How can I fix the fog light issue on my Audi A4?

The fog lights on my Audi A4 are not turning on even after being replaced twice. I'm not sure what the issue could be and need some guidance on how to fix it.

First, make sure the fog light bulbs are the correct type and wattage for your Audi A4 model. Then, check the fuse box to see if any fuses related to the fog lights have blown. If all else fails, it may be a wiring or electrical issue, and you should take it to a certified mechanic for further diagnosis.

It could be an issue with the fog light switch or a faulty relay. I suggest checking those components and replacing them if necessary. You can also consult an Audi dealership for a diagnostic test to pinpoint the exact problem.
