Heated windscreen
Now that mornings are little more chillier I expected to see the magic of heated windscreen, very disappointed to find out it doesn't work.
Not sure where to start at diagnosing the problem, can't find the fuse either. If I'm correct it should automatically turn on when it's 2C or below and defrost button is pressed? Any help would be appreciated +++ |
Temperature has to be below 5 degrees and the HVAC needs to be on 'Auto'. If you have access to VCDS then you can scan it for errors and also use it to perform the Output Tests on the HVAC system. If the conditions are right then the amber light should flash on the button when in use.
As for fuses, I don't believe there are any (or at least none that I can find) as the control unit fitted in the boot is wired directly to the battery. The battery also needs to be in relatively good condition as it draws a lot of power. |
When it is operating the tell tale amber light in the button will blink

It is 0.5C at the moment, and nothing happens. HVAC is clear of errors :Confused: |
Did all D2s have a heated windscreen? I had no idea that was even a thing.

It was a pretty rare option.
Back then the patents/licences for it were almost all held by Ford which is why they had it relatively widely available, even on my 1998 Focus (one of the first out of the factory). I presume Audi decided to pay the fees to Ford for their premium model range. And I'd guess Ford would be happy to take the money as they had no competing model. |

hunker7 - Do you have this in the area above the battery? If not, then you don't have a heated windscreen. |

Light starts flashing after about a second and it took about 1.5 minutes to completely clear the windscreen, which isn't bad considering it's been frozen since last night. I wonder if there's a fuse inside the controller module considering there's no other indication of one anywhere, and you'd think it would need one with its power requirements. Possibly behind that small panel at the bottom where the large cables go in. |
