I'm about to have the DSG box replaced at the stealer. I've asked them if they recommend replacing any other parts while the whole lot is out in the first place. After all, it's a ten years (136.000 kms/85.000 miles) old car and nothing has been worn out yet and therefore not replaced yet either. I'm thinking bushings etc.

The dealer is obviously not keen on making money because I can't get an answer.

What do you lot recon?
(Please no DSG sucks comments and no questions about what a new DSG costs, and yes, it's a mk4 DSG.)

I don't know anything much about the mk4 dsg but you just as well get the clutch's changed while its out. Get the timing chain done to?

In the whole gear box the clutch packs and mechatronic are included.

Only thing I can think of is the Crank Seal, and if your feeling flush and your planning on keeping the car a while then i'd say do the Timing Chain whilst the gearbox is off.

As above, the timing chain really is the only thing id think about changing IF i was you. Im on 110k and have no intention of replacing the chain if its of any comfort.

Even bushes are easily acessable with the gearbox in place.

Not sure if MK4 DSG has a DMF but if it does I would change it.

I don't know the correct name for it, but we call it flywheel, not dual. Is it the same part?

The stealer are going to take a look at it, but it's probably not the source of my main problem.

 

[PaulW]

What is the problem?

 

[cuprabob]

Yes, it is the same part. The MK5 DSG has a dual mass flywheel and it's known to fail. As I said, not sure if MK4 DSG has single or dual mass. If it's being checked then you should be fine.

Got it confirmed from an Audi technician-friend of mine, the mk4 DSG uses a dual mass.

I found this link when I re-learnt the DMF abbreviation.

What is the problem?

A metallic rattling sound, much like the sound the shift fork makes when shifting from D to P, and back. (It's not the fork, it just has the same kinda metallic sound to it.) This sound is felt in the floor too.

This sound comes at steady intervals if in 2. gear or up, and the speed is low and the revs is low. It goes away if I step on it in 2. gear. To get rid of it in the other gears, I just press the left paddle and change one or two gears to get the revs up, but keep the speed steady.

The strange thing is, if I floor it in S from a stand still, it behaves as it should. No problem. (Sorry about this somewhat bad English sentences.)

Another problem is when I keep a steady pace about 65 mph, I get these dips in the revs. No more than 100 rpms, but easily detectable.

The VW techs have checked everything they can without taking everything apart. They've had communications with VW in Germany via the official VW importer. They've taken a lot of values from a lot of measuring blocks, but to no avail. The DSG has been resat, or what ever it's called.

The car got a new used mechatronic in 2009. But that doesn't mean anything.

Here's two clips. A bit hard to notice the first time you listen, because of the lovely exhaust note.

There is no special (flywheel) noises when idling.

This "phenomenon" is almost not present when the car is cold. A lot more present when the car reaches the optimum working temperature.

and if your feeling flush and your planning on keeping the car a while then i'd say do the Timing Chain whilst the gearbox is off.

If I ought to do the timing chain, I will definitely NOT feel flush afterwards.

Did some price checking.
