Petrol
While idling in Park, listen for a rhythmic 'ticking' from the top of the engine, as the VANOS system and timing chain guides are known to be wear items in high-mileage M62 engines.
Gently accelerate and brake to observe the front suspension; check for any shimmy in the steering wheel, as the E38 chassis is sensitive to control arm bushings and thrust arm play.
Operate every window and sunroof function repeatedly; these models often develop issues with window regulators and the complex sunroof cassettes due to age-related plastic fatigue.
Before turning the engine on, inspect the dashboard for 'pixel bleed' in the instrument cluster or the MID display, which is a common characteristic of these BMW electronics as they age.
Cooling system overhaul, including radiator, water pump, and thermostat housing.
Timing chain guides and valley pan gasket inspection becomes crucial for engine longevity.
Suspension refresh, including shocks, struts, and all rubber bushings.
Keep a close eye on the cooling system; these V8s run hot and appreciate fresh coolant and a healthy radiator.
Ensure the oil changes are performed regularly using high-quality synthetic oil to keep the VANOS system happy.
Check the battery voltage periodically; E38s are notoriously sensitive to low voltage, which can cause phantom electronic gremlins.
Keep the sunroof and door drains clear of debris to prevent water ingress into the cabin electronics.
Regularly inspect the vacuum lines and intake manifold gaskets, as these can become brittle and lead to rough idling.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is higher due to the labor-intensive nature of the job, which involves removing the front timing covers.
Depending on the car's history, you might eventually need to budget for a full cooling system overhaul to prevent overheating, including hoses, the radiator, and the water pump.
If you notice vague steering or clunks over bumps, you might want to plan for a refresh of the front control arms and thrust arms to restore that classic BMW handling feel.
