i had my loads of trouble with the climate in mine not being very cold.
it kept tripping out, had to have it reset loads.
had a bloke out to look at it for me to get a second opinion, he re-gassed at 2 years but when he tested it, it turned out the pump wasnt working again.
took it back to the dealers and they replaced the pump.
the climate control has never been so cold now. cant have it on 15 for long now before its too cold, even on the hottest days weve had.
i was advised by the dealers to only use the AC on fan setting 3 and not on auto.
as when you put it on auto, the fans spin at full speed and sometimes the censors think that the pumps going to over heat and so shut it down.
