Which cars use the BMW N46B20 engine?

BMW fitted the N46B20 to the BMW E90 320i, BMW E87 120i, BMW E60 520i and BMW E46 318i. These cars were built with this engine from about 2004 to 2012.

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 N46B20 is the only N46 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.
