Petrol
Gently accelerate and decelerate while listening for any 'clunking' from the rear; this is a good way to assess the condition of the subframe bushings, which are known to soften over time.
Keep an eye on the coolant temperature gauge during your drive; it's helpful to ensure it remains stable, as the cooling system components on these models can become brittle as they age.
Operate the window switches and central locking system, as the convenience electronics may occasionally show their age in older BMWs.
While parked, turn the steering wheel lock-to-lock to feel for any stiffness or unusual noises, which can indicate that the power steering hoses or pump might eventually require a freshen-up.
Usually the time to ensure the suspension bushings and ball joints have been inspected for wear.
A common point to verify that the timing chain guides have been assessed, as they are a significant part of the engine's longevity.
Typically a stage where auxiliary engine components like the alternator and water pump may benefit from a check-up.
Check for any service records showing recent oil changes using high-quality synthetic lubricants.
Inspect the radiator expansion tank and hoses for any signs of surface cracking.
Verify that the engine runs smoothly at idle when cold, which is a sign of a healthy vacuum system.
Confirm that the air conditioning system blows cold air effectively.
Take a look under the engine bay for any signs of minor oil seepage around the valve covers.
Estimated repair costs if issues arise
Because these engines operate at specific temperatures, it is wise to eventually refresh the radiator, expansion tank, and thermostat to prevent future overheating. You might eventually need to budget for this to ensure peace of mind during longer trips.
In the M62 engine, the internal guides are a known long-term maintenance point. If this component needs attention in the future, it involves a significant amount of labor to reach the timing cover, so it is helpful to keep this in your Future Budget Planning.
To maintain that classic 'BMW feel' on Kiwi roads, the control arms and bushings may eventually require replacement as they naturally wear out. Depending on the car's history, you might eventually need to budget for a suspension refresh.
