Ours got to 194k and when i removed the engine the clutch had audi rings on it... Theres also nothing in the service history about a clutch change.
I think it will depend how its done its mileage, if it sits munching miles on the motorway, the clutch is being used less, so will last longer, OTOH if its always being driven around town, then the clutch is being used a lot more, and will fail sooner.
A new clutch is around £120, fitting might cost 200quid if your lucky. The other thing to consider is the condition of the dual mass flywheel. They do wear out, and if its dead its something like £300 for a new one.
As a result of this, when i did my clutch, i used a solid flywheel from an Audi 80 TDi, and a clutch from an early TDi A4. Flywheel was £35 and the clutch was £130+vat
