Thanks for your reply.
Most people say that if A/C high pressure sensor  clicks too often, it's   
caused by not enough gas in the A/C. How often should the A/C be   
refilled? Is the any other way of testing the amount of gas in the A/C.

Clicks are the high pressure sensor activating or deactivating. R12
pressure falls below threshold sensor is set to, it clicks, compressor
goes on, engine seems to lose a little power, next click says R12 is
sufficiently compressed, so compressor switches off and engine regains
power, R12 gradually loses pressure, pressure falls below threshold
sensor is set to, it clicks, compressor goes on, and so on and so on. My
'90 CQ does the same thing.

 Gday again Audi fans.
 When I switch the aircon ON, I can hear clicks coming from the
area of
 glove box, click repeates every 15 or so seconds, and at every
second
 click engine looses little power, then it gains back the power
at the
 following click. Apart from that the A/C seems to work OK.
 What might be causing that? Any help will be welcome.
