The headlamp washers come on every 5th pull if I remember correctly, OR, you can pull the stalk back for a few more seconds than normal and the headlamp washer will come on also.:I have a 1.8 A5 with the interior light pack. I note the footwell lights on a friends Q7 stay on all the time, however on my A5 they appear to dim out once you have openend up the car and settled in. Is that the case with all A5's?
Secondly, my headlamp auto wash seems temperamntal in that i could pull the stalk 5/6 times and it wont work and sometimes it will come on with just one pull. Do you know how oftne this shoudl work and whether or not you need to preset anything before it works as normal?
