Got a real head scratcher for you here.

Bought 2008 T5 2.5TDI 130 Shuttle automatic in August last year. Had van at my house for a total of 74 minutes before AA took it away with bad intermittent vibration 9long story short, (Sales garage have got away with selling me a lemon!).

I have to say that i was completely convinced it was a drive shaft as it was initiated on acceleration but was still there, once it started, until speed was declined. Both have been changed, even wheels tyres have been changed. Still there!

Van was then taken to John Mackies in Glasgow for gearbox testing, faults found on pressure testing so instructed them to rebuild box and replace gear oil cooler. Still there. they describe it as shuddering on engine load between 30-50 MPH.

Engine starts fine, no smoke. No loss in power (on the 4 mile test drive I did before AA took it away.

Any ideas at all guys, I am now £12.5k deep into this now and really need to get this sorted before the AA need to come and take ME away for a rebuild!! Cheers

I had a strange vibration (also a 2.5, but a manual) that took some chasing down, including tyre/wheel changes - in the end it was the tandam pump (IIRC, other members have has this same issue).

I had similar symptoms with my 2.5 AXD, juddering under load at 30-50, seemed to go as you got to bigger speeds. Ended up being a blown head gasket/burnt out valve seat crossing over between cylinders 1 and 2. May I suggest a quick compression test as this will be ruled out if all is ok.

Welcome to the club! Just bought an 06 Shuttle 2.5 130 and its turned out to be a turkey as well. In conjunction with the many other things it does, vibration under load at about 2000rpm is one of its traits. I thought driveshaft, as it judders like my old DAF when the prop centre bearing went. Just had the fault codes read on it though and its coming up as intermittent misfire on injector 3. Don't know why yet. If you are not 100% certain its mechanical / driveline vibes get someone to do a diagnostic on it.

Ok, thanks guys, although I can't seem to work out how an engine issue could cause such a vibration/ judder. But yes it is looking like top end attention is needed. Just wish the van was not 200 plus miles away from me right now (Scotland is lovely but big too!).


Thanks for the welcome btw.

Hi mate, tandem pump, i am new to T5's! I am guessing this would be the second fuel pump or high pressure pump which supplies the injectors? If so how much did it cost to replace please? Also did it throw up any codes on diagnostics?
I do hope it is this though as it does sound cheaper than a top end rebuild.

Sorry to jump in and answer someone elses question, but yes that's what the tandem pump is. There are two pumps, one lifts the fuel out the tank, the other tandem pump boosts the pressure up to feed the injectors. Its called a tandem pump because it also creates vacuum in a secondary chamber. Its driven off the end of the camshaft / mounted on the side of the head. Euro car parts do a new one, for under £400 if I remember. There is one on eBay just now in Coatbridge for £60, but before I rushed in I would get a proper VCDS code reading done. There are other ways to check this too, fuel rail pressure check / drop off test etc, well documented on here. I've got all this to do to mine, the one common thing from the other members threads is that having a guess and throwing parts at it can be a bottomless pit. You need as many clues before you start as possible, and getting the diagnostics done shouldn't be too expensive. That said auto boxes are an odd thing, so rather than pre-empt anything best to see what happens when the box is rebuilt, the garage may be right enough.

Jump in all you want mate. This is the problem I have got as the gearbox has been rebuilt including oil cooler (£3680). There was a previous rebuild done 1 year ago but oil cooler never changed. When Mackies tested box two weeks ago it was pressure building and there was coolant in the oil so oil cooler had failed and damage was imminent in box anyway.
So yes, diagnostics is the next step. I will keep you posted on any outcomes as this stuff is helpful for members on here (lol stating the obvious there I suppose).
I guess I need to find a garage in Scotland who has experience with the 2,5 derv engine. Reading peoples posts on here I am guessing not everyone knows this power plant to well.

briand has covered most of it but the fault on mine did not throw up any codes.

Well you won't believe what the cause was in the end. It was the fuel filter!! Causing fuel starvation under load! I have no doubt that I had issues with the gear box but I could never have guessed that it would be as simple as the fuel filter in the end.
Learning curve is reap in the T5 ownership lol.
Take my hats of to John Mackie auto gearboxes in Glasgow though. They have systematically checked everything to find this. Far beyond a gearbox specialists in my mind.
Thanks for the advice though chaps, I can now see why it could well have been a tandem pump!! A:

Well, that was as lucky and as cheap as it could be! That must be a weight off after all the potential expensive things it could have been. Lets hope I will be as lucky, I already have a fuel filter lying about and will change it tomorrow.
Enjoy your van!

Can't wait to start enjoying it! Yes it was a cheaper fix than it could have been. Certainly a learning curve though. Although at £90 for a filter I can almost understand how people can skip changing that! Cheers for the help though mate.
