Audi A4 B9 - only hot air blowing on passenger side

Hey guys,

 

I have Audi A4 B9 2017. I have dual climate control on my car and when I say have temperature set to LO, the drivers side gets nice and cold but the passenger side is blowing hot air, regardless if I change the temperature or not.

This has happened twice in the past few months now. After turning the car off and leaving it for a while then turning it back on, it seems to work fine again and I get cold air on the passenger side as well but I have a feeling it may get worse. Any ideas what this could be and if it's a easy fix? 

 

Cheers

It's likely the air flap motor is faulty on passenger side.

Thanks, heh so I actually replaced my regulator motor for recirculation flap 4m0820511a this summer as it wasn't blowing any air. Costly those actuator motors 😅. 

Any idea where this air flap motor is located in the car? I'm presuming it'll need programming by someone who has VCDS too? Also would it be the same part number as the recirculation motor too?

 

The only picture I have under the glovebox from when I replaced the recirculation motor(example 1) was this one but I believe (example 2) is the fresh air motor. I couldn't see any others for the passenger side.

    Thank you Sid, I appreciate you. I don't suppose you have the PDF/document you could send me for instructions too where it references the pages?

    I'll have to get error codes read to see where the problem lies with which component but may be difficult as it's intermittent but rather do the research now.

    Unfortunately I don’t but I have access to abit more info which might be of use
