Vehicle fitment

120 vehicles in 33 model series, inferred

Aftermarket parts that list 3L 121 111 AD fit these vehicles according to their supplier catalogues. That does not prove 3L 121 111 AD itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
