Before I start, for those not understanding the point of this upgrade here we go:
Xenon headlights have a xenon bulb for the dipped beam, and a halogen bulb for the main beam and for flash. This is most common type of Xenon installation on many cars, not just the A8.
Xenon plus has a single xenon bulb that is used for both dipped beam and main beam, this is done by physically lifting the bulb housing up when main beam is turned on, which is rather cool. There is also an additional halogen bulb in there for 'flash' as a xenon cant warm up fast enough for a quick flash when required. The Halogen also illuminates when on main beam for extra light, and if dipped beam is on, then when you flash you get the halogen on and the xenon bulb lifts.....
ok, on with the install...
Here is the donor car with factory Xenon plus.
and here is my car. The bumper is off from earlier frolics I've had with the starter motor, and to be honest as its 2 bolts, 1 electrical connector and 1 headlampwash pipe I'd be tempted to remove it as it does make it easier as things progress.....
So, first we need to remove the lights... There are 2 crosshead screws at the top of each headlight under these black covers. Pop the covers off with a flatblade, then undo the crosshead screws. If you have regular xenons, note the extra cable as indicated by the arrow - This makes more sense in a short while:
and here we have the donor car with Xenon plus - Note, no extra cable, instead we have a silver box bolted to the side of the headlight unit:
and there are two crosshead screws under here too. They are a real bitch to get to if the bumper is on, and putting them back with the bumper on is nearly impossible... If you have an undertray, be prepared to go fishing for the screws plenty of times during this procedure...
And here on my car with the bumper removed, a bit easier to see:
Once all 4 screws are removed, you can disconnect the main 10 pin black wiring block, the seperate indicator connector and on the regular xenons, the 4 way connector on the side, then the headlight will come out. It will come out with the bumper in place with some careful wiggling, but again bumper off is way easier...
