I'm going to replace the fog halogen bulbs with LED lights.
First time removing the fog light cover on the car and it looks a bit different than my A4
I noticed a Philips screw on the top left and was wondering if this screw was holding in place the cover and had to me removed?

I also noticed a little hole on the bottom right which looks like is used to pull the cover

Are there any tabs around the edge I need to pray down?
Also last question, since the S5 has is equipped with LED light from the factory, how does canbus works on these cars?
On my A4 swapping halogen bulbs for LEDs would throw a bulb out an error message in the dashboard because the car is expecting 35W to be drawn by the bulb. TO fix this I had to install a load resistor to trick the computer into thinking that the bulb was drawing 35w
Will I also need resistors on the S5 for the fog lights?
Thanks
