I have a 2008 A4 2.0T with less than 11,000 miles. The front left turn signal has stopped working (most of the time), like it's burned out. It started working again a couple of times, but stopped again as soon as it was parked for the day. The last time, the light blinked when I went out to the car and unlocked the doors with the remote, but the error came up and the light stopped working as soon as I started up. ANY IDEAS? Anyone know where I can get a maintenance manual or instructions on how to remove the bulb? Thanks.
