I've just managed to fix my air conditioning, couldn't find much info about the location of the pressure switch, so I thought I'd post up a thread. It's a 2.0l diesel estate model.
Since I brought my car the air con hasn't worked. The "econ" setting was permanently engaged, even if I try to select "auto" it toggled back to econ.
I took it to be regassed, and much to my surprise it actually had the right amount of gas in it, however it was throwing up a high pressure fault code.
This suggests it was the ac pressure switch. I couldn't find much info on the location, but on an audi a4 they were behind the headlight. Some people said you needed to remove the bumper, but I managed to get the headlight out without that (although my bumper does have a bit of damage, so maybe that helped).
I forgot to take a before shot, but the three torx screws under the arrows hold the headlight in.
The circled screw is for the bumper, I loosened the 3 on top of the. Grill to give a bit of play and the whole unit came out.
With the unit out the pressure switch is easy to locate.
If you've not done one before the plug comes off and the silver bit unscrews. There's a kind of bayonet arrangement, so you don't loose your gas. Seal is via a little o ring.
The only negative to the story was the cost of the switch. The only place open was ecp. The switch on their website was £36. However, they didn't have that one and sold me an alternative for £66. Even though it was the same make, they wouldn't discount it down. I probably should have just ordered a £10 job from amazon, but it's a bit uncomfortable without ac at the moment!
