Guys, the dash light comes on intermittently on my 2007 a4 cab saying the rear high brake bulb has blown- it hasn't. It's very annoying and I'm guessing its a faulty connection. Seems to happen more when it's raining or after it's rained. I took it in for a service today and mentioned it to audi. It's now back with the dash light on all the time and the rear light isnt working at all when it had always worked previously!
Any ideas or suggestions? They want £290 to replace the whole unit but I'm sure they've fu**ed it! At least the light was working before it went in I just had to live with an annoying beep every now and again...now Im forced to address the issue!!
