I have the warning indicator on that reports a light bulb is burned out, but all my lights are on and appear to be working. What is the best approach to this problem?

Generally that happens when your low beam bulbs burn out. I have had that happen a couple of times, no warning, no indication leading up to it.

I would just replace the bulbs.

The light will go out if you have ALL bulbs working correctly and have the CORRECT bulbs installed. Check again.

Yes - the fast flashing is a warning that a bulb is burned out. Change the bulb (be careful to put it in the same as the old one as it probably is 2 bulbs in one , parking and turn/stop) and you should be fine.

The switch is fine if the third brake light is functioning. Even though the tail lights work, the filament for the brake light can be burned out. Sometimes they look intact but are still burned out. Replece the bulbs.

this indicates that you have a taillamp out. you must replace the burned out bulb with the correct bulb or the light will work but the warning light will not go out.

probably one of the tabs on a light bulb heated up and melted, causes contact to be lost.just remove lights and check each bulb for oblivious melting and bend contact out,away from plastic on the bulb to get a better contact on the inside of the socket. happened too me in the rear tailights.

This is the taillamp failure indicator. You either have a burned out taillamp or a burned out brake lamp bulb(s). Please make sure when you check for inoperative brake lamps that you make sure that the brake lamp in the rear window works, also.

There are two black plastic clips behind the the air filter, remove them and release the whole assembly to access the lights.

If you still get in troubles, have it replaced at a petrol station, they will help you in fitting the bulb, and it won't be expensive.

I had the same problem with my 06 TDI, it ended up being a weak filament in the small marker bulb located in the high beam housing . The light was on and off for months before I NOTICED ON 1 OCCASION THAT THE MARKER LIGHT WAS OUT.

GOOD LUCK

You probably have a frayed wire leading from the main cable to the headlamp.  Look closely where it may be touching the frame and see if you have any wear etc.
