253 vehicles in 77 model series, inferred

Aftermarket parts that list 03C 121 666 fit these vehicles according to their supplier catalogues. That does not prove 03C 121 666 itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
