VR6 cams on corrado
Discussion
I was just about to suggest that you post on here seeing your post in GG.
My VR6 doesn't have noisy cams (I've never heard noisy cams but I reckon I'd be quick to spot an odd rattle).
Mine has just short of 150,000 on the clock. I change the oil every 5,000 miles (got the VR6 at 113,000 just over 3.5 years ago).
I'd avoid VW main dealers like the plague. I'm sure any respectable garage will be able to diagnose the fault, though it might be tricky if you don't leave it with them so that they can hear it when starting up from cold. If yours is in for a service it'll no doubt get a thorough check. As others have suggested timing chain should be looked at at 100K.

Piston slap is common on VR6s but hardly discernable to the layman.
Its more likely to be lazy hydraulic tappets. This is no big deal- they just need a few seconds to pump up. It doesnt damage the engine and sounds worse than it is- it's a good way of trying to bargain the price down of a potential purchase.
You could spend ages taking it apart and dismantling and cleaning the tappets and the noise would probably still come back.
On my Porsche 928 S4 I used to own, I would hold it in a low gear and give it some revs for a little while the night before- when the engine was warm.
The following morning the hydraulic tappet noise wouldnt rear its ugly head- probably because the little oil ways that supply these tappets were blown clear.
Its just one of those things and particularly bad on VWs.
Next time you change the oil- you could engine oil flush it- but its not worth taking the head apart for.
