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

188 vehicles in 45 model series, inferred

Aftermarket parts that list 1 721 003 fit these vehicles according to their supplier catalogues. That does not prove 1 721 003 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
