Fog lights question

[Bullit]

Hi everyone I'm new here and to Audi's and need some help. Neither the front or rear fogs work, all the fuses are ok and iv managed to find some wiring diagrams on the net but don't know where the relays are to check them.

any info greatly appreciated

You don't say what car you have...

A4 A3? Etc.

Most relays are under the dash on the right side on an A4 B5 and a couple under the bonnet in the ECU tray...

Well, he's posted in the A4 B5 section, so I'd presume that's what he's got, although knowing the model spec and year is often helpful.

Have you actually checked the bulbs?
Sorry if this is teaching you to suck eggs, but I've seen a lot of posts where people have assumed that because both headlights aren't working, it must be the switch or relay, then it's ended up that they've just blown bulbs at similar times.
