Hi everyone, I own Audi Q8 2018 and have an issue with air coming in the front of the vehicle when AC is on. As soon as i stopped the A/C the air starts coming from the front too. The A/C is working fine but the air is blowing only from the rear. Has anyone experienced this ? Thanks

I have an Audi A4 Avant 1.4 TFSI 2017. Is it possible to replace the Air Conditioning Control Unit with another from a standard A4? The units look identical, is it as simple as plug and play? Thanks.

Good morning, I have had an issue with my A3's air conditioning for about a year now.. i've just never needed to really get it sorted because.. well it's England, how often do you use Aircon haha. The Audi A3 I have is the SE TDI 1.6l 2013 model. Basically, it was working fine - air blowers normal and then the air flow turned ice cold when I turned A/C on. On a road trip to Newcastle last April I turned the A/C on and.. nothing. The blowers were fine but everytime I pressed the A/C button, the red LED came on as I pressed down on the button but the second I took my finger off the red LED went off. So, I thought I would take it to Halfords for a quick regas.. they regassed it and kept the thermometer in the vents to check the temp. It filled it and in doing so it meant that the red LED stayed lit after I had taken my finger off which lead me to think that it had simply ran out of "gas" in the A/C. But, it still wasn't going cold. Fast forward a year and I am still in the same predicament - Red light comes on and stays on but the blowers don't change air temperature at all.. not fun in this recent hot spell that we have had. And with two roadtrips coming up (one from Manchester to Newquay in August) I am looking ahead to trying to get this sorted in advance. Had a quick check around the car last night - now I must admit I am a complete novice when it comes to anything mechanical like this but I am pretty good at learning stuff and being able to fix simple things myself - I know where the fuses are and all that sort of stuff so I am not completely useless but definitely no expert. I identified what I am pretty certain is the compressor in the engine, driven by a belt at the front left of the engine. This belt is constantly running when the engine is on - not sure if that should be the case (i'd presume it should only be on when the A/C button is on?) but there is definitely a high pitched whirring sound added to the engine noise when the A/C button is pressed and i am 99% certain it is coming from what I think is the compressor so... in my eyes I am pretty sure the compressor is working as it should. My original diagnosis is that there could be a leak where the "gas" (sorry I don't know the name for it atm) in the A/C is just completely leaking out when filled. This is backed up by the fact that I think the compressor works as it should when it is pressed and having it refilled enabled the red LED light to stay toggled on when pressed as opposed to going straight out when you take your finger off the button. Audi want £60 just to look at the car and that's before they quote me a ridiculous price to change something that's probably quite rudimental. Any ideas? I looked at the fuses last night but I couldn't get the aircon one out (need some needle nose pliers) but with it sounding like the compressor is activating when the button is pressed I can't see it being an issue with the fuse or else nothing would happen, would it? Any help would be greatly appreciated! Lee

My 11 plate A1 was off the road for a week in November, as an air conditioning pipe failed. The entire dash was stripped put during the process. Now my air conditioning has failed again and the car faces another period off the road. Am I the only one to experience this problem? Cheers, Stuart

Hi there, I've just bought a new Audi A3 and love it very much. It's way way better then my old punto and polo. It's great to see there is such an amazing Audi community on this site that I can proudly be part of. I've got a question which I was wondering you guys could help me with. My AC only turns on when it's on full power (Level 4). However it does work properly on level 4 and the air is nice and cold. It doesn't blow out any air on levels 1,2 and 3 on normal roads. On the motorway, the other levels suddenly and magically decide to blow out cold air appropriately. Where could the issue be? Many thanks in advance
