Hi, can't see that you've said, but apologies if you have - which Alfa model do you have? I have a 156 with a multi function display in the top middle of the dash that tells me about low fuel, low outside temp, when doors are open etc. All other warning lights (air bag, alternator, ECU fault, air bag fault etc) are between the rev counter and speedo. Which one is it? The display on the first one I mention is generally rubbish unless it is cold, as soon as the cabin starts to warm up and warm air passes through the vents surrounding teh display unit it fades away. If it's the unit between the rev and speedo - there are plenty available on Ebay.
