Thank you :-) And do you know if the dealer can really know that the problem is a leak on evaporator coil without removing the whole dashboard ?

Any idea ?

Ok, so I used a gas leak detector and it seems that the leak is really around the evaporator coil.

Is there really nothing else to try but remove the dash completely to change the coil ?

I might prefer to refill few times a year until I decide to change it if the only solution is to remove the dashboard.

By the way, do you know if when evaporator coil has a leak, compressor oil could also leak from the evaporator ? As it seems that oil is mixed with gas in the system ?

Or maybe most oil will remain in the compressor and can hardly leak from the system ?

If oil can leak from the evaporator coil, should I find oil under the car when parked ?

thanks again !
