While checking to see if all my lights were working, I noticed that the REAR Fog lights are not coming on (FRONT one's are coming on). Still need to check to see if bulbs are OK.  After checking the Bentley Bible I see that there can be three (3) things coming into play; 1) Light Switch, 2) Fog Light Relay, and 3) possible faulty wiring. Does anyone have any experience in trouble shooting this issue? or insights into the problem?  I do have a Durametric Diagnostic System but there is no info in the system that pertains to the Fog lights.

There is only one rear fog light on US/Canada cars.

You did read the operator's manual section about the light switch? (just checking)

I would suspect the headlight switch first (other than bulb).

Loren....thanks so much in pointing this out, completely overlooked the "second click" note. Tried it and the left one comes on and the right one doesn't,  will now check the bulb! Thanks again for the prompt response! Just got the car recently and still learning all the bells and whistle's .......

Any and all German cars factory fitted with a rear fog light will indeed only have one.  On the driver's side.  So, right side for UK models, left about everywhere else.

 

To have two would create a situation indistinguishable from brake lights.

One red tail light is called a "fog light".

 

Two red tail lights is called "brake lights".
