133 vehicles in 58 model series, inferred

Aftermarket parts that list 03C 121 026 AS fit these vehicles according to their supplier catalogues. That does not prove 03C 121 026 AS itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
