4.4L (M62B44) - 740i V8 Luxury Saloon
Petrol
Gently accelerate and decelerate to check if the transmission shifts smoothly, as these ZF 5HP24 gearboxes can experience torque converter wear in high-mileage examples.
With the engine at operating temperature, perform a 'cold start' check or monitor the exhaust for blue smoke, which may indicate worn valve stem seals—a common consideration for the M62 V8.
Find a quiet road and listen for clunks or vagueness in the steering while turning at low speeds, as the heavy front end can place demand on the thrust arm bushings and control arms.
Test every single pixel on the dashboard and center console displays, as these 'ribbon cable' failures are a very common quirk of the E38 interior electronics.
Cooling system overhaul is often recommended if records are absent, specifically the radiator, expansion tank, and water pump.
Timing chain guides should be on your radar for professional inspection, as the plastic guides can become brittle over time.
Suspension refresh, including shocks and bushings, is generally considered to restore the iconic 'limo-like' ride quality.
Keep a close eye on the engine oil level between services, as these V8s appreciate being kept at the optimal mark.
Regularly clean the sunroof drains to ensure rainwater flows away safely rather than entering the cabin.
Use only high-quality coolant, as the M62 engine’s cooling system is quite sensitive to corrosion.
Check the battery voltage periodically, as low voltage can trigger ghost electrical faults across the sophisticated electronic modules.
Ensure the transmission fluid is checked by a specialist who understands the unique requirements of the sealed-for-life ZF units.
Estimated repair costs if issues arise
If this component needs attention in the future, the job involves significant labor to access the front of the engine, but it is a vital part of long-term M62 reliability.
Depending on the car's history, you might eventually need to budget for a complete overhaul including the radiator, hoses, and thermostat to prevent overheating risks common in aging plastic components.
If you notice smoke on start-up, it often indicates the seals have hardened. This is a labor-intensive task, but it keeps the engine running cleanly and prevents oil consumption.
