Since the 4G0-035-223-C is part of the same VAG family as the 4G5 we discussed, it also crosses over to the Porsche Macan and Panamera Bose systems. In 2026, these are highly sought after by Porsche owners because the dealership price for a new unit is significantly higher than the Audi-branded equivalent.
