Dont know if this is related to what Ive ben doing with the CH/LH mod but here goes. L/H numberplate LED stopped working and as the screw had rounded off went to the Audi garage to buy 2 more holders so I could replace both together. After cutting it off the car LED bulb popped back the holder and fitted to the car.......no illumination. I then changed the R/H holder with the same LED bulb and now that doesnt work either. Ive tried turning round the bulb for polarity reasons and swapped sides but both sides no longer work.......I had a look at the side fusebox but nothing blown. Kinda stumped now. Anyone had this before. Could it be that the 2 LED bulbs have gone???? Now going to rip my garage apart to find the bag of normal bulbs that I took out when I did the LED conversion.
