'06 audi a3

any one know how a vac com works? i need to reprogram the rear lights and it is said a vac com program is needed. where do i get said vac com?



any one converted a car from euro lights to us? any ideas on where to go for help? the audi dealers are clueless, and dont want to touch a non native car.

sorry its called Vag Com.
