3.0L (B58) - M240i xDrive Performance
Petrol
Test drive task: Perform a low-speed, full-lock turn in a quiet parking lot. | Detail: Listen for any clicking or binding sounds from the front differential, as the xDrive system is robust but can exhibit wear if the vehicle has been driven aggressively.
Test drive task: Check this by idling the car for 5 minutes after a brisk drive. | Detail: Observe the underside for any signs of weeping around the B58 oil filter housing, which can occasionally develop a slow seep in higher-mileage examples.
Test drive task: While accelerating firmly in Sport mode, monitor the transmission behavior. | Detail: The ZF 8-speed is excellent, but ensure shifts are crisp without hesitation, as neglected fluid changes can lead to less responsive gear changes over time.
Test drive task: Inspect the front tyre wear patterns before and after your drive. | Detail: Due to the M240i’s performance orientation, ensure the tread wear is even; uneven wear could suggest past alignment issues or spirited handling of the chassis.
Consider a proactive transmission fluid flush to ensure the ZF gearbox remains smooth.
A common point to evaluate the condition of the spark plugs and ignition coils to maintain B58 engine efficiency.
Assess the suspension bushings and dampers, as New Zealand roads can contribute to premature wear on performance-tuned setups.
Stick to the BMW Condition Based Service (CBS) schedule, opting for oil changes every 10,000km rather than stretching the manufacturer's maximum interval.
Regularly clear out the drainage channels around the windscreen and sunroof to prevent moisture ingress.
Verify that the cooling system is topped up with the correct BMW-spec coolant, as the B58 runs at specific temperatures for optimal performance.
Check the brake pad sensor status via the iDrive menu to plan your next brake service well in advance.
Ensure the infotainment software is up to date during your dealer or specialist visits to keep the connected drive features running smoothly.
Estimated repair costs if issues arise
In cars of this age, it's common to consider that these components may eventually require replacement to maintain optimal cooling efficiency. Depending on the car's history, you might eventually need to budget for this work to avoid overheating issues.
If you notice subtle vibrations or clunks during gear changes in the future, the rear subframe or differential bushings may need attention. It's a standard part of owning a high-torque performance vehicle.
Because the M240i is quite capable, high-quality rubber is essential for safety. If this component needs attention in the future, the estimated cost in NZ for a premium set can vary based on your preferred brand.
