Can anyone shed any light?\n\nI think the DCC on my '02 GTi is acting up.\n\nAt the moment, with an ambient outside temperature of around 8'C and the\nengine fully warm, anything below about 23'C set on the panel shuts the\nfootwell air off and it starts blowing cold (outside temp) air in. The\naircon isn't cutting in, but it gets bloody cold in the car. It never\nseems to blow hot air in at all (warm is the best I get). As soon as I\nswitch from auto to eco, all that seems to happen is that the windscreen\nmists up (something which I normally associate with having the recirc\nswitched in). I thought ECO was designed to save fuel in hot weather and\nattempt to cool the cabin down using outside air rather than aircon\ncooled air. Also, tonight, with the target temperature set at 23, there\nwas a cold draft - it was shoving cool / cold air up through the screen\nvents.\n\nMy main dealer says "well it's getting warm / cold as you change the\ntemperature so it must be working OK". Needless to say, I'm not\nconvinced. At the moment, I'm dreading it turning really cold in case I\nhave to start driving in gloves and a coat - something I loathe.\n\nThe thing is, I certain it wasn't behaving like this last year...\n\nIf anyone has had similar experiences, I'd like to hear from them.
