BMW 540i G30 Engine B58B30C for Sale

Product Overview

For sale is a complete BMW 540i G30 engine, code B58B30C, manufactured in 2020 and recording just 5 kilometres — factory commissioning mileage only.

This is a near-new 2020 unit with the highest quality available outside of new BMW dealer supply, at a meaningful cost saving.

At 5 kilometres, every component — turbocharger, injectors, timing chain, bearings, and all ancillaries — is in factory condition with no operational wear.

BMW Part Numbers

Both part numbers are original BMW identifiers for this engine unit. Buyers can cross-reference either number through BMW dealer systems, TecDoc, or independent parts databases to confirm the engine’s exact specification and compatibility with their specific 540i variant prior to purchase.

About the BMW B58B30C Engine

The BMW B58B30C is a higher-output, multi-application variant within the acclaimed B58 3.0-litre inline-six engine family — one of the most highly regarded modern six-cylinder petrol engines in production. In the 540i G30, the B58B30C produces 245 kW (333 hp) and 450 Nm of torque, providing the progressive, high-revving power delivery that has made the 540i the most popular petrol engine choice in the G30 5 Series range.

The B58 family is a multiple International Engine of the Year award winner, praised consistently for its power output, refinement, efficiency, and tuning potential. The B58B30C variant builds on these foundations with calibration suited to its higher-output applications — incorporating turbocharger and fuelling specifications that differ from the standard B58B30A used in lower-output models. For buyers sourcing an engine with part numbers verified against the original vehicle, this distinction ensures the correct specification is confirmed before purchase.

The RWD / 2WD configuration of this unit is specific to the rear-wheel-drive 540i application. Buyers sourcing an engine for an xDrive all-wheel-drive 540i, or for the X5 45e PHEV application, should confirm that the drivetrain and MHEV system configuration of this engine matches their specific vehicle’s requirements before purchase.
