Petrol
Check this by observing the startup sequence. | Description: It is quite important to listen for any rattling during the first few seconds of a cold start, as the M156 engine's camshaft adjusters and lifters can experience wear over time.
While driving on an uneven surface, feel for suspension feedback. | Description: The R63 frequently utilizes the Airmatic suspension system, and it is helpful to monitor for any sagging after the vehicle has been parked for a period, which might indicate aging air struts or a compressor needing attention.
Check this by performing a full lock-to-lock maneuver at low speed. | Description: Power steering rack leaks or whining noises are worth noting, as the complexity of the W251 chassis means these components are tucked away and can be labor-intensive to access.
While driving, monitor the transmission behavior during gear transitions. | Description: The 7G-Tronic transmission is robust but benefits from consistent servicing; it is sensible to look for any hesitation or harsh shifts, which could suggest the valve body or torque converter may eventually require a check-up.
Usually the time to evaluate the health of the suspension bushings and verify the service history of the transmission fluid.
A common interval to check the accessory drive belt, tensioners, and potentially the water pump for optimal cooling performance.
Consider having a specialist inspect the engine mounts and exhaust manifold gaskets to ensure the V8 remains as smooth as intended.
Prioritize high-quality synthetic oil changes every 7,500-10,000km to protect the intricate M156 valvetrain.
Keep a close eye on the coolant reservoir for any signs of contamination or loss, ensuring the cooling system remains top-tier.
Regularly clean the drain tubes near the sunroof and windshield to keep the cabin electronics dry and happy.
Check the brake pad and rotor wear regularly, as the R63's performance nature places a fair bit of work on these components.
Verify the integrity of all rubber hoses and intake components, as New Zealand's UV exposure can cause these to become brittle over the years.
Estimated repair costs if issues arise
Future Budget Planning: While the R63 is a unique machine, the M156 engine can eventually require attention to these internals. It is wise to set aside funds for this specialist work to ensure the engine's long-term health.
Future Budget Planning: Should the vehicle experience a 'leaky' air spring or a compressor issue, it is helpful to budget for a refresh of these units to maintain that signature Mercedes ride comfort.
Future Budget Planning: Depending on the car's driving history, you might eventually need to budget for a transmission electronic refresh, which helps keep those gear changes crisp and responsive.
