I have a B8 A4 but we have the same HVAC so I thought I’d ask here as the traffic is a bit more brisk than the A4 section.
It was about 70 degrees on Saturday so I turned on the AC, but it just blew warm air.
Wondering if anyone has had this happen or has had similar codes…hoping it’s just a replacement of the sensor. Havent seen a DIY on that anywhere, so if you’ve seen one, please link it up.
