Someone mentioned to me my brake lights were out, so I went home and
tested it, it was not the brake lights, but the rear-fog on the passenger side
was out (the one that turns out when you turn on fogs).


I checked the bulb - ok
I used DMM and no voltage (on the passenger side), the other side is fine.

Any and all help/suggestions is greatly appreciated.

Thanks,

 

Fuse?

 

no Porsches have right rear fog lights...euro spec to indicate to other cars the side to pass on (driver's side)

 

Maybe mis-spoke on the name, I used the terminology I found on the wiring diagram.

So is there rear (red lights) that go on when you turn on your fogs? if so one of them is not working...

Sorry about the confusion.

 

Left and right are connected to same fuse and switch, so if one works and the other one can rule out fuse, switch etc...

 

Chuck,
For our reference I am posting the image of the wiring I was talking about.

 

if you open up the right rear light housing you will find the socket for the fog light and no bulb...you can put a bulb in and it won't work...would you like to know how many people have purchased bulbs thinking that Porsche missed it during assembly only to find that it doesn't work anyway? Only the drivers side rear fog light is functional

 

God damn it. Chuck I really appreciate the info. Man this was driving me nuts.
Is this documented somewhere?

I guess I must be stupid.

stupid is opening the housing and seeing the empty socket and going to the stealer and paying $20 for a bulb that won't work when you put it in

 

Chuck is right...it is US DOT regulation...only one bulb on rear fog can work on any car sold in the US legally.

 

The Germans and if fact most Europeans have some, at first glance, interesting idiot racy with their lamps.
There is only a rear fog lamp on the driver’s side - Means pass to the left (right side passing illegal).
When you turn on the fog lamps, the High Beams go off and vice versa.
You can turn on right or left side only parking lamps, weather via lamp switch or turn signal indicator to the side you want to be on - with ignition in OFF position. So nobody crashes into the car while parked on the side of the road without street lights.

 

There are no stupid questions. Just stupid results from not asking There is so much knowledge on this forum and I'm not affraid to ask anything. And I always get an answer. Great group!

 

On many new Audis in the US both of the rear fogs light up- but in Europe, only the drivers side should illuminate- so in the UK it would be the other side- hence the socket for the bulb, but no bulb.

 

I admit I did this too. Thought my right rear fog light was out when I bought the car. Fortunately, I searched this forum first and found out that's how its "supposed to be" before I bought a fog light . I guess the reason for it in the US is safety requirement, something about making it look like your brake lights are on always or something silly like that.

 

Not only trying the bulb but special ordering a $180 replacement wiring harness as well and then reading this ... DUUUHHH.
