I had to restore the lights in the A4 because the reflector in the projector was scorched from the heat off the halogen. So the A4 now has a full conversion, side, dipped, main, fog, indicators) to LED (few pics below). The dipped beam LED's are quoted at 9000 lumens pair. Their actual output is better than halogen but below a good set of OEM Xenon's.
I have thought about retro fitting the D3 but the bulb monitoring of the central electronics module would be throwing all sorts of warnings - of which is an MOT failure - this brings me back to a project I have sitting in waiting. Also, the LED aftermarket tech isn't up to the standard to be better then OEM Xenons yet. So as others have said, get a new set of Xenons.
