"My dealership didn't see it as their issue as Audi UK stated they were removing it from spec and it was just tough."
Chances are they've a clause on the order form which says that they can deliver the car with the spec current at the time of manufacture. Mine does.
However if I generate a
current spec on the Audi UK website it comes out with illuminated sills (I presume that's "puddle lights") and the extended ambient lighting, so they can't use that one if they aren't fitted.
"i'd probably push them for a retrofit at my expense." - what a kind an generous offer, I'll certainly push for a retrofit at your expense (just kidding
).
