hi, i am in the middle of this retrofit. i already have cupholders and center console multicolor light working, but i have some issues,
the footweels when i open the doors they turns on in white color, but when i start the car the footweels turns off isntead get the color i choose.
strange because when i make the multicolor presentation mode all the lights turns the color correctly.
another problem i have is the contour color option does not appears on the ambint light menu
any help?

We'll need to see an unedited VCDS Auto-Scan to identify how your car is equipped and how you've configured it.

Ambient light in Audi B9/8W cannot be retrofitted successfully without VCP. You need to upload parameters to your BCM.
Only VCDS is not enough.

i got vcp and already download a4_bcm_8w0907063cc.zdc file and upload qq2_ambient_drive select
retrofit is possible because i already have the cup holder and center console working
only the foootweels not work correctly
maybe 09 central electric byte and enable some bit is missing or something

I would have thought that to enable the color changing of RGB footwell lights needs 4 connections not just two?

You need only 3 connections. Pin 3 on rgb fotweel is to supply Lin to another rgb footweel light and pin 4 is just ground

I already solved the problem. a4_bcm_8w0907063cc.zdc and upload all ambient light data, 1,2 and 3. And all the Rgb lights works. Including the contour lights.

I did wonder if the lights were "intelligent" with an embedded LIN slave, but as you say that means 3 connections are needed (power, ground and LIN) not just two as mentioned in your earlier post ;)

I'm also interested in retrofitting ambient light plus on my B9 P+. Did you replace existing LED modules with genuine QQ2 ones, then tweaked VCP & VCDS?

@Top servis - you should start with an autoscan from VCDS so we can see what car you have and how it's configured :)

Ho un a4 b9 ful optional e avevo già le luci bianche ora ho cambiato cablaggio e led grb ho codificato tutto ma le luci pedali non funzionano o meglio funzionano solo quando apri la portiera. Allego un pdf di installazione.
