How to Tell If Your BMW Has a B58 Engine

VIN Decoding and Engine Code Check

The quickest way to confirm a B58 is to decode the VIN. BMW VINs use the 4th through 7th characters to identify the model and engine. You can run your VIN through a free BMW VIN decoder or a service like a dealer parts counter. Under the hood, the engine cover on a B58 typically reads ‘TwinPower Turbo’ and the oil filter housing sits at the front of the engine. If you have the engine code stamped on the block, B58B30M0 is the original and B58B30M1 is the TU. When in doubt, check the emissions sticker or build sheet for the engine designation.
