It's a common problem, it's one of the stepper motors for the air vents, they click every 7 minutes when they're stuck or broken.
It should throw a fault in the system if you have it scanned, if I remember correctly there are about five little motors, VCDS should tell you which one is making the clicking sound, and that needs replacing.
The manual says
Quote:
Replace the actuator motor if it makes clicking or rattling noises in regular intervals (approx. every 7 minutes).
These noises originate via activation of the actuator motor via the A/C control head -E87- in actuator motor drive.
Activation occurs to maintain the flap/motor securely in one position.
