Error code: B1423 on a brand new car?

Just used Carista to switch to a single beep when reversing. Whilst I was in the app, just out of curiosity, I checked for error codes. I didn't expect to see anything as the car is brand new.

However, a code did come up. Has anyone seen this before? Should I be taking the car back to the dealer to investigate further?

 

I did reset the codes, and read them again, and it still came up. It's not the window, the code is for the AC, unless we have different meanings for error codes by country?

I suspect the AC is broken somewhere, as it was 26C (79F) today here, quite humid, and despite putting the AC at LO (which is even below the 15C (59F) in the photo), it didn't cool me down. I put my hand in front of the vents and it just felt room temperature.

I spent the whole day with the windows open, as the air outside seemed to be cooler than the air coming through the front vents.

In your Gen 4, when you put you AC on, is it 'ice cold' at the lower temperatures?

 

Thanks both for the feedback. I shall contact my dealer.

 

Turns out there was a leak in the AC system. The dealer fixed it. Nice and cold now. I'm so glad it's a brand new car under warranty, as if I was paying for the repair myself, they said their hourly rate is 144 pounds, which is north of 200 US Dollars. Ouch.
