Aftermarket part numbers

Supplier articles whose catalogue lists 1J0254502EX. 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.

Models in the manufacturer’s catalogue

Volkswagen Classic Parts lists 1J0254502EX under these models, with the model years of its catalogue sections. It names no engine, so a model here is not proof of fitment: check the part against your vehicle before ordering.

Bora 2003–2005: Bora (1J) 1998–2005 Bora Variant (1J)
Golf (Brazil) 2000–2007

Vehicle fitment

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

39 vehicles in 21 model series, inferred

Aftermarket parts that list 1J0254502EX fit these vehicles according to their supplier catalogues. That does not prove 1J0254502EX itself fits every one: check the engine code, production dates and the supplier’s restrictions on the model series’ vehicle pages.
