Na there are no diagnostics for the operation of the clutches them-self. The clutch actuators are monitored to make sure they don't go down past a pre defined point which would let the computer know that the clutch is low on material but that is not the issue that is happening here.

With our clutch problems the actual clutch material is becoming soft and been ripped of the clutch and in some cases getting stuck to the dual mass flywheel due to excessive heat (climate?). this is leaving glazed and elevated spots on the clutch which don't transfer torque correctly and thus the slip/shuddering, but the clutch hasn't compleatly been worn down all the way.

There is a sensor that monitors clutch temp but I have only seen it throw up an error on some cars, on mine it didn't.

For them to check all they have to do is remove a black plate that covers the clutch housing and physically check the clutch...

Does anyone know if you connect to the car VCDS whether it gives you the report / analysis of the Clutches and whether they are within the tolerable operating range?

Or is that some other fancy pants mystical VW analysis machine?

While I was at the dealers, they did have a graph with the tolerance for each of the gears. So yes, they did use some sort of computer to monitor the clutches, but I don't think it's just a VCDS thing.

Hence why mine showed perfect clutch operation yet was still throwing the fault code! They tested it and because the clutch actuator was jammed the plungers still moved along the full stroke.

Unfortunately, my wife managed to make it shudder again this morning

New clutch needs to be bed in with the flywheel all over again, meaning no aggresive driving, sudden acceleration and hard launches for the first 1000km?

Fly wheel is separate on the DSG, the drive plate between the clutches is the part that causes the shuddering.

For a conventional manual that might be true but you are more likley to get more clutch slip with less aggressive driving becuase the DSG works the opposite way to a manual. The pressure plate pulls the clutch off the drive plate, not pushing it on.

Well, I haven't been able to replicate the issue...so no point taking it to the dealer to demonstrate something I can't do on demand. It did only happen the day after the fix...but as long as as it doesn't happen again, I'm happy.

After having the ventilation pipe changed to reduce oil consumption, I have noticed on cold starts, the engine is very rough and shakes quite a bit. This never happened before I had the pipe installed. Is this related or just a coincidence and I have more issues on my hands?

The Polo is going in for repairs on the 21st so I may as well find out all the issues before it goes in.

Not sure if its related to the pipe (Hard to see how) but after install of new pipe (1000km) mine started idling rough then a ticking noise from the engine and check engine light not long after. I scanned it before going to the dealer and got a low fuel pressure fault and something to do with the FPR. They diagnosed a high pressure fuel pump issue but after replacing still had the noise. They then tried to just get the engine replaced on oil consumption as it would be easier then pulling it all apart to find the noise and fix when it may have been a oil problem that caused it, and to fix then have to replace again when it became the engine would waste time but HQ said no. So now there pulling it apart. Still waiting to find out the issue. They did overfill the oil when I had the pipe done but hard to judge if it was enough to cause damage.

[Zakarados]

Damn it, just give me a new car!!! I will tell them about it when I bring the car in and see what happens... I will also be doing a consumption test after they fix my rear bumper....

same thing has happened to my wifes polo tsi has happened twice and on clear streets. Have just had a trip to Harvey BAY CAR WENT LIKE A DREAM 5.5 LTRS PER 100KLMS. Have'nt had any rattles in the engine now done 8500 klms. Will keep my eye on this problem. Have had to have windscreen wiper motor replaced and rattle in drivers door that they can find but thats it

They do a software update as well as the pipe if they do the job properly....

watching megafactory. Veyron at wide open throttle = 3mpg. Range = 12 minutes. Staggering. What I dont understand is how Volkswagen can build a DSG gearbox that can reliably handle 1000hp but they cant build one that can reliably handle 100hp.

Even 1200 bhp in the SuperSport!

The gearbox is built by a different company than the normal DSG's and I'm sure is much much much more expensive.
And it's wet-clutch. They tend to have fewer issues than the dry-clutched ones in the Polo.

Any photos to illustrate? The clutch set is replaced as whole assembly, what items are in this set? I am going back to ask for replacement under warranty soon.

The clutch pack is a riveted assembly containing the drive plate and both clutches. The kit also contains new actuators and a selection of shims to get the right gap conditions for the clutches. This is what the kit looks like:
