Folks...the ACC has started behaving oddly. It works for around the first 30 minutes of a journey, though tends to heat the cabin a bit more than the temperature setting suggests it should. After that time the air coming out of the ducts rapidly cools, until even with the control set to 21C it's just plain outside temperature air. If I crank the setting up to (say) 25C it will warm up for a while, then it's back to cold again. So does it just need a gas top-up or is it something expensive? The compressor is obviously kicking in, so what's left?
What does the jury think?
