I have a 2000 A4 B5 (facelift) with foglights in the front bumper. When i press my front fog button on the dash, just the fronts come on as expected. When i press the rear fog button, both front and rear work. I can understand the idea of this function but im capable of operating them seperately if needed.

What id like to know is if i can disable the front fogs when the rears are on? Is it a simple case of a wire connecting the rear to the front when the rear fog button is pressed, or is it a relay that needs changing or removing?

The result i want is :

Front Fog Button --- Front Fogs Only
Rear Fog Button --- Rear Fog Only

Thank you in advance
