4.4L S68B44 - M60i
Petrol
While at a standstill in Neutral, listen for any subtle high-frequency chirps or vibrations during cold start transition. | Note: The S68 is a complex bit of engineering, and while robust, it is worth monitoring the idle quality when the engine is transitioning from cold to operating temperature.
Check this by navigating through the iDrive 8/8.5 screen extensively while driving on a bumpy road. | Note: With the LCI shift to a curved display and touch-heavy interface, ensure the screen responsiveness remains consistent and doesn't flicker when encountering road vibration.
While driving in 'Sport' mode, observe the transmission's eagerness to downshift during low-speed merging. | Note: The 8-speed ZF gearbox is generally bulletproof, but ensuring the software mapping feels sharp and responsive is a good way to gauge overall transmission health.
Check this by performing a low-speed maneuver into a tight parking space to test the mild-hybrid system engagement. | Note: The 48V mild-hybrid integration should be seamless; any jerkiness during the auto start-stop transition is worth noting for your service technician to inspect.
Recommended major inspection of cooling system hoses and auxiliary belt health.
Consider a transmission fluid flush and filter replacement to maintain the longevity of the ZF gearbox.
Check the condition of the air suspension components and compressor output if equipped.
Prioritize oil changes every 10,000km regardless of the factory service interval to keep the twin-turbochargers happy.
Inspect the coolant levels regularly; the S68 utilizes a complex split-cooling circuit.
Keep an eye on tire wear patterns, as the heavy kerb weight of the M60i can be quite eager to wear inner shoulders on performance-oriented alignment settings.
Ensure the infotainment software is updated at the dealership to prevent minor bugs in the latest iDrive iterations.
Always allow the engine to reach operating temperature before utilizing the full potential of the M-tuned performance.
Estimated repair costs if issues arise
Future Budget Planning: While these units are designed to be long-lasting, as the vehicle ages, the advanced battery management system may eventually require a professional diagnostic or potential replacement.
Future Budget Planning: If your model is equipped with two-axle air suspension, it is worth keeping a rainy-day fund for potential strut or compressor refreshes once the vehicle passes higher mileage brackets.
Future Budget Planning: Depending on your driving style, the M60i heavy-duty braking system will eventually require maintenance. Replacing these larger performance rotors is a significant but necessary task to maintain safety.
