4.4L S63B44 - X5 M Competition
Petrol
Check this by inspecting the cooling system: While the engine is cold, look for any signs of coolant residue around the plastic expansion tank and hoses, as the S63 engine generates significant heat that can age these components over time.
While driving at low speeds, listen for any light ticking or clunking from the suspension: The X5 M Competition features complex adaptive components, and it is helpful to verify that all bushings feel firm and compliant during your test drive.
Perform this test by cycling through all driving modes: Toggle through the M1 and M2 settings while at a standstill to ensure the air suspension adjusts smoothly without any warning messages on the dash.
Check the service menu specifically to ensure that the previous owners have adhered to strict oil change intervals, as the S63 engine thrives on clean, high-quality lubrication.
Usually marks the point where secondary cooling system check-ups and preventative gearbox oil service conversations begin.
A common window to assess the condition of the brake rotors and pads, as well as checking the drive belts for signs of wear.
Typically the time to inspect the spark plugs and coils to ensure the ignition system remains sharp and efficient.
Prioritize strict oil change intervals every 10,000km or annually to keep the twin-turbochargers happy.
Keep the engine bay tidy to make it easier to spot any minor fluid weeping early on.
Regularly verify the coolant level, as these high-performance systems appreciate being kept at optimal levels.
Use premium 98 octane fuel to ensure the engine management system operates as intended.
Ensure the air filters are replaced on schedule to maintain that signature M-Power intake performance.
Estimated repair costs if issues arise
In cars of this age, it is common to consider the electric auxiliary pumps that keep the turbos cool after shutdown. If this component needs attention in the future, the estimated cost in NZ is to account for the pump unit and labour.
The air suspension provides an incredible ride, but depending on the car's history, you might eventually need to budget for refreshing the struts or compressor to maintain that factory-fresh comfort.
Given the performance capabilities of the X5 M, the braking components are substantial. When it comes time for a full set of pads and rotors, it is wise to set aside funds to ensure you are using high-quality replacements.
