hi everyone my dmf is on its way out and dont like the idea of going smf heard to many horrer storys about it can damage gearbox long term so my question is what is the best dmf to get i have the fabia vrs blt engine code please help as i cant find any answers anywhere any uprated dmfs out there?any help is much appreciated.

Sachs DMF is the best replacement.

Hi Dave. My DMF and clutch will be getting renewed soon and I was also recommended sachs, but my mechanic told me LUK are slightly superior. Not much difference in price apparently.

Yes, superior because there's a better margin on LUK 

Seriously there probably isn't much difference between them but Sachs have a reputation to protect and their products are of consistently good quality.

They have also had issues recently with the SAC mechanisms failing and taking out the gearbox casings (part of the diaphragm spring breaks off, causing issues).

If going LuK you would need a 415 065 410 DMF and a 624 303 434 clutch kit. Also if the car is over 100k miles, then it's a good idea to get the injectors tested as well, and also have the front crank pulley checked (and replaced if need be, as it is a basic form of DMF) to eliminate any potential sources of vibration that could affect the new DMF. If it's a 6 speed, also get the garage to check the input shaft for play in the bearings. We have started to see a few where the bearings are wearing, causing an issue with the clutch systems.

Interesting octyal. I shall take this info on board. I'm all for preventative maintenance.

No problem. In my job we get a lot of calls regarding DMF's that have been fitted to cars to resolve a "faulty DMF", and it's only when we explain that you have to look at them as a symptom, rather than a cause, and the associated issues that can make them noisy, that the techs actually start to realise that sometimes it's not the DMF that's the problem. Essentially anything that can affect the crank rotation, will affect the DMF (short or long term - depends on the issue).

Think how an engine works, and it all makes sense. In an ideal situation, a balanced mixture of air and fuel is drawn into the cylinders, so you get a nice smooth power stroke from the engine. Now reduce the air/fuel (one or both) going into one cylinder, and you will reduce the power from that cylinder, leading to an imbalance in the crank, and increased DMF wear. A bit like getting cramp when riding a bike, you can only push the one side down so much, leading to a lurching movement.
