Vehicle fitment

Engine code and production dates decide fitment. Model name and year alone don’t.

256 vehicles in 52 model series, inferred

Aftermarket parts that list 030 903 023 EX fit these vehicles according to their supplier catalogues. That does not prove 030 903 023 EX itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
