Its a very common problem for Audis.  So common, in fact, that the 
replacement sensor has had its price reduced to around $5 or so with an 
o-ring.  Its also a fairly easy DIY replacement (the technique was just 
posted, IIRC).

The other option is a sticking thermostat.  However I had that problem and 
it behaved rather differently than you described.  It would basically heat 
up to one mark to the left (cold side) of vertical and then stay there 
unless I drove the car really hard or sat and idled for a while.

The thermostat is much more difficult to replace on the 2.7T than the 
coolant temp sensor is, so start with the sensor and see if that solves the 
problem.
