Which cars use the BMW B48B20 engine?

BMW fitted the B48B20 to the BMW G20 330i, BMW G21 330i, BMW G30 530i, BMW G01 X3 xDrive30i, BMW F30 330i, BMW F40 128ti and BMW G22 430i. These cars were built with this engine from about 2015 to 2025.

The badge on the boot is not enough to be sure. The same model name can hide two different engines, for example after a facelift or a change in emission rules. Always read the engine code stamped on the block, or look it up with your VIN.

The B48B20 is the only B48 version we list, which makes it easy to pick, but the wiring and the engine computer still need to match your car.

Not sure? Send us your VIN and your gearbox code. We match the engine family, the year window and the parts on the engine before anything is reserved, and the check is free.
