I have a 2013 Audi A4 and my DRLs are very yellow and discolored. Recently bought it and it came like this. It definitely kills the face of the car by not being pure white as it should. All my research I've done so far is saying I need to change the entire headlights. No way in hell I'm letting myself buy new headlights just for a slight discoloration.
Anyone else came across this issue and was able to solve it without replacing the entire headlight? I've seen people change the DRL module and more but still have the same issue.
Absolute worst case scenario I'm considering getting it retrofitted with the RGB kit from Morimoto and just leaving it on white all the time. But hopefully someone has more experience with it and actually got it sorted without headache.
