Sorry for the basic question but I can't tell if I have heated wing mirrors or not I've read what I can find on the site and still can't decide. The other morning the first frost (minus 2) since I've owned the car and the mirrors don't clear so that got me thinking, do I have them and they don't work or are they not fitted..... The user manual doesn't make it clear either on one page it says the mirrors activate when the temperature allows and on another is shows a heated mirror symbol (not shown in the relevant diagram), so do you need both for the system to work? The switch I have shows a left and right mirror with a vertical line in the middle, no sign of the heated mirror symbol. Any ideas? Car is 08 2.0Tdi S-Line cabriolet.
