I had my 54 Octavia 2.0tdi 140bhp serviced @60,000 and decide to do the cambelt just to be safe. I also had the gear linkage done as gear changes were not as smooth as they used to be.

I thought of it as a birthday for the car, sad as I am.

Since then the car kicks out a smallish cloud of black smoke on start-up (not seen before) :S and feels 'lumpy' and as if it is pulling when on the idle.

Garage has said Dual mass flywheel is the issue. It was as smooth as a diesel gets before the 'service', now I'm looking at a hefty bill. Don't want to change the car, would only go Octavia again, but I wonder whether it is coincidence that it was runnig ok before and after a service it has issues.

Any help most welcome.

Could be that the cambelt hasn't been done correctly and something is mis-aligned or something? I can't see the DMF being an issue at 60k.

Who changed the cambelt, dealer, VW specialist or local garage?

The new cambelt will be shorter than the old one but with same number of teeth of course. That means that the cam with the new belt will be slightly advanced relative to the crank compared to what would have happened with the old one. I think that effect for a preventative maintenance change would be very very small though, much more likely they did something wrong when changing it, much too much of a coincidence in my opinion.

Been a couple of posts like this recently, and the outcome has generally been that whoever did the belt did not correctly lock the fuel pump properly.

The PD140 requires that both cams and fuel pump be locked during the belt change, failure to lock all three can result in a loss of timing and strange running issues because fuel is being delivered at the wrong times to the engine.

This one is worth a read...

Thanks for all the replies.

The garage has had it back in for a second chance (indy garage), I will take it to the local seat/skoda dealer to take a look pretty sharpish. I don't usually use them because they have had varying reviews and the nearest Skoda garage is in Exeter (I'm in Ilfracombe).

Fingers crossed that they can sort before any damage done

Once again thanks for the info!

Shocking! didn't know that they went so soon! Bora is on 80k and mates Polo on 105k...both 1.9 PD 130's and all on original bits!

Regardless of how quickly a DMF can fail, this is surely just TOO coincidental to be anything but timing fault, as result of cambelt change.

Since when does a DMF cause a puff of smoke on start-up?

I think this is what they want you to believe !

+1...too true! A garage tried to tell my dad the gearbox had gone on his T4....Turned out it was only the clutch bearings that had gone!

Sounds to me like they don't want the re-work, although I have heard of the DMF issues. HAve had some advice to replace with a std flywheel (as long as the torque is taken into account.

Am going on Tues to see the seat/skoda dealers garage. Will report back then.

Quite strange that Mike as my Dealer replaced mine under warranty at 34K with a solid flywheel and new clutch as was ordered by SUK.They stated that all 1.9,s with DMF problems will be converted to SMF.Anyway i agree with the driving and idling etc afterwards its so smooth and precise.Should all be like this from new

Sorry, can't agree. I had to have a new flywheel just before Christmas on my 1.9 TDI, mileage 44k. And the car's not driven hard, and doesn't tow anything. Once it started to vibrate, it was scary just how fast it deteriorated to a point where the job simply HAD to be done. I had a solid flywheel conversion kit in mine, and have since never known the car drive, idle and accelerate so smoothly.

The independent who fitted my new clutch and flywheel told me that his brother has a 57 plate Jetta 2.0TDI, and that had it's first DMF at about 13k, it's 2nd at 37k, and is vibrating again at just over 65k. The first 2 DMFs were done under VW warranty. So it's a known issue even at very low mileages.

My old mk2 1.9tdi had its dmf changed at 108k and had 117k on when i bought it. I drove it upto 158k without a problem. And i made full use of the engines potential.

Think it can boil down to driving style to be honest. A guy at work had a zafira 1.9cdti 150, and started having dmf trouble at low mileage 26k iirc. Turns out he was driving in too higher gear.

Im not stating that its your driving style, but i find 13k a little hard to take on board for a DMF.

Solid flywheel would be my prefered choice for replacement though.

Main dealer says timing issue, either pump or belt, garage said they will look again at it. Not much confidence in them now though. Fingers crossed.
