Air con electrics (B5 S4)

[jeffw]

My aircon doesn't work at the moment. The system is gassed and the Aircon pump is working if you apply 12v to the supply for it. Fuse is OK. Ambient temp in the DIS shows what you would expect as far as external temp is concerned.

Question is...

What else should I check (other sensors and/or relay ?) and what other actions can I take to rectify this ?

[shineydave]

have you tried going through the built in diagnostic mode?

[grizz]

there is a pressure sensor in the drivers side of the of the condenser , if this shown it's low on pressure it wont allow the pump to work .

Here's the link to the codes and how to access them, was on the house pc earlier and didn't have the link in my favourites
