BMW OE number, as listed in aftermarket supplier catalogues. Compare listings for this exact number, then confirm the part number and vehicle fitment before ordering.
Supplier articles whose catalogue lists 1 157 391. 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.
Engine code and production dates decide fitment. Model name and year alone don’t.
