Diesel
While driving at low speeds with the windows down, listen for a 'whine' or 'rattle' from the engine bay, which could be an early sign of turbocharger bearing wear common in higher-mileage M47 engines.
Turning the steering wheel fully to both locks while stationary; check for any whining noises from the power steering pump or heaviness, as these systems can develop leaks as they age.
Observe the exhaust for excessive blue or black smoke upon acceleration; this might suggest oil consumption or clogged crankcase breather systems, which are common to monitor on these diesel units.
Cycling through all iDrive menu functions and climate control settings; ensure the screen doesn't flicker and that the HVAC blower motor operates smoothly across all speeds, as electrical gremlins can occasionally arise.
Usually the time to inspect the condition of the harmonic balancer/crankshaft pulley.
A common point to verify if the timing chain components have been inspected or if the intake manifold swirl flaps have been addressed.
Consider having the turbocharger and ancillary sensors professionally assessed for long-term reliability.
Prioritise regular oil and high-quality filter changes every 10,000km to keep the turbo happy.
Keep a close eye on the coolant levels and check the condition of plastic cooling hoses, as these can become brittle with age.
Ensure the DPF (Diesel Particulate Filter) is functioning correctly by taking the car for occasional longer highway drives to allow for active regeneration.
Regularly inspect the condition of the rear suspension bushings, as these are known to influence the E60's signature smooth ride quality.
Keep the battery in good health, as these models use complex modules that are sensitive to low voltage.
Estimated repair costs if issues arise
If this component shows signs of wear, you might eventually need to budget for a turbo unit replacement to ensure reliable future performance.
Depending on the car's history, it is often recommended to check the intake manifold swirl flaps. Budgeting for a professional removal or replacement kit is a common preventive measure for peace of mind.
To maintain that classic BMW handling, you might eventually need to budget for new control arms or bushings as the suspension components naturally wear over time.
