I have done a cuple of Bi-Xenon retro-fits on A3's, but I have run into a problem trying to code a J519 from a 54 reg 3 door A3.
I believe I need a new J519 module, but as of yet I cannot find a supplier.
Has anyone got a J519 from a 05 reg + for sale? or can anyone point me to a supplier?
Also, is it worth trying Audi to see if they can supply one?
