Air conditioning problem

[Turgay e-tron 55]

I had an issue with the air conditioning in my 2019 e-tron 55, so I took it to Audi Milton Keynes. The problem was that I couldn’t activate the AC either through the mobile app or directly from the car. It was showing a fault code, but the code only indicated that the AC wasn’t working—without explaining the cause.

 

After checking several forums, I found that it could be a pressure sensor issue. I shared this with the service team, but they insisted it was a wiring problem and said they needed to perform wiring diagnostics.

 

In the end, it turned out there was no wiring issue at all—the problem was caused by a £100 pressure sensor. However, I still had to pay an extra £400 for the unnecessary wiring work.

That sounds about normal for a couple of hours work.

Audi service desks don’t listen to hearsay or talk of forums however well intended. Minimum is they will scan car with VCDS, then perform repair. Their labour charges are horrific.

Just purchased my 2021 E-Tron 50 and my AC has the same behaviour.  It comes on initially and then stops working after a minute or so.  I have a 60 day Arnold Clark warranty and i actually purchased an Audi extended warranty that starts in June too.  Seems to be a pretty common fault unfortunately and bad timing with the current weather :-(
