Took my Superb in last week with noise coming from the clutch.  Collected it today and took it straight back.   Current bill (parts, no labour) was around 2000 EUR (thankfully still in warranty) and at 111,000km (around 75,000miles?).  Drove it back to work and there was still noise coming from the clutch so took it straight back to the dealer.   Repairs so far:  replaced clutch pressure plate assembly, replaced clutch disk, replaced flywheel, replaced clutch housing.
