Vehicle fitment

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

96 vehicles in 46 model series, inferred

Aftermarket parts that list 03C903023 fit these vehicles according to their supplier catalogues. That does not prove 03C903023 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
