The man may be correct http://www.rapidonline.com/electronic-components/kingbright-led-bi-colour-red-white-3-65mm-80433 You can get LEDs that are both colours if you reverse the wires.

Would they really fit multi colour LEDs for a job that only requires one colour per vehicle model (GTI/GTD/R)??

I would have thought they would use white LED with a coloured filter on it, to keep production costs down.

I don't know what costs more, making different strips with different colours or one strip with a duel led.

It wouldn't be the first time vw have done this. There's an LED light used in the Audi TT that turns from white to red if you reverse polarity. When wired for red, it must only get 6 volts or it over heats and melts though.

Cebbes is right though.
Switch polarity and voila you get colour change. Assume it is an antipatallel circuit.
