Hello!
I wanted to tell you that I've finally retrofitted to facelift my car with full led headlights! Everything works perfectly and without any error neither on the dashboard nor on VCDS!
I'll try to explain the procedure in as much detail as possible.
I originally had Xenon headlights.
While doing my research, I came across this video: Youtube : youtu.be/r7kxjbLNNto
In the video you can see that it was another guy, an Italian, who did all his retrofitting. So I contacted the Italian guy and he agreed to help me. You have to realise that it's quite complicated...
You need to buy a new 55 module (auto-leveling), which the Italian programs with VCP (so you send it to him and he sends it back to you), and you also need to modify the plug wires for this module, adding a wire from this module to the BCM.
You also need to modify the headlight plug and add a wire in addition to the fuse box to each headlight.
All this is explained in the video, now it's the part that isn't explained in the video!
In fact, the Italian connects to your PC with VCDS, code and, above all, makes lots of adaptations to the 55 module and the headlights.
If you have purchased headlights with factory-fitted ballasts for this headlight,, everything should work straight away!
If, like me, the ballasts do not come from these headlights, you will need to recode the ballasts... Fortunately, I managed to get hold of a VAS and an ODIS (clone but it works), and by buying a 1h session with Geko, you can do reprogramming online as if you were doing it at Audi! You can also unlock components etc... I think it is possible to program module 55 in this way without shipping the module to it.
I know a bit about VCDS, and I could have done the operations myself with the procedure to follow, but, of course, Italian doesn't give you the procedure
The same goes for online coding with ODIS, I could have done it, its didn't look very complicated, but you need to know where to click.
And that's it, my car is now a Facelift
How much did it cost? Here are the expenses:
Headlight : 1 110€
Module 55 : 39€
Italian : 370€
Session Geko : 24€
Bumper : 400€ + 150 (paint)
Total : 2 093€
On the other hand, I sold :
Xenon : 400€
Bumper : 265€
Total : 665€
2093 – 665 : 1428€
It's up to you to decide whether it's worth it
Sorry for my English
