5.4L V12 (M73B54) - Executive Sedan
Petrol
Test the cooling system integrity: While the engine is at operating temperature, carefully check for any coolant odours or signs of seepage around the plastic radiator neck and expansion tank, as these components can become brittle over time.
Evaluate the suspension responsiveness: During your test drive, find a stretch of uneven road to listen for any knocking sounds from the front end, which could indicate that the control arm bushings or EDC shocks may eventually require attention.
Inspect the electrical interfaces: Cycle through the dash display and infotainment screen to ensure all pixels are sharp; fading displays are a common characteristic of these sedans as they age.
Observe the transmission behaviour: During slow-speed manoeuvring, pay attention to the gear changes; the ZF 5-speed transmission typically provides a smooth experience, and any harsh shifting might suggest that the fluid or transmission seals could benefit from a service soon.
Usually the window where secondary air injection systems and vacuum hoses may require a thorough inspection.
A common point to review the condition of the fuel pump and potential wear in the driveshaft flex disc (guibo).
The period where original cooling system components and water pump assemblies are often proactively replaced for long-term reliability.
Prioritise regular engine oil changes to keep the M73 V12 running smoothly.
Keep a close eye on the health of the battery, as these cars are quite sensitive to voltage fluctuations.
Ensure the sunroof drains remain clear to keep the interior upholstery pristine.
Check the condition of the spark plugs and ignition leads periodically to maintain that signature V12 refinement.
Maintain the transmission fluid levels and filter to ensure the gearbox continues to shift with ease.
Estimated repair costs if issues arise
Because the V12 generates significant heat, keeping the cooling system in top shape is vital. If this component needs attention in the future, the estimated cost in NZ is a worthwhile investment to protect the engine's longevity.
To maintain that famous 'magic carpet' ride quality, you might eventually need to budget for refreshing the suspension components. This is a common maintenance task for any E38 of this calibre.
In cars of this age, it is quite common to see minor oil weeping from the valve covers. Addressing this helps keep the engine bay clean and running efficiently.
