Stopped by the garage on the way home to grab a manual and heard a similar fan-like clicky sound. Having pulleys replaced tomorrow so will have a look at the FSR...

I honestly wouldn't worry, if it is the same noise I hear more a muffled whirring noise rather than clicking then it goes off after 15-20mins (leave a window down) go to car after 15-20mins and stick your head in, noise will have gone, if it is clicking you must have a different issue, my noise always comes from the area/vents near the temp air con controls on the middle console.....

Reason of the fan noise finally found and repaired
As it was rightly found the noise is caused by a small fan mounted behind the left hand vent in the climate control panel that draws cabin air across a sensor to sample the cabin air temperature.
I also pulled the climate control panel out and found that the fan accumulated dust and with moisture from the air it created a film of dirt on the rotary wheel of the fan you can not just blast out by using pressurized air (altho itīs good to blow out a dust from outside of the panel every 3 to 6 months). I disconnected and dismounted the whole panel, pulled out the electronic board with the fan and hereīs what I found: the fan wheel rotates horizontaly and the only force that holds its axle to the fanīs engine is permanent magnet, i.e. very small force. I assume that the dirt plus may be other things like bumps on the road etc. pull the wheel lower and it starts hitting the plastic back cover of the panel. Anyway - I cleaned the wheel usig a little brush, mounted everything together and the noise IS FINALLY GONE after 2 years. (...and yes...the fan runs ... I checked it  )My recomendation: - first try to blow out the dirt from outside the panel without pulling it out using pressurized air (it didnīt help in my case but youīll be surprized by the amount of the dust coming out). If this is not helpful: - pull out the aircon panel - the fan wheel can be cleaned from behind by brush without disassembling the panel - make sure the wheel is in the most upper position, anotherwords it is not in contact with the case of the panel I hope this helps.  ...thereīs some more news... The noise is back. This morning I sat in the car and checked the noise - no noise. So I was very happy. After driving it arround bumpy Prague the sound is back. The only reason Iīm able to come up with is that the permanent magnet is aging - getting weeker over the time and it is not able to hold the fanīs wheel in place. At this moment I donīt have solution to this. Last edited by Dan X5; 10-13-2009 at 11:33 AM. Reason: some more news...

funny thing, I was cleaning the interior of the car with air hose and put some air into the intake air slots, and the air noise started for me. I got scared and after hour of trying to find out what was wrong, i decided to put some air back into the air slots, and the noise disappeared.
I am thinking that i placed some dirt on the fan and the caused the noise, and the second time cleaned the dirt off the fan.
