2011 A4 Quattro 2.0L... this video was a lifesaver for me. 15/16 deep socket to remove/replace, 15 minutes of work and $88 at O'Reilly and I have ice cold air again.
Just had my A4 b8 ac gas recharged, nothing, not cooling at all still, workshop wanted 180 euros (on top of the 80 I just paid for the gas) to 'repair' the aircon, found your video and ordered a new switch for 58€, it arrives tomorrow, I'm hoping and confident that you just saved me 120€ or a sweltering summer on the Costa del Sol 🥵 thanks for posting, I'll let you know how it goes 👍🏻
Hay mate, thanks for sharing. Daughters A4 B8 AC stopped working at 1100, did a quick search, found this video, brought the part, chucked it on and was working by 1200 👌🏼.
Looking at the comments, there are so many people saying different things and have a different interpretation of "AC NOT WORKING." Can you explain what exactly were your symptoms? ...is the AC Working but blowing hot air.. when you say NOT working..so people are thinking there is no air coming out of the vents when you turn it on, that's what Not working sounds like to me.
hey brother, thank you. i just bought an a4 and am missing the switch. but i am also missing the little piece that it screws into, do you know where i should look to purchase it?
Hey mate my air con blows cold air when im just cruising around but during higher rpms normal air blows from the ventilators instead of cold air will this switch be able to fix it?
@Benson Yun. Sure! Here's a reworded version: I own a 2017 Audi A4, and I'm having trouble with my AC. It doesn't switch to the 'On' position; instead, it only defaults to 'Off', and the rest of the options are greyed out besides the Off. Occasionally, the AC does turn on and cools my car, but sometimes the entire AC control module doesn't work at all. I've already replaced the AC control module, but the same problem persists. Can you please help me?
If the module has been replaced, read the vagcom, 9-10 times it's going to tell you where the exact issue is. Most of the time it's pressure switches etc..
I have a 2011 B8 2.0L....the ac won't work....we did a diagnostic, also changed the pressure switch, still won't come on, also had a look at the bcm...any advice guys..Thank you

@@sheazadhussain1500 In my case the AC light was on, but the compressor wasnt working so i got no cooling. Maybe you have a different model.

Tried to recharge my AC, and the low pressure valve read 95 PSI. The recommended range is like 30. Could this switch be the problem? Or is my compressor shot?
This is happening with my 06 a4 as well. AC turns on and blows hard but does not get cold. Tried recharging the A/C with no luck so far, and the car does idle a bit odd when the AC runs. Compressor issue maybe ? @@BPROAUTO95
