    DMF = Dual Mass Flywheel. You shouldn`t accelerate diesels in 5-6th gear at 2-2.5K rpm as the torque produce can damage the DMF internals which will cause the car to vibrate all the time.

    but it dont do it before 2 thousand revs and stops after 2and a half .so how can that be then? you drive at that on the motorsway , your not really accelerating at that just cruising if you know what i mean

    I have the same problem with my 05 1.9TDI at 48K... It's noticeable to the driver but passengers are not aware- YET! :unsure:

    DevonMikeyBoy: Why the hell can't i drive my car at mid revs without it breaking!?!? That's ridiculous! Where in the user manual does it say that
    "this Audi is incapable of being driven in 5th and 6th gear where you would need to accelerate or overtake in the range of 2K -2.5K revs or it will break!" Surely if a DMF can't last more than 40-50K miles than they should use a normal flywheel?


    Tell you what, I’m loosing faith in Audi with all these build quality issues. I bought this A3 used with only one owner who covered under average mileage (38K when i took delivery). Within 3 weeks the engine failed which was covered under warranty... then the steering rack... and now my DMF!

    I love my motor but it's just not acceptable from what should be a quality manufacturer!

    I have to agree with Paul C. I wasn't given an introduction to driving Audi TDI's. I haven't read the manual either but I am sure the 2k to 2.5k is not an odd speed to be accelerating at in fact in six gear at 2.5K I would guess that is about 60MPH? I've not checked and that's only a guess.

    I have had the DMF and clutch changed on a 2005 2.0tdi 65K and still hasn't fixed an issue with the car. Maybe I was ripped off, maybe Audi's are rubbish (But I still love her). I won't be buying another that's for sure.

    y don't we all go back to audi and make them sort it ! as it seems a common fault , i have had golfs for years (still got one with 164000 on clock ) and never had a problem then i sold my scooby, what never let me down so i went for a audi as they are supposed to be as good as vw , its these little things what **** you off and only had it 2 weeks:think:

    Bearder. I have been advised that the flywheel may have been responsible for knocking the gearbox which has cause my current problem. He did ask if there was any virbration when in 3rd gear, which I don't have.

    Oh. I tried my car at 2.5k revs will put the car at around 80mph probably more. What are you supposed to do drop it into 4th? Not sure what the devon boy was referring to?

    Is this for real?
    My car sits at 2k rpm in 6th @ 70 or thereabouts, so accelerating from 70 in 6th will damage the DMF?
