Vehicle fitment

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

68 vehicles in 19 model series, inferred

Aftermarket parts that list 7 521 488 fit these vehicles according to their supplier catalogues. That does not prove 7 521 488 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
