Vehicle fitment

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

73 vehicles in 18 model series, inferred

Aftermarket parts that list 03L 903 017 EX fit these vehicles according to their supplier catalogues. That does not prove 03L 903 017 EX itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
