It was really cold today and the car was iced up (the temp displayed -1.5) so I ran it for about 10 mins to warm up before turning it off to go inside.
When I came out 5 min later and turned on the ignition the air/con heater display showed every numeral on the lcd screen! It then began to flash with a full lcd display then blank etc. :confused:

I turned the ignition off and back on again a few times and the same thing happened. Getting slightly worried I started the car and the display turned back to normal except the temperature display now read 9.0c ?:blink:

I drove the car a few miles and the temp slowly fell to around 2.5 c which is about right.

The display now seems fine when turning on and the temp has returned to normal its wierd.

Has anyone had this full lcd display flashing before? :confused:

I am hoping it does not happen again :( I didnt know if it was some kind of code with the series of flashes. Its due a service in march which may flag something up, its weird the car drove fine :shrug:

The flashing tells you that the system has detected low refrigeration gas pressure. I think that the cold makes the gas contract a little so in normal weather/temps you will prob be fine. Look into getting the system regassed if it does it once the weather worms up.

Thanks Nath :D

It was a bloody cold morning and the car had sat through a couple of days of freezing weather which could contract anything. As long as it nothing serious :funk:

Exactly same thing is happening to me, up in Scotland. Seems to be happening on the really cold days and usually when I've had the car sitting parked for a day without use.

Doesn't do it in normal weather conditions. Go away snow, :(.
