Hi, I have a 2002 A6 1.8T avant and the aircon is blowing cold when the car is moving and heats up when i slow down or stop.
The air con gas pressure was also very high so I was advised to get it regassed -it was done 2 years ago so i thought it was time to get it done.
The air con is still the same after ther regass so I went to see an air con specialist
He stated over the phone it could be the pressure sensor or the cooling fan that is at fault- on going to see the air con spec' he quickly checked the fans and said the viscous fan was at fault but then also said the electrical fan could be faulty but would need checking.
1) I would like to know if anybody else has had the same problem with there air con system and what corrected it?
2) I've never seen the electrical fan turn on - when should it turn on?
3) if the viscous fan is faulty (but still turning) could this cause the above?
4) Last of all where is the air con pressure sensor/switch located?
Thanks for reading
