Hi. You don't mention where you are from. Is it a LHD or RHD model?
I had the exact same message on a UK, RHD 2002 Audi A4. As you may know in the UK we only usually have a fog light on the rear right (drivers side) and the left bulb socket is empty. You can add a bulb on the left but most UK drivers do not and leave it empty.
I've never had a bulb in the right hand side and the right rear fog lamp has always worked well.
The other day the driver display suddenly popped up the message that the rear left fog lamp had blown! Very odd indeed since it hasn't got a bulb and has been happy like that.
I'm guessing it was some strange 'false positive' caused by a bug or short as when I next started the car the error went.
If anyone knows what would cause this I'd be interested to know. Do mainland European and North American Audi drivers with only a left rear fog bulb and no right bulb get false 'right rear lamp' errors too?
(or are they all fitted with bulbs on both sides as standard in those regions?).

The problem is I am getting an error message on the display saying that my rear left fog light isn't working, although I am lead to believe from various sites that there isnt a rear left fog light. What could the problem be?
Model: A4 2004
