Howdy.

My parent's 1 year old yeti (CR110 4x4) broke. Diagnosed as the DMF falling apart in situ. Repaired under warranty by Skoda quickly without any issue.

Two questions:

Is this a common failing?

And anything they can do to prevent this happening again?

DMF's are a rubbish on all cars not just Vag group cars

Maybe it is the way they are used? Not wanting to cause offence, I do a lot of miles and none of my cars have had a clutch, DMF or otherwise fitted in the usual 140k miles over three years.

How many miles has the car done, is it all hill starts, towing or stop start type driving, there must be a reason why they fail

On modern cars the DMF is unfortunately an expected cost down the line. It's a consumable.

I've heard they usually last at least 50k miles. Usually....

But they can last a lot, lot longer, like 100k+

Thats the first on Briskoda that I've heard about in 2 years.

Just unlucky I think,but at least it's dealt with under warranty.

And the first instance I can think of here, so no, it isn't a common a problem.

Honest John has a page on his website http://www.honestjohn.co.uk/faq/dual-mass-flywheels/

But no Skoda's were mentioned.. So no it's not common

Cool, thanks guys.

Car's done less than 12k, driven gently, no towing, no huge amount of stop start driving or hill starts.. Probably just falls under the '**** happens' category.

And the first instance I can think of here, so no, it isn't a common a problem.

Likewise not heard of a DMF failure on a Monster; probably just unlucky and got one with a manufacturing defect; does happen. A 110 4x4 being used by a press reporter had a catastrophic failure of the Haldex box. Turned out a cotter-pin had been missed out during assembly

Always think it's best to try keep some form of load on a diesel engine and try not to drive in to high a gear to early. Need to completely ignore the gear change indicators requests for a higher gear; it asks far to early, only respond to down shift requests (can get that on a hill climb).

Sometimes get caught out myself and drop it into to high a gear to quickly ; tend to try stay in 4th into the low/mid 40's and 5th to almost 60.

Modern diesel autos also have DMF's.

I had two go on my previous Octavia, one at 35k and another at 80k which broke up and took the gearbox out at the same time. Both times the clutch plates were barely worn so the dealer said it was just unlucky and probably bad manufacturing. Had really bad vibration on setting off from new so I reckon there was some other fault as well.

Latest Octavia still going strong at 75k without any problems.

Yeti is OK but it's only done about 5k so far. Perhaps most Yetis haven't yet done enough mileage for it to become a problem.

I was told when I had all the Octavia problems that it is possible to get a direct replacement flywheel kit without the DMF so if it happens again I'll be looking into it. Never seemed to get any vibration problems on the Fabia VRs or the Passat Sport we had before.

I have heard that it's a problem with some taxi drivers where they do a lot of stop start in traffic and set of at tickover. This apparently puts extra strain on the DMF causing early failure, so it seems it's  best to give it few revs when setting off. Still seems to be a major design fault to me though if they can't get it sorted after all this time.

Of course it's not to make money is it.

But no Skoda's were mentioned.. So no it's not common

But it does mention VW golf diesels, isn't this the same lump as used in the 140 & 170's?

No.

The Honest John report is for the previous engine, as far as I can see.

Excuse me,but what does DMF stand for?

Excuse me,but what does DMF stand for?

Dual Mass Flywheel.

It's basically two flywheels joined by springs, the intent is to reduce vibration with less mass than a conventional flywheel can. Particularly for low engine speeds. They work well but do wear out and sometimes break.

Dual Mass Flywheel.

AFAIAC, most clutches have had built-in torsional vibration dampers for a long time. Thye difference with the DMF is that the torsional damper in the DMF is built int the flywheel, instead of the clutch plate, so there is a tuned mass to work with.

All torsional dampers suffer from weakened springs after some time, but why the DMF should be any worse than any other construction is beyond me. Maybe operator clutch technique may have an influence?

. Maybe operator clutch technique may have an influence?

I have several times stalled my Yeti when pulling away gently and not giving enough revs (I am new to diesel engines) and there is quite a loud clonk as the engine stops dead. I suspect that this is caused by the DMF operating with the 2 halves moving independantly.

What do others think and what is your experience of stalling?

I'll admit I have stalled mine a couple of times recently - the engine map appears to be a bit different from other cars I drive or have driven, because I NEVER stall! Usually it is in stop-start traffic and crawling forward on a light throttle.

I have also heard it said that cars with the stop-start technology tend to mash DMFs due to the constant stopping and starting of the engine.

I had one replaced on my last car - a Volvo V50 2.0D - in fact in the end I had to have a new flywheel, clutch, release bearing and slave cylinder thanks to some ham-fisted technian(s).

Does the DSG version have a Dual Mass Flywheel?

Does the DSG version have a Dual Mass Flywheel?

Yes

In my PD140 2.0 TDI DSG octavia I had to have mine replaced at 80,000. No damage to rest of area though. Just worn out. (2006 model.)

How will the auto help if that also has end?

Are DMF just fitted to the diesel due to the higher torque output or would for example the 1.8 tsi have one?

DMF's seem to be fitted to diesels to remove some of the vibration.

 Hi. This is a problem I am having with my Yeti as you can see they blame it on driver style, similar to what Daily Telegraph Honest John says they do. Just got the car back with a brand new clutch, guess what the same problem exists and the car is going back in next monday, so will it be another clutch after only doing 8 miles from the garage to home. By the way I didn't pay the bill the lease company have paid and also registered a complaint against Skoda.

 

 

I have a Skoda Yeti 2.0 TDI SE which is a lease car. It is less than 12 months old with 13,000 on the clock. From new I noticed a  rotating tick over noise which I thought was just the noise a Skoda diesel engine made. I took the car to the Skoda dealer in Bournemouth for a heated wing mirror fault, but informed them that I was concerned about the tick over noise which seems to be getting louder. Instant diagnosis, it's your bad driving, it's the DMF that needs replacing you will have to pay for it, or we will charge the lease company, who will then charge you. This is just the start, I am waiting to see what they come up with when they have carried out a full examination. Has anyone else had the same problem? This is the reply I have just received from the garage

 

 

                Hello Geoffrey

 

                                                As you are aware your vehicle is in for a clutch repair today. The garage has removed the transmission assembly to gain access to the clutch. The clutch has been removed and inspected. After a long conversation with there master technician, he confirmed there are no manufacturers defects, the noise and low clutch pedal travel are caused by premature wear.

                                                I have called Skoda UK, they confirmed there are no issues with clutch failure on this model, they have search on this model and no other issues exist with clutch failure.  

                                                As the clutch has worn prematurely we are looking to yourself for the cost of the repair. Please confirm you accept £504.32 + vat as a recharge. Should you wish to dispute this, we can instruct an independent engineers to inspect the vehicle and create a report.
