Hi I've finally got round to getting a NEW set of RS6 BiXenon AFS headlights fitted to my car - to replace the same spec A6 lights already fitted - but without the DRL's obviously. They look superb, but the DRL's do not dim when the xenons are on? Is this something easily fixed? Can an Audi technician do this if given the recoding steps to take? Or do I simply need to buy a new/correct module?? Any help appreciated Thanks.
