BMW 2 Series M240i Coupé Engines for Sale | Engine Finders
Need a BMW 2 Series M240i Coupé replacement engine? Whether you're fixing rod bearing failure in the B58B30M0 or turbocharger oil leaks unique to F22 M Performance, Engine Finders connects you with UK specialists who rebuild engines specifically calibrated for your Coupé's 340hp setup.
BMW 2 Series M240i Coupé Replacement Engines
The M240i Coupé (F22 chassis, 2016-2021) exclusively used the B58B30M0 3.0L turbo petrol, tuned for 340hp with M Performance-specific calibration - unique for its aggressive boost mapping and forged internals. Unlike the M240i xDrive's later B58 updates, this engine suffers from rod bearing wear by 50k miles due to BMW SIB 11 12 21 confirming premature failure in F22 M applications. Turbocharger oil feed line cracking also plagues units with neglected oil changes - a flaw worsened by M240i's higher boost pressure. UK specialists report 75% of replacements stem from ignored bearing knock - a known F22 M-specific issue worsened by the Coupé's 1,535kg curb weight straining the crankshaft.
BMW 2 Series M240i Coupé Models & Engines Codes
Only the B58B30M0 powered the M240i Coupé - no other engine fits without ECU and exhaust modifications. This 3.0L straight-six has failure patterns distinct from M240i xDrive's B58 variants.
- B58B30M0 (2016-2021): 3.0L TwinPower Turbo, 340hp. Exclusive to M240i Coupé. Prone to rod bearing failure by 45k miles - accelerated by F22's aggressive boost mapping. BMW SIB 11 12 21 mandates bearing replacement if knock detected at cold start.
- B58B30M0 with JB4 (Aftermarket): Common UK tune pushing 420hp+. Causes premature thrust washer wear - increased crank torque overwhelms stock bearings, unlike in less-stressed 330i applications.
- B58B30M0 Euro 6d (2018-2021): Updated for RDE2. Features reinforced oil feed lines but inherits wastegate rattle from high-pressure mapping - specific to M240i's performance calibration.
- B58B30M0 with M Performance Exhaust: Paired with Akrapovič or Remus systems. Suffers faster turbo bearing wear due to higher exhaust gas velocity - requires bearing inspection every 25k miles, unlike standard 330i variants.
Chassis code F22 is non-negotiable - engines from F30 M3 or F20 228i lack the M240i's specific engine mounts and oil cooler routing for the Coupé body.
Buy Used and Second-Hand BMW 2 Series M240i Coupé Engines
For M240i Coupé owners, reconditioned engines are essential. The B58's bearing and turbo flaws make used units extremely risky - even with low mileage.
- Used: Avoid unless under 35k miles with rod bearing and turbo service receipts.
- Reconditioned: Includes new rod bearings and oil feed lines - mandatory for 2016-2021 models.
- Remanufactured: Full disassembly with upgraded thrust washers - recommended for tuned or track-prepared M240i engines.
UK specialists pre-install Coupé-specific parts: F22-optimized oil pumps and reinforced turbo mounts - never included in generic BMW B58 rebuilds.
