View Full Version : Fogs not working

Recently my front and rear fogs have stopped functioning. I have done the mod to the main fog control box to allow lights to operate independantly, and have re-checked it to make sure the solder and wire are still intact...they are. I have also checked the fuses, those are fine...and I am not getting any codes with the VAG. Anyone have any idea what could be causing the interuption? Could both front and rear fog relays be bad (#4 and #5) ? Or could I have fried the main control box by doing this mod? Before I order a new one I thought I'd check here.

check the bulbs. My fogs went out right about the same time. It's possible.

wouldn't that show up on the MFI display? I doubt that both fronts and the rear all blew at the same time. The lights on the dash buttons do not light up when pushed in, so there is not power getting to the switches either.

someone posted about this a couple weeks ago.

I had a problem when one of my fogs went out. I replaced the bulb, and checked the fuses, but that didn't work, so I used a current tester to find out what was getting current, and what wasn't. It turned out that the fog was not getting grounded, so I just re attatched the ground wire, and it worked.

Last time my fog light went out the warning display on the dash didn't come on.
