Re: Early Twinair DMF failure

Just to add to the thread my 105 twinair has had DMF failure at just over 37 k. the dealer has never seen one before. It does seem rare tbh.

Re: Early Twinair DMF failure

Hi all, just a quick update in case this helps anyone else who encounters the same fault. Fiat / Alfa came back with an offer of a 30% contribution to the repair, stating this was a take it or leave it offer.

After a written complaint with support from the dealer ( who themselves have done two other low mileage DMF replacements this year) , they came back stating they will cover 100% of the repair.

Final items needing replacement due to the DMF failure:

DMF
Clutch
CSC
Bellousing

Feels like a new car following this being done, was obviously getting worse over a period of time before finally causing gearchange problems.

Re: Early Twinair DMF failure

I would think In these little cars with very little space under the bonnet, the DMF needs to be small, the smaller it is the less resilient it will be.

The main reason these have become mainstay in almost all modern cars is because they dampen vibrations from the engine into drivetrain and potentially the rest of the car, it’s another way to help decrease cabin noise and make driving the car a bit more relaxing.

Re: Early Twinair DMF failure

Is it undersized though?

The flywheel on my 3 series has to put up with 380Nm of torque, diameter? 240mm.

Twinair 500/Mito/Punto puts out 145Nm and the diameter of the clutch is 200mm.

Canít be bothered doing the maths right now, but Iíd say the clutch and flywheel probably arenít undersized. You expect a certain amount of failures, this is one of them and thankfully Fiat are doing the right thing.

Re: Early Twinair DMF failure

HELP!

Im trying to diagnose a possible DMF failure on a 2010 model fiat 500 twinair with 85 PS

What did it sound like as it was failing?

@Charlie1989

'Standard diesel' DMF failre is a CHRP as you turn the engine off.

From the unsupported elements flailing around..

There was a panda trekking with failure at 10k on here a while ago.


I'm sure it is brought on by abuse..as contamination shouldn't really be relevant.

It does make a small noise when you turn it off as the engine comes to a halt but that sounds more like the engine spinning backwards for about a quarter turn

What is a CHRP sound?

Im having a loud rumble while accelerating in 5th gear under 2200 rpm with the wheels straight.

I cant decide if it is more likely to be engine mounts or DMF with 68000 km on the clock..

I am not aware that the early Euro 5 TwinAirs even had a DMF!

There on the Euro 6 engines from late 2013 500s

Does the car make the noise in 4th gear?
More likely a gearbox issue, if only happening in 5th gear!
I donít think there is a DMF on this model year

Yes it makes the noise in all gears, its really only 5th where you are at low revs for long enough for it to become annoying..

Its a loud rumble that you can feel in the floor..

I gave the driveshafts a good strong wiggle and there is no noticable play.. maybe very little on the longer shaft..

A 2010 FIAT 500 TwinAir 85 doesn't have a DMF.

Thanks for that information, im down to dogbone engine mount or driveshafts, but im betting its both.

The rumble depends on the steering angle and there is a tiny clunk as well.

Im betting that it is not wheel bearings after 68,000km..

Re: Early Twinair DMF failure

Hi, Iíve just experienced total destruction of the dmf,clutch,clutch release bearing and the box shaft itself. Itís on itís second box which was replaced by fiat within the year when it was new in 2014. Itís now a right off basically,gutted isnít the word. What to do..... the car broke down by a garage,they have stripped it and one of the guys said he knows of this problem. To which Iíve trolled the net and sure enough it seems a common problem. Problem Iíve got is obv the garage want to be paid for the strip down and Iím looking for a solution,Iíve found refurb 5speeds on eBay etc,but now the garage is kinda pushing me to them supplying. I just want shot of the car now. They are quoting 2000 plus.
Spent hr on the phone to fiat Uk who just wont play ball. I give up !!!

Re: Early Twinair DMF failure

Hello and welcome to the forum.

So very sorry to hear it's in such sad circumstances. I can understand how gutted you must feel.

Unfortunately the garage which currently has possession of the car has you over the proverbial barrel. Either you pay them to fix it, or you pay them for the work already done and have the car trailered away someplace else. I don't see how they could reasonably refuse to fit a replacement 'box supplied by yourself, but they'll likely load the labour charge and obviously won't then warrant the replacement 'box.

Most folks in similar circumstances have reported that Fiat will do little or nothing to help; pursuing that is more likely to lead to more frustration and anger than to achieve anything useful.

DMF's are a wear and tear item, but sadly on the TA they can cause quite a bit of collateral damage when they let go. Stories like this just reinforce why I'd not personally want to own a TA once out of warranty.

Pragmatically, I'd get it fixed as cheaply as possible and then quickly trade it in. Who knows what other components have been stressed? Paying £2000 and then having the inevitable fight for restitution if the repair doesn't last isn't a place you want to be.

If there's a lesson here for other TA owners, it's not to ignore any symptoms of excessive DMF wear; fixing it before it breaks something else is likely to prove considerably cheaper than waiting until it's failed completely.
