Hello Ber31inger, Promised to come back with some updates as I found out something After several tests and reading values using VCDS and OB11 all the values appeared to be OK except the ones below: 1. Pressure in BAR (while running at idle) was low: 10 BAR ; 10.8 BAR (maximum recorded) - outside temperature when doing the test + 25°C 2. Left, Right and Foot temp sensors where not showing the same values (Left sensor had the lowest values- most probably because the Air Conditioning is going into the car from Left to Right- why I am saying this is because I switched the left and right sensors between them and same values => the sensors are OK) 3. Evaporator sensor was showing almost the same Celsius degrees as for the Left, Right and foot temp sensors - normally the evaporator sensor should record lower temperature like for this example: Temperature set on AUTO to 22°C, left,right and foot temp sensors should read 13-15°C while the evaporator 7°C (or even lower; close to 0). Because of point #1 and #3, I realized that maybe I don't have sufficient refrigerant gas in the system and I went for a check. The outcome after this check was that I only had 150gr OUT OF 500gr - this might be the reason of low pressure and high evaporator value. After completely filling the air conditioning system the pressure when to 11.5 - 12.5 BAR and the evaporator value dropped to 3-5°C and the air conditioning is making much more cold and much faster than before. (I didn't had a long trip since refilling so I don't know if my old problems still persist or not) PS: In the past I also had the symptom of auto-closing the flaps (no air coming through the vents) but that was solved by changing the cabin filter Hope this helps your investigation too Cheers, Florin

Thanks for you quick response mate . I am currently investigating the problem and promise to come back if succeed (fingers crossed). But if you'll find first please let me know Thanks Florin

Hello Ber31linger, I have a 100% similar problem on my Octavia 3 and I am wondering if you managed to solve the "mystery"? Thanks a lot!
