I was on vacation in France. Very hot .. and on the day of the way back I saw this pool of water next to the car.
This is the left front.

Turns out the air conditioning no longer functioned.

Do I have to go past the garage? And how long are they working on this when a leak is found?

Not sure that's an ac leak that would only be the excess water that you sometimes get its a bit like condensation

Ah, that would be better
But it feels like whether the air conditioning works less well than before.

Get a small thermometer and see what it actually says temperature wise when its set to the lowest i think they should get to about 5 degrees but maybe some gas as got out when was it last serviced the air-con

If it is very hot/ humid there is always a small pool of water under the car once you park up - the main thing is do you still get plenty of cold air from the vents, if so then it is normal if not then you need to get the car to an aircon service - car will be drivable BUT in hot weather not so pleasant with no cooling air inside. 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it
