Sorry for the Newbie thread. This topic has probably been covered already but after reading through 30+ threads I still have questions.
So here goes......
I have a 2008 S3
I have heard members say that their heated wing mirrors dont activate until 12 degrees and some at 5 degrees.........so I waited until today due to the unseasonably warm weather to see if they work. I have tried at other times but it never seemed to do anything.
Anyway today the DIS came up with the frost symbol and it 5 degrees outside. I pushed the switch forward and that was it no light or anything. My mirror wasn't frosted or misted up and I dont know whether its working or not. If it worked then I couldn't tell. I dont want to leave it until I really need it. If somethings wrong then I'd want it fixed before the big freeze.
Is the heated mirror logo supposed to light up when its working and/or switched on?
Is 5 degrees too warm?
Is it just a manual thermal switch that controls whether it turns on or not?
Also how are the heated jet washers activated. I like the idea of them but I dont want to rely on them and find out that the wont defrost a windscreen. Are they any good?
