Mk7 110 T300 MWB Engine Judder FWD

Postby LowSlungDub » Sat Oct 10, 2020 6:31 pm

Hello! New to Transits!

I've searched the forum but not found any fix for the issue I'm having;

At around 1600-2000RPM in 4th/5th I get a quote violent Judder, like the engine is rocking. It only does it when I'm feathering the throttle and starts off gentle and slowly gets worse until I have to let off the pedal and then reapply power which solves it for a few mins.

I'd love to get to the bottom of this, it's only done 120k and been very well looked after!

I have read many things on driveshafts, egr, dirty inlet, etc but would like to know what to check first!

Hope I've posted this in the right place!

I'd be looking at the fuel rail pressure on live data while recreating the affected parameters

Is there any fluctuations (hunting) while at idle?

No hunting at idle, it feels like a backlash somewhere.

It only ever does it when lightly accelerating to keep around 50mph in 5th and 40mph in 4th. As soon as I accelerate or take my foot off it's fine again.

The engine pulls well, no smoke at all which is strange for a Transit

Check the drive shafts/CV joints, they can give grief sometimes under certain conditions.

Knobrot, you're the reason I joined, you came up in a few searches saying driveshafts and it feels as if there's slack somewhere like a driveshaft, I wouldn't think the DMF is faulty as it drives really well and pulls of better than most things I've driven. How would I go about checking the driveshafts without taking them out? I'm used to VW stuff which is all I've ever owned in 15 years of driving.

It's fine at any other revs in any other gear. It's not got worse or better with an EGR clean, new fuel filters, inlet clean etc. It definitely feels more mechanical. I guess I'll check the shafts and then the DMF just to be sure.

Process of elimination really, if it were EGR, dirty inlet or fuel filter related, it would do it all the time, yours clearly isn't. CV joints get a wear pattern which may only cause issues at certain loads and speeds. It's difficult to diagnose unless you disassemble them though.

Is the vibration at wheel speed..?? If so it can't be any of the engine related items like the DMF etc.

I'm not saying it is definitely a CV joint causing your problem but it is the most likely. RWD transits never suffer from the same symptoms as they don't have CV joints. I'd suggest it's the inner drivers side CV joint which is the culprit, if it were outer joints, they would knock on full steering lock.

Just my humble opinion.

Another problem! Not sure if it's related but coming up to traffic lights this morning it cut out, like the revs dropped too low and it just turned off, started fine and drove fine to the next set of lights and same thing and then couldn't get it to do it at all so ran fine for another 4-5 sets of lights. Hope this could be related!

Mine does similar.

Deffo feels like a running issue rather than drive train. It’ll sort of miss as it goes along on a steady throttle getting worse and worse if you let it. As you say, I let off for a few seconds then apply more throttle and vary the revs and it seems to sort itself.

Also experienced the stalling. Only happens when the engine is hot, like coming off a motorway to some lights etc. Sometimes needs to be left 30 seconds before it’ll restart.

Learned to live with it. This van is a trooper. 225,000 miles and had very few parts. Original clutch etc.

Another problem! Went to leave and it wouldn't rev! Then did, then didn't, then did but sounded like a low droning noise, then drive fine, it hangs up in the revs, sounds like it's hunting at idle but the revs aren't changing, fiddled with the throttle pedal and it drove home ok but not 100%. I've only left VW once and already starting to regret it. My trusty Passat has 330k on the clock and it drives like it did when it had 60k on the clock.

Disconnected the EGR, no change, took it off and cleaned it, no change, cleaned MAF, inlet pressure sensor, crank sensor, checked for air leaks in pipework, done some googling and I can only see that there's something called the SCV and PRV, the SCV is like ticking/crackling and then when it stalls it's buzzing like mad.

I've read you need someone with some magic box to teach the vehicle when fitting new ones, does anyone know who can do it near Gloucestershire? I don't mind fitting but I don't have this box people talk of unfortunately. I have VAGCOM though!!

That's the thing, if I were to change them, how badly would I need to teach the pump or not at all? I need this thing running tomorrow.

I have exactly the same problem on my 08 110 Limited FWD with 142k on it. Replaced everything chaps have suggested on here with others that have had similar issues. both drive shafts as well..I have come to the conclusion it’s play in the gearbox. I just live with it now. I do have a slight whine in 5th gear. It’s a 5speed..Even changed the gearbox oil just in case...Did make it “slightly” quieter....

I Have another 08 110 FWB with a 5speed as well that van has 58k on the clock and doesn’t have this issue at all.

I didn’t have any history with my 142k transit so didn’t know if it has a Dual Mass FW but assume with that mileage it’s been changed as the van has a tow bar it would of done some work!!....

The quest to solve this issue continues haha
