I recently was checking out a taillight/fog light bulb out error I captured from vagcom. I replaced almost all the bulbs and see that my fog taillights still don't turn on. I can't figure out exactly which bulbs are the fog taillights. Could someone point me in the direction?
I noticed some bulbs were super dim and the glass looked brownish like it was blown but was still turning on.
I basically want to know which bulbs are which so I can trace back the signal.

I know its one of the inner/trunk lights. What I would do is put the car in neutral with the parking break on and have someone click the brakes on and off to see which are the brake lights. Then turn on the fog lights (pull out the light knob twice) and see if one is working or not. Removal of the tail lights to change the bulb is easy. I believe they use 1156 bulbs.

Nope, only the outside lights light up for braking. The B6 has a rear for on the trunk but only one side lights up, purposefully. I'm really glad we got the symmetry for both sides or that would bug me.
Only driver side rear fog here, was also like that on my b6

Two rear fogs on my B7:

And yes, they are the inner two lights on the trunk lid.

You just need to replace a bulb. Both sides should operate on the b7

Was possitive it was that way since it was this way on the B6, I have a spare bulb somewhere...

Yeah, I'm an 05.5 even, and I have both rear fogs.
