Diesel
Turn the steering wheel fully to the left and right while at a standstill; listen for any 'whining' or groaning noises, as these N47-engine era cars may eventually show signs of power steering pump fatigue.
Gently accelerate from a standstill on a slight incline to observe the transmission; ensure the gear changes in the automatic models feel smooth rather than jerky, which helps identify if the transmission fluid may be due for a service.
Opening the bonnet while the engine is idling and listening for a light rattling noise near the back of the engine block, as this can be a helpful indicator to check the service history for timing chain maintenance.

A common point to review the condition of the suspension bushings and shock absorbers to maintain that signature BMW ride quality.

Keep an eye on the digital service history within the iDrive system to track previous owner care.
Use high-quality diesel fuel and consider a bottle of fuel system cleaner occasionally to keep the injectors in good health.
Ensure the panoramic sunroof drains are kept clear of debris to prevent any potential water ingress during heavy NZ rain.

Depending on the car's history, you might eventually need to budget for a DPF professional clean or replacement if the vehicle has primarily been used for short city trips, which can lead to soot build-up.
If you notice a slight lack of sharpness in handling over time, you may eventually need to budget for replacing worn control arm bushings or shock absorbers to restore the driving experience.
