the bulbs inside the car do not show error on dashboard, in the worst case if they are not with canbus remain lit while driving at very low intensity that does not bother.
Hi, nice video. I have quick question. I was replacing stock w5w bulbs for cheap led ones also from aliexpress but they are flickering for some reason. I see the ones from your video dont have this problem so I'm thinking about ordering ones from your video. But are they "error free" on Audi? Did any bulb related error showed on dashboard after you installed leds?
