Having had an assortment of Audi A3's including 2 S3's I was driving this morning and scrolled thro the DIS functions and came across one that I've never seen before and certainly wasnt showing before. Air conditioner economy showing in 1/4 gallon units on a sliding scale. This has just popped up since the other day as it certainly wasnt showing then. Any ideas why it should just appear with out being selected. Bizarre.!!!!
