hi everbody it's my first post on the site so here goes.

i recently bought a 54 reg 2.0 pd tdi (140 bhp) and at first all was well with the car then but then i started to notice that when in either 5th or 6th gear at lowish revs(70mph in 6th at 2200 rpm) when i tried to accelerate i felt a hesitation/juddering almost like a misfire.At first i put it down to me not being use to car but then the car cut out on two occasions having just come off the motorway and would not start, had car towed to garage where after alot of trying to find the problem (no fault codes at main skoda dealer) a new tandem fuel pump was fitted.This has solved the cutting out problem but the juddering at speed is still there. Has anyone got any ideas to the cause of the problem.

Crud in the fuel lines?

Sorry to say, but it could be a whole series of things....

I've had similar troubles..

Does the judder/misfire clear above 2.5/3k revs ? if so then it could be a bad connection on the injector loom..

I'm far from being an expert mind you.......

First thing to do is a new Fuel filter.

thanks for the quick responces guys, had the fuel filter changed and injector cleaner the first time the car cut out, car started but drove for about 10 miles then died again so new pump fitted,thought it might of solved both problems as i assumed they where connected.In responce to swil00 i can make this judder happen at 1800 revs in 6th by putting my foot down a little on accelerator and hold it there and it keeps on juddering until i reach 2500 to 3000 revs like you said, did you ever solve the problem on yours.been looking on the lines of the maf sensor or even the possibility its the dual mass flywheel (god forbid!) but will get the injector loom investigated. thanks again guys.p.s the cars only done 60,000.

If when you have it vibrating at 1800 rpm, you take it to about 2100 rpm, then lift off and apply the gas again, does it still happen? I think you're setting off the DMF with the additional detail you mention.

yeah, once you get the judder going at those revs you can maintain it by keeping it in the the rev range, but as soon as it gets pass it its fine. If it is the dmf is there any immediate panic to get it sorted as in is it doing any damaged to anthing else or will driving around it be ok for the time being.

I have exactly the same problem and I've been trying to solve it for over a year:

Fuel filters changed

Turbo replaced

Injector wiring loom replaced

Oil changed

Air filters changed

Still there and it is driving me round the bend!! Next up I'll be replacing the flywheel sensor. Have you noticed that it's worse when it's wet?

Well I'd start changing up a bigh higher in the rev range to try and avoid those revs and see how it goes.

If you're under a warranty get it done, if not keep an eye on it and don't be too hard on the thing as if it goes, it can make a mess.

There is a sticky thread in one of the sections here that i created that gives a DMF overview.

VOSA had a call on the Octavia mk2 2.0ltr engine 6speed manual gearbox here are the recall detail. CONCERN: Flywheel may fail resulting fire.

It has been identified that the two mass flywhell can become damaged because of a not optimally aligned through-flow restrictor in the clutch pressure pipe. This situation can lead to total failure of the flywheel and under unfavourable conditions a fire. Remedial Action: Recalled vehicles will have the make of the two mass flywheel indentified and if necessary, replaced together with the breather of the clutch pressure pipe.

On a 54 plate yours would have been one of the first 2.0 TDI's made and would definitely be in the scope of the DMF recall however your Skoda dealer should be able to rule this out or not, mine was under warranty when I first had the problem and after replacing the turbo under warranty I still brought it to a main skoda dealer who diagnosed it as a signal/wiring issue. Work is still ongoing but I'd start with the Skoda dealer.

My issue resolved, thought I'd post an update in case someone else has the same issues would have been nice to get an update from original poster. Looks like it was a combination of Injector wiring loom and bio-diesel being in my tank from previous owner. Replaced fuel filter when issue was found and it wasn't overly clogged then replaced wiring loom and all was well for a few weeks when it started again but this time needed to change fuel filter again and clean out tank. Drove without fuel filter to confirm and it's back to full revs.

hi guys, sorry for the late update on my engine judder problem, had the injector wiring loom replaced but still made no difference but have taken it to different indy garage for second opion and they have found that the 3rd injector is failing (its sticking open) so now waiting to have it replaced (650 quid, gulp!) will let you know if it solves the problem.thanks for the replys.

Getting to the injectors isn't a five minute job on the PD engine, they are buried inside the cylinder head.

A failing DMF usually rears its ugly head when pulling through 1700-2200 revs in 6th with the gas pedal on the floor. This is when the engine is producing it's peak torque which puts the DMF under the most strain. If the juddering is occurring during a light throttle input I would think its an injector/fuel related problem.

My DMF was replaced after heavy shuddering under the conditions mentioned above, it never did it under light or part throttle.

Is the indy sourcing the injector for you? if so, are they getting it from a dealer and how much are they charging for the part? there are a few on ebay for about £100 FYI :wonder:

cheers dstev2000, the juddering seemed to be at the 2000 rev range but think it was down to the fact that i was only seeing it when i was on the motorway after warming the car car up when i was going to and from work,but now it happens at any point when you put your foot down a little to hard ,the guys from the garage took it out whilst connected to VAG/COM and could see different reading from 3rd injector compared to the others(alot higher).the injectors costing £460 plus vat but is original part from dealer and only £100 to fit (mates rates do apply there to bo honest). fingers crossed it solves the problem cause had a poor start to my skoda ownership up to press (£1400 on parts and labour in first 6 month) but still keeping faith that all will be ok in the end.will keep you posted on out come. :|

oh so very common guys, i work for vag and we do loads of injectors, more commonly the passat though. mate of mine has a leon and his was doing the same, an injector wiring loom later and it was sorted, anyone running the 170 with dpf filters the sensors on these can also cause similar faults

Hi guys, finally got the injector changed on the car and it seem's to have solved the problem. The car feels totally different now, there's no sign of any judder and it go's like stink, if it carries on performing like this i'll be a happy driver again.Thanks to everybody for the advice on the problem and hope this helps anyone with a similar fault.
