Hello, I have a 1999 Audi S3 Quattro and every now and again the brake bulb warning indicator comes on on the dashboard. I have checked the connections and changed the bulbs and it still does it, usually when I floor it, corner sharply or go over bumps but it does do it every now and again when it is stood still. Has anybody else had a similar problem and any suggestions? Please help, its very annoying. Cheers.
