Aftermarket part numbers

Supplier articles whose catalogue lists 3B0 131 702 BA. Check the supplier’s own restrictions before ordering. A fitment condition under a part number is one its supplier names for at least one of the vehicles the part is listed for, not for all of them: a vehicle’s page shows which apply to it.

What these parts’ suppliers state

Each value belongs to the part number beside it, not to the OE number: parts that list one OE number can differ. Where your vehicle manufacturer gives a value, it takes precedence.

Vehicle fitment

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

74 vehicles in 25 model series, inferred

Aftermarket parts that list 3B0 131 702 BA fit these vehicles according to their supplier catalogues. That does not prove 3B0 131 702 BA itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
