Im getting an intermittant knocking at idle, worse when air con is on, also have a slight judder when pulling away in 1st gear. Car has had new clutch just over 12 months ago, ive got receipt for a Sachs pressure plate and a Sachs organic friction plate. Looks like they have dont the clutch without replacing the DMF :-( Im prepared to have the DMF changed but should i do anything else whist the box is off? Slave cylinder? Any help much appreciated

 

Also is there a way to diagnose faulty DMF without taking the box off?

Is your car a Mk1? I wasn't aware a 1.8T version of the vRS was produced in the Mk2. 

No MK2 TFSI mate, havent updated my profile yet lol.

Low engine speed (rpm) and high gear.

 

Hard acceleration.

 

Doing this you'll soon know if it is the DMF.

 

If it judders (or feels like the clutch is slipping) then it is very likely down to a worn DMF.

Well, on the diesel you can take the starter motor off and move the starter ring on the flywheel with a big flat blade screwdriver. If it moves more than an inch or so, the springs in the flywheel are excessively worn and could do with replacement.    

 

I'm not sure if any of this applies to the TFSI. 

Thanks for the replys lads, will try both tomorrow

I have exactly...and I mean exactly the same:

- if i turn off aircon the knocking dissapears 90%

- if i try to pull away in 1st at low revs it judders (same when reversing), but revving to 1500+ results in no judder

 

I'm also guessing it's the DMF, however there's no juddering whatsoever in other gears, regardless of gear (and as I just got the stage 1 chip-tuning today I HAVE tried it all :p).

 

I personally don't worry about it...when it will eventually go I'll simply replace it. 

Sounds like we defo got same prob. Mines the same doesnt judder in any other gear and drives fine normally. Ive learnt to rev that bit more in 1st to avoid the judder. Ive ordered a dmf anyways its annoying me and dont want to risk it going completly, fingers crossed!
