I have had the aircon re-gassed and tested for leaks - all good, 6 deg C output at 31 deg C ambient...
However, after a few minutes the cooling effect lessens and a couple of minutes later its pumping ambient.
Someone said its "the sensor behind the airvent - its is the most commonly failing one" but I / he didn't know which airvent and how to test / whether this was possible.
Does this sound possible ? or any other suggestions / tests to do would be very welcome...
The Volvo dealer wants a week to book in and sound like they will keep replacing bits 'till the system works...
Thanks,
Nick
