2019 — 2024
2.0L I4 (B48A20)
Petrol
Full-throttle acceleration from a low speed in a straight line. | Note: Listen for excessive front-wheel scrub or 'torque steer'. While xDrive, the F40 chassis is front-biased and can feel unsettled compared to older RWD BMWs.
Low-speed crawling and repetitive shifting between Drive and Reverse. | Note: Assess the Aisin 8-speed automatic for jerkiness or 'thumping'. It is generally reliable but less smooth than the ZF units found in RWD BMWs.
Visual inspection of the coolant expansion tank and surrounding hoses after the engine is hot. | Note: The B48 engine is prone to hairline cracks in the plastic coolant vent pipes and reservoir; look for white crusty residue or a sweet smell.
Execute tight 'Figure-8' turns in a quiet parking lot. | Note: Listen for clicking or binding sounds. Early xDrive transfer cases in this generation can occasionally exhibit binding if tyre circumferences are mismatched.
Comprehensive cooling system refresh (water pump and thermostat) and inspection of the front control arm hydraulic bushings for leaks.
Standard synthetic oil service and microfilter replacement; check for any early software recalls regarding the iDrive 7 system.
Major service including high-performance spark plugs, air filter, and a preventative flush of the xDrive transfer case fluid.
Oil and filter changes every 10,000km or 12 months, ignoring the optimistic 30,000km factory interval.
Bi-annual brake fluid flush to maintain the integrity of the M-Sport braking system.
Regular intake valve cleaning (walnut blasting) every 60,000km to combat Direct Injection carbon buildup.
Strict adherence to 'Star-Rated' BMW tyres to ensure xDrive rolling circumference remains within 1% tolerance.
Battery health check; the high electronic load of the F40 1-Series requires a strong AGM battery.
Estimated repair costs if issues arise
Genuine BMW parts are expensive; high-performance Brembo-equivalent kits are slightly cheaper in NZ.
The xDrive system is sensitive to tread depth differences; it is often recommended to replace all four at once.
Replacing the water pump and plastic housing is a labor-intensive job requiring the removal of عدة intake components.
