Just an update on my issue. The cylinder was misfiring and the garage put in a new coilpack and seems to have fixed the issue. 

Hopefully this helps someone.

Sounds about right, it's a shame you didn't start your own thread about this rather than posting in someone else's, I certainly didn't spot your problem nestled in a thread about a failing DMF on a VRS.

There's always next time though...

Okay so I have had my HG checked and it was the radiator leaking slightly. This problem however is apparently the DMF . You guys are always on the money it's unreal. Just thought I'd give you an update.

 

Thanks again,

Tom Jones

Quick question. How would a garage check for DMF wear? Because if its not that, I really can't afford to pay £1000 for the wrong part to be replaced.

DMF cannot be checked without removing it, it will be noisy off idle and the car will judder when you pull away unless you rev it harder and slip the clutch more.

It's just the garage that said it was DMF wear hasn't actually removed it. So im concerned it may not be that and they're trying to con me. It doesn't judder from start off but I do have a vibration through the steering wheel and the accelerator pedal when revving at idle or hard acceleration, nothing much through the clutch pedal though which is what's concerning me

Then I would ignore the garage, fixing the radiator is somewhat more important than the DMF which may get worse or may not, generally no-one replaces the DMF until the clutch needs replacing.

The clutch is fine, no slippage to note at all. But if I leave the DMF, won't it break up and ruin my gearbox?

Absolutely not, who told you that?

I think i read it on mkiv golf forums a little while ago and when the garage said the dmf was on its way out, alarm bells were ringing. So nothing will happen if it is the dmf other than an insufferable amount of vibration? 

Nearly wrecked the gearbox on my Octavia MK1, I had only owned it 3 days and had not felt anything untoward vibration/clutch wise but I did notice the engine shaking and on start up a couple of times almost like it was kicking back, this shaking sheared one of the drive straps linking the clutch cover plate to the ring that engages with the friction material, the now loose piece swung out and started gouging its way through the bellhousing.

 

Clutch operation was then awfull and you could feel and hear the scraping, drove it maybe 25km to workshop and was very lucky to save the gearbox.

 

The DMF was worn and I believe it allowed the shaking which caused the damage but it only had slightly more movement than the new replacement.

I have also heard of broken crankshafts caused by DMF failure.

More catastrophism than you can shake a stick at in here.

J R are you actually trying to help the OP?

Hadnt even read the thread so dont know what the OP was seeking, I was simply responding to an incorrect posting.

In all the years on here I have never seen a post about a DMF breaking up and wrecking a gearbox and there have been hundreds of DMF failures, the clutch will generally fail first giving the opportunity to replace the lot, if the OP's clutch is ok then the DMF will also be ok.

This isn't about who's right, it's about helping people and the scenario you describe is so unlikely it might actually be unique.

Okay, so this is confusing. I guess, I can either spend £1000 then or risk losing further expensive components. My only symptoms is...

1. A strange squeaky noise from the DMF area when cold and idling which disappears once i engage first gear, clutch still depressed.

2. Vibration through the accelerator pedal mostly which intensifies and fades through the rev range 1500-3500 and can sometimes vibrate the dash to an audible note

3. A intermittent rough idle

4. The 50/50 chance of having difficulty starting on cold mornings, once warmed the engine up it starts fine.

 

I've been told dmf or injectors but the dmf apparently has wear, that's all i know, whether its true or not is another thing. Any thoughts to help clarify my specific situation would greatly be appreciated. I've shelled out £1,200 since 11/2018 already and don't have the funds for another £1000 if its not that.

 

Many thanks,

Tom Jones

Sorry but a Dual Mass Flywheel can fail in a bad messy way. I've seen two major failures:-

One was a Mondeo where the gearbox/bellhousing was a write off and as the car was old it wrote the car off -

The other was a Saab 93 where the gearbox was repairable.

 

When you understand what is inside them you can see why. Lots of cogs and different strength springs. The springs eventually become weak especially with very tourquey engines (this is why many petrol’s with DMF don't have issues) or where cars are parked for long periods with springs permanently under tension.

 

HOWEVER:

• The squeakey noise may simply be the release bearing which may be fine for years
• Check the engine mounts - especially the one on the top of the gearbox (rock backwards and forwards - I've had one go before)- known to fail an pass on vibrations. NB Usually DMF issues usually go away as the revs rise. The pd engine is usually reliable but is a rough old thing so you'll know about it if an engine/gearbox mount has failed.
• Intermittent rough idle - can be all sorts of things on a pd - eg injector wiring loom causing an injector not to work on a cylinder (or two!)
• re 50/50 being able to start - something else eg glow plugs, tandem pump etc (Have you had any codes read?)

 

Some of your earlier syptoms way back when on this thread did sound like DMF though.

 

Hmm second thoughts re " difficult selecting gears sometimes like the box is knotchy as hell and won't fully engage gears sometimes " - OK check the engine /gearbox mounts as when the gearbox moves it changes the way the car goes into gear and vibrations increase. My money is still the one between top of gearbox and chassis. Sometimes hard to spot its failed however usually easy/cheap fix if bolt can be undone!

Ah but unique major failures should not be mentioned because they can provoke  catastrophic catostrophism reactions, unfortunately I did not know this and the one I generated has already spread to another thread.

 

My next door neighbour has just has his gearbox wrecked on his MK2 FL 140tdi by the clutch diaphragm fracturing and cutting its way through the bosses on the gearbox casing, he felt or heard nothing until the oil was dripping.

 

Garage replaced gearbox, clutch + DMFwhich had covered few miles, they said the DMF had cause the failure, I'm not so sure as its a known fault and I had told him to keep an ear and eye open for problems (learnt from this forum) but having seen the violent torque reversals that my failed DMF allowed to happen (which no doubt caused its failure) and seeing that they could fracture the clutch pressure plate drive straps it certainly could hasten the failure of a clutch diaphragm with incorrect hardening and stress raisers.

 

But hey, 2 neighbours both owning silver Octavia Estates, both having DMF and clutch failures causing gearbox damage (I terminal) is so unlikely as to be unique, you could not make it up except I just have.

This is a know failure of the Sachs clutch cover plate with the CR 2.0 diesel:-

So judging by my latest list of symptoms, its not sounding like DMF failure?

I'm just saying check the engine mounts as they can casue havoc especially re vibration AND gear selection as it puts the linkages out of adjustment when the engine moves. Try rocking the engine backwards and forwards - be warned even when failed it's sometimes hard to spot!

 

To be honest if it had been DMF back in 2016 I would have expected it to probably have failed by now! However worried about another post "When I start the car in cold weather, whether that be in morning or at night, the chatter noise is loud and clear" - does it still do this?

The engine does shake quite violently when it idles rough but i very rarely get the gear selection issue now, its still knotchy occasionally in lower gears but nothing too major. To be honest, I was banking on a new clutch/dmf kit fixing the rest of the problems. Are all the things you suggested in an earlier post easy things for a garage to check?

So not a Mondeo, Octavia or Superb but a VRS in drag, what does it all mean?
