4.4L (S63) V8 Twin-Turbo - M xDrive AWD Sedan
Petrol
During low-speed maneuvering, listen for any 'clunking' from the suspension, as the complex F90 M5 front axle components can show signs of wear as they approach higher mileage.
Check the iDrive infotainment system by navigating through all menus while the engine is running to ensure no glitching or screen flickering, which can indicate battery or grounding health.
Observe the transmission behavior in 'D' mode while coming to a stop; it should be smooth. If you notice harsh downshifts, it may be worth checking the history to see if the transmission software has been updated.
Perform a cold start and check for any excessive blue smoke or unusual rattling from the engine bay, as the S63 V8 requires a very disciplined warm-up cycle to maintain its longevity.
Usually marks the time to consider a transmission oil service and fresh spark plugs to maintain that sharp throttle response.
A common point to have the differential fluids and the coolant system inspected, as these systems handle significant heat and torque.
Consider a comprehensive review of the active suspension dampers and verifying the status of the turbo cooling lines.
Use only high-octane 98 fuel to prevent engine knock and ensure the fuel injection system stays in peak condition.
Prioritize oil changes every 10,000km or annually, regardless of what the on-board computer suggests, to keep that S63 engine happy.
Keep a close eye on your brake pad and rotor thickness, as the M-Compound brakes are high-performance parts with specific wear characteristics.
Verify the coolant levels regularly, as the F90 uses a complex cooling system with multiple circuits that need consistent maintenance.
Ensure the electronic parking brake is fully functional, as it is a common point to check during routine warrant of fitness inspections.
Estimated repair costs if issues arise
Given the heat generated by the twin-turbo V8, it's wise to plan for potential cooling system refreshes as the car ages. This helps prevent overheating and keeps your engine running efficiently.
These performance brakes offer incredible stopping power, but they are wear items. Depending on your driving style, it's helpful to keep some funds aside for when the friction material eventually thins out.
The M5's handling prowess comes from advanced tech. While durable, it's worth noting that if you eventually feel a change in ride quality, a component refresh might be needed to restore that factory-fresh feeling.
