Thanks, I will look into that tomorrow. One more maybe important point, when set to “Sync” and “Auto” there is no blowing at the back and middle central front console at all. When I switch to manual and crank up the temperature it do blows hot from all the vents in the front, rear starts blowing but at outside temperature(or close to outside temp).

Hi Ian, Thank for your suggestions. Yes I have Carista and I did a HVAC calibration, nothing changed. On Thursday I will visit coding specialist who is certain that he can fix the issue. I will keep you updated.

Thanks, what is not clear to me(please see the photo) is this a UK glovebox removal. If so than on lefthand drive side I would need to approach it from the steering wheel side, right? Another thing that don’t make sense is if the heater core is blocked then there won’t be any(or poor) heating in the front either. My heating at the front is great, on the back console and back footwell only cold air is coming out when in heating mode. Could it be that some flap/servo motor that redirects cold/hot is stuck in cooling mode? Btw, air conditioning works great, no problem there. All the best!

Hi Guys, I am having the same heating issue on my 2018 A4 Allroad. Can you help me with the exact location of the heater core at my car? There are some conflicting info on the web, some saying that complete dash must be removed. My car is lefthand drive. Many thanks, Ivan
