Hi everyone,
i bought few month ago audi Q7 4L fully loaded with equipment.
As far everything works but i started to have some issue.
My Q7 have 4 zone climate control.
First and most important is that my A/c blows cold air in front, but on the rear it blows warm air.
I can post scan but car does not have any codes regarding front or back A/C only one stupid code for air quality sensor but that souldnt be causing this problem.
i need to tell you that yes my A/C is full whit gas, i double checked all motors and actuators on rear HVAC unit, and blower is spining allso, car doesn not have any A/C leak. Also i tried and replace front and rear climatronic and removed CP and still no fix.
i urgently need soultion for this problem because i live in Europe and warm weather is coming and i am driving my wife and my baby behind.
- second problem is that car is trowing 2 stupid codes in Address 42 (drive door) and address 52 (passenger fron door) that both my rear left and right door contorl module does not have any signal or coumincation.
I replaced both rear modules with few spare one fron parts yard, and replaced front passenger module also with few others and still same error codes.
I realy dont mind this codes on door modules because all works fine except child lock, whenever i start car and moving, child lock kicks in and as my wife is driving in rear seats with baby everytime i stop car and we go out i need to open her door, it is not problem but it is anoying. I tried screw on inner door with lock picture and i rotate it but it doesnt do anything.
thanks for your help.
