2004 audi a4 sedan 1.8t when i turn on the rear high beams and the drivers side works but the passenger side dose not work the bulb is fine and there is ground there is no positive power to it and the same on the connector there is no power..any suggestions would be great..

 

To the best of my knowledge that is just the way it is.
I have the same issue.
I have talked to a few mechanics, and they've all said that the b6s they've worked on all have the same thing. One single "rear fog light" light. Useless and I'm unsure why it is there.

 

One rear fog light on side of driver is normal. Some say it is a "safety" design.

 

there is only one and it is a safety design. next time it is raining/snowing/foggy so badly that you cant see the cars in front of you very well just turn it on.

 

It's a European spec that they left on the US cars. In heavy rain, snow, or fog it makes your vehicle more visible to reduce the chance of getting rear ended. If you want two lights, you need to buy a 2003 A6. :-)

 

thanks for the reply they should still have both on.....

 

as far as i know euro-spec cars do have 2 rear fogs. US cars only have the driver side. ive seen people put the passenger rear fog in, so im sure theres some DIYs if you want another

 

I recently purchased the Bentley repair manual on cdrom. After extensive research trying to find a wiring diagram for the right rear fog light on my 02 Audi A4. The diagram reveals that that light is not wired into the J519 Vehicle electrical system control module fig No. 2/14. The same figure shows connection L46 for Left rear fog light only. No mention of right rear fog light at all.
