Passing you soon
All my dashboard and External lights flash off/on when I puit my window up!
I own a 2003 4.2 A8. Car just out of warranty and I noticed this problem when driving off a car park.
It only switches off for less then a sceond but I'm now concious that I mighjt flash inadvertantly at an oncoming car at a junction. Unless they own another tanker like mine they're going to feel a whole lot worse than me in my cocooned safety.
Can anyone help? or is it a visit to the auto spark?
