I'm asking as my car was in to get washers fixed - took 3 trips!
The last time the Tech came out to demonstrate it was fixed so he started the car, switched on the lights and operated the washers.
Only the N/S headlamp washer operated and I was about to say, "see, told you!" when the O/S one fired up!
I asked the guy about it and the reason is so you don't lose all the light - Audi think of everything!
Then I mentioned the heated mirrors seem to have some weird logic so he told me that bit too!
There must be an Audi Training Guide somewhere......
I'd like to reduce the number of headlamp squirts to say every 5 or more window squirts like my son's Merc does. Loads of stuff like that I NEED to know.
