96 A4 fog light question
 

As i have just got my car and started to look for things to change i have noticed that there are no fog lights on my car, correction the fog lights seem to be located in the headlights.

If i am planning to upgrade to the depo headlight face lift with black projectors, will the car throw codes as it dose not seem to have a place for the foglights?

Would i be able to retro fit some from a 98+ into the lower grill and re route the wires to be able to avoid these codes?

Thank you,
