last reply, I should probably take it into the mechanic for a diagnosis??

[Dazza007]

How many miles has yours done? I've been getting poor performance and a smell of an old diesel in the back of the van, I checked the dipstick and found the same smell in the dipstick hole going into the engine, it was the brass rings at the base of the injectors were letting gases past. Smell your dipstick hole.

I think the problem is that the different posts are possibly describing a different judder, and are not all the same.
Yours sound more like clutch judder

A clutch judder Altransit? I would never have imagined that, but what do I know? I can't even imagine how that fits in. Would that happen even while I'm accelerating, no foot on the clutch? I mean, it kangaroos all over the place, as though the fuel is being cut off, but it doesn't stall...

That's what led me to think it is clutch judder

Ok, I'm guessing here I don't actually know the mechanics of clutch judder. Is it possible to say which part of the clutch is at fault Altransit? I mean, the van literally throws itself around all over the place.
