[align=left]When engine is warm and outside too and shut off the car, re-starting the engine within a few minutes, the a/c blows very unpleasant hot air for over 30 seconds and then a little cold air starts poping out. The passenger vent is the worst as it takes more than 1 minute with warm air to start cooling. All this with recycle mode.

Second point: how to eliminate the open door chime?

Your suggestions to overcome them, please.

Hi therely , i have exactly the same problem and even worst the passenger side is constantly blowing warm air. Did you manage to solve the problem
Many thanks

 

I still have the problem. The last dealer changed the evaporator and put more freon. Now vent #2 from left side is not so cold and when you re-start the car a lot of hot-humid air comes out of all the vents and is very unpleasant.

Will take it to the dealer again and will report later. Good luck with yours.

 

guys i can help you narrow down this issue. im no car guru but i know from experience. ur either leaking freon due to a hole somewhere n your ac hoses or ac compressor. have your local shop run a check on it cost $$ (moderate). basically what they will do is run freon with dye n then check to c where the dye is leaking from pblm solved.

 

if checking and discovering there is no leak in the ac compressor or hoses. have them recharge your system freons prob low.

you can check to see if your heater core maybe bad although unlikey still a possibility. way to check for this is feel if the passenger front floor is wet if so thats antifreeze and cost to fix $$$

 

They changed the compressor, charged the system, checked the hoses, and it stills blows very warm air for quite a while after restaring the engine. Is unpleasant and does not cool enough for hot weather.

 

Do you own a vag com? Can you pull the fault codes from the A/C control head for us? The vag com is also the tool you use to turn off the door chime as well as seat belt chimes etc. www.ross-tech.com

 

I do not have one but according to the dealer, they solved all the a/c problems, so I assume there are no more fault codes.

 

I've been to the dealer today and i was told the problem is the duo water heater valves which is located next to the cabin air filter . There is no fault code on this part that is why the vag computer software wouldn't register it. The problem now is that this part can't be repaired and a new one cost over 500 euros . Did anyone ever tried to repair the valves

 

Have you resolved the a/c hot air problem. I have not.
