Re-inventing the wheel, DRL for an A6
 

I had to install DRLs on a 1999 A6 I recently imported. Having read through a bunch of threads, I spent some time with the wiring diagrams.

It looks like the factory had a pretty simple solution. They taped line 3 of the light switch, through a module described as a circuit breaker and then to the output line of the fog relay. I'm assuming the module acted both as a fuse and reduced the fog lights to 80% power.

Taping at line 3 of the light switch powers the fogs only when the headlights are off. With the headlights on, everything operates normally, including the fogs.

The pin for connecting line 3 is available as a pigtail from the dealer for about $6. I taped the line from the output of the fog light relay and spliced in a 10 amp fuse. The only difference from the factory version is the fogs now operate at full power instead of 80%.

Thank you for the info... I'm sure the guys bringing in the A6's will find this info very helpful!

I am most interested in doing this with my US spec allroad. Any photos or more information would be most appreciated. Thanks

I like to do the reverse (disable my DRL) because I installed HIDs. Right now I just make sure I turn on the lights before I start it.:P
Anyone knows how?
