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

132 vehicles in 40 model series, inferred

Aftermarket parts that list 31903023B fit these vehicles according to their supplier catalogues. That does not prove 31903023B itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
