DRL '' retrofit '' in the headlight with P21W

[M-A8]

Hi
This isn't a breaking news or something what wasn't done before I believe coz I can't be the first one with my average skills but I will share it anyway

I've just finished retrofitting Bi-xenon cornering AFS headlights (still wiring the AFS modules so not quiet completed yet) and first thing I couldn't stand were the halogen DRLs
Ugghhh, so ugly.

So, I've spent £41 on LEDs, plus some scotch locks, VCDS and I was ready to enjoy the awsome difference.

First of all I ordered some P21W CREE LEDs


and some 501 SMD LEDs (very important to get this exact construction 501s, will explain later)


The next obvious thing I did is I swapped the original 501s and P21Ws with the LEDs above.

Then there is a little trick which enables DRLs at all the time (VCDS lets you switch them on and off via MMI) and dims them when you switch the main beam, basically they will work exactly as original headlights with LEDs just follow this steps.

Get the 2 scotch locks per headlight and connect sidelight's positive wire with DRL's positive, sidelight-red DRL-white, like that

Then put everything back together (and I do not remover wheel arches or reservoir, only air box for this ''upgrade)

Then connect VCDS and go to Central Electronics [09], then to Coding [07] and change 3rd digit to 3 ---> Bi-xenon headlights with LED DRL.

Also you can select if you want DRLs to be included in MMI menu.

Click DO IT then close controller and you done

NO resistors
NO errors
NOTHING

And the effect:
