E63 S AMG 4.0L Biturbo V8 AWD
Petrol
Perform a cold start and listen for a rattling sound from the engine bay. It is helpful to consider that the M177 V8 engine's timing chain tensioners can sometimes show wear in vehicles with higher usage, so a smooth startup is a good indicator of overall health.
Switch the driving mode to 'Comfort' and navigate over some uneven pavement. It is worth noting that the air suspension (Airmatic) is a complex system, and monitoring for any sagging or uneven ride height when parked overnight can provide insight into the status of the air struts.
Gently apply the brakes at varying speeds. Given the high-performance nature of the carbon-ceramic or performance steel brakes on the E63 S, it is common practice to check for any pulsing or squealing, which might suggest that the heavy-duty components are nearing the end of their service interval.
Engage 'Sport+' and perform a few moderate accelerations. It is advisable to observe the transmission shifts; in cars of this caliber, the MCT (Multi-Clutch Transmission) should feel sharp, and any consistent hesitation could suggest it may benefit from a software update or fluid service.
Usually marks the first major service interval, often including spark plug replacement and fresh fluids to keep those turbochargers running efficiently.
A common point to review the auxiliary drive belts, coolant pump health, and potential suspension bushing wear, which helps maintain that signature planted feel.
Typically when a proactive review of cooling system components and major drivetrain mounts is recommended to preserve the drivetrain's refinement.
Ensure the service history shows regular, specialist-led oil changes using high-grade synthetic oil to protect the precision-engineered biturbo internals.
Keep an eye on the coolant levels and look for any signs of seepage around the engine bay, as cooling efficiency is vital for high-output engines.
Regularly inspect the tire treads for uneven wear patterns, as the alignment settings on the E63 S are quite aggressive and can affect longevity.
Check that the panoramic sunroof seals are clean and lubricated to prevent wind noise or drainage issues during New Zealand's wetter months.
Verify that all infotainment software and vehicle firmware are up to date, as Mercedes-Benz often releases enhancements that can improve system stability.
Estimated repair costs if issues arise
While these units are robust, if one were to require attention in the future, it is wise to prepare for the cost of sourcing and fitting a genuine or high-quality OEM strut to maintain the car's dynamic handling.
If the vehicle is equipped with the performance brake package, depending on how the car has been driven, you might eventually need to budget for a complete set of rotors and pads, which are significant performance components.
In high-torque vehicles like the E63 S, these mounts can experience wear over time. If you notice increased vibration, budgeting for these ensures the car retains its smooth, luxury-sedan driving experience.
