Petrol
Check this by inspecting the cooling system: While the engine is cold, look for any signs of pink or blue residue around the radiator hoses and the plastic expansion tank, as these housings can become brittle over time.
Listen closely for any knocking or clunking sounds from the front suspension, as the control arm bushings are known to wear out eventually in heavier coupes driven on uneven NZ roads.
Ensure the ZF 8-speed automatic transmission shifts smoothly between gears; if you feel any hesitation or jerking, it is worth asking to see if the transmission fluid has ever been serviced.
Check this by operating the frameless windows: Raise and lower them repeatedly to ensure the seal is tight against the door frame, as these seals occasionally need adjustment to keep the cabin quiet and dry.
Usually marks the point where spark plugs and cabin air filters should be replaced to keep the B48 engine running efficiently.
A common interval to check the serpentine belt and tensioner, and to consider a preventative flush of the cooling system.
Often recommended for a transmission fluid and filter service to ensure the gearbox continues to offer that crisp, smooth feeling.
Keep a consistent log of oil changes every 10,000km or annually to look after the turbocharger's longevity.
Regularly inspect the tyre tread depth, as the F22's rear-wheel-drive setup can be quite enthusiastic with rear tyre wear.
Check the engine oil level via the iDrive system periodically, as these engines are designed to be quite efficient and appreciate being kept at the top of the measurement range.
Keep the drainage holes near the windscreen scuttle clear of leaves and debris to prevent water ingress into the cabin electronics.
Ensure the battery health is monitored, as modern BMWs are quite sensitive to voltage drops and prefer to be kept on a charge if the car sits for long periods.
Estimated repair costs if issues arise
If this component needs attention in the future, it is a standard preventative maintenance task for the B48 platform to ensure optimal cooling performance.
Depending on the car's history, you might eventually need to budget for a refresh of the front control arms to restore that sharp, factory-fresh steering feedback.
If you decide to keep the vehicle for many years, performing a transmission oil and pan-filter service will help protect the longevity of the ZF gearbox internals.
