4.0L (M177) Biturbo V8 - Luxury Performance
Petrol
While accelerating steadily in Comfort mode, check for any hesitant shifts from the 9-speed MCT transmission; it is common for these to feel a bit firm, but they should never shudder or hesitate.
Check this by idling the car for five minutes, then gently revving; watch for any puff of blue or grey smoke from the exhausts, which can be an early sign of potential turbo seal wear on high-output engines.
While navigating a slow-speed turn with the steering at full lock, listen for any clicking or binding from the front suspension, as the complex AMG steering geometry can eventually show wear in the bushings.
Before finishing your drive, toggle through all suspension settings (Comfort, Sport, Sport+) while stationary; ensure you can hear and feel the air suspension system actively adjusting to avoid potential compressor or strut issues.
Consider a full transmission fluid and filter service to keep that MCT box shifting precisely.
It is often wise to inspect the engine and transmission mounts, as the massive torque can put significant stress on these components over time.
Recommended interval for a comprehensive cooling system health check, including inspecting the charge air coolers.
Keep a close eye on your oil levels, as these performance V8s appreciate a top-up between scheduled intervals.
Ensure your brake pad and rotor thickness are checked regularly; the performance braking system is fantastic but wears according to your driving style.
Stick to the service schedule strictly using approved high-performance synthetic oils to protect those twin turbos.
Keep the vehicle's software updated at an authorized service center to ensure the engine management and infotainment systems are running optimally.
Regularly clean the drain paths around the windscreen area to prevent any moisture buildup near the sensitive cabin electronics.
Estimated repair costs if issues arise
If your chosen E63 S is equipped with the Carbon Ceramic option, it is helpful to keep in mind that these have a long life but are significant investments to replace when the time comes.
In cars of this age, it is worth keeping a small reserve, as air suspension components may eventually require refurbishment to maintain that perfect AMG ride quality.
Depending on the car's history, you might eventually need to budget for a replacement of the auxiliary cooling pump, which ensures the turbos stay within safe temperature limits.
