Dual mass flywheel on Audi A3 2.0 TDI 140

[worlely]

Hi Guys,

i have a audi A3 2.0 tdi and ive been told that the dual mass flywheel has gone which apparently is really common?

its currently making a racket whether the clutch is held in or out, low rev range, makes the car shake, etc etc but drives fine when in gear.

ive been making do with it whilst ive been saving up the 1K to repair it, but recently its been very difficult to start - particularly in the mornings (cranking for 5-10 secs) and has been getting worse.

im not going to have enough money until the end of the month to repair it and will need to continue driving it, am i going to be causing any more damage by doing so?

and would it be the flywheel causing the difficulty in starting the engine?

thanks
chris

I reckon if you leave it you'll shag the gearbox bearings.

Don't see how the DMF could cause poor starting though.

I know it's a totally different engine but I've got a Passat 1.9 Pd TDi and I was told to replace the clutch and convert it to a single flywheel would be 450 quid plus the dreaded.

If your oop North it might be worthwhile giving Tameside Transmissions a bell

Continuing to use it will cause damage, the metal debris from the dmf will get into the starter motor and may affect the crank position sensor causing starting/running problems.

You will also be putting a lot of stress on the crankshaft.

Agreed on gearbox in long term. If the flywheel is wobbling about, could the starter motor not be making good contact with the teeth on the outside of the flywheel thus not turning it properly?

I have been running single mass flywheel on my diesel, and its wonderful for both knowledge there is no DMF to implode, and also for gearchange performance, and its lighter which means better spool up of revs.

The ring gear teeth are attached to the dmf primary mass, so they could not possibly wobble relative to the starter motor.

hi guys, thanks for the replies.

been driving the car today but no knocking at all.. weird..

any tips on the best way to be driving the car? just that ive been trying to drive softly, low rev but that's when the flywheel is knocking most, especially when slowing down.. so do you think i should try and keep the revs higher as this seems to work? only problem is i dont want to cause more damage by keeping the revs too high..?

ive heard some cars can be converted to solid flywheels, but no idea where the best place is to get them?
am i better off just replacing with a sachs DMF or try and find a solid? im looking to have the car for only a few more years tbh..

Google darkside developments. They have solid flywheel clutch kits which retain a lot of the oem characteristics of the clutch whilst being stronger and more reliable (southbend stage 3 I think is what they call it)

Your gearbox will be an 02M 6 speed, for info.

Looks a brilliant company - thanks for the heads up.

No worries, Tell Ryan Jason with the silver fabia sent you and I might get a discount on the hybrid turbo that I want to finally push my Fabia derv over the 300bhp mark.

hi guys, i have an audi a3 2.0tdi automatic s line 2004 and i been having a similar problem is currently making a rackle noises and the engine shakes when the car is on and not driving, it also rackles when the gears down shifts, and it also takes a couple seconds to start in the morning i been to a mechanic and he told me its the torque converter but i phoned up some people that recondition torque converters and they told me that my car doesn't have a torque converter, so now im just confused. this is my first time on this side, any help would be much appreciated.

Of its a dsg then it has a dual mass

[muli]

many thanks

Hi all

This sounds similar to the problems im having. Intermittent engine rattling noise, noise is louder when going downhill and when switching the car off sometimes. Any ideas how much it should cost to fix?

Not a VW but my son's Fiesta completely lost drive when the DMF went.
DMF's are expensive but obviously depends on how much time is needed to do the job
