Mk 4 Golf GT TDI 2001 - Head Gasket or garage trying it on?

[Sideways Rich]

Evening All, Sisters car was in at the garage today for a service and she got a call informing her that the head gasket needs replacing?!
Here are the symptoms;

<> Leaking Coolant (went through a bottle within a day)
<> Over-heating
<> Car has done 106k miles

If the collective wisdom confirms the garage's view what is the cost (VW specialist rather than VW main) to replace the head gasket?

Could be the headgasket unless there is a wopping great hole somewhere for the coolant to leak from.

I would have thought that that much water leaking through the head gasket would have been pretty obvious as water vapour through the exhaust! It could possibly be a leaking radiator or leaking seal somewhere - ie water pump or similar. Loosing all the water would make it overheat!
