5.5L V8 Bi-Turbo - RWD (M157)
Petrol
Observe the gear shifts while driving at low speeds | Observation: In the 7-speed MCT transmission, it's worth noting if the downshifts feel clunky or jerky, as these transmissions occasionally benefit from a software recalibration or fluid service as they age.
Check the Airmatic suspension via the ride height button | Observation: When cycling the suspension through its modes, listen carefully for any persistent hissing sounds; it's quite common for the air struts or compressor to show signs of wear on a vehicle of this age.
Examine the engine bay during a cold start | Observation: Listen for any distinct rattle during the first few seconds of ignition, as it is prudent to be aware of the timing chain tensioner condition on the M157 engine.
Inspect the braking performance during gentle stopping | Observation: Ensure there is no vibration through the steering wheel or pedal, as the large composite rotors fitted to the AMG models can develop wear patterns that you should keep an eye on.
Usually marks the interval for transmission fluid and filter service.
A common point to inspect the auxiliary drive belt, tensioners, and potentially the cooling system components.
Often the time to evaluate the health of the suspension air struts and potential vacuum line integrity.
Prioritize regular engine oil changes every 10,000km using high-quality synthetic oil to protect the bi-turbo components.
Keep a close watch on coolant levels, as the M157 runs quite hot and the cooling system hoses can age over time.
Regularly clean the drain holes around the windscreen and sunroof to prevent water ingress into the cabin electronics.
Ensure the COMAND infotainment system is updated and functioning smoothly during your ownership.
Consider a professional pre-purchase inspection from a specialist who has experience with AMG-specific chassis electronics.
Estimated repair costs if issues arise
If the ride height begins to sag or the compressor works overtime, you might eventually need to budget for strut replacement to ensure the car maintains its signature smooth ride.
Given the performance capabilities of the S63, the braking components are heavy-duty; when the time comes to refresh them, planning ahead for these high-performance parts is a wise move.
To keep the V8 running at optimal temperatures, it is common to refresh the water pump and associated gaskets as a proactive measure for long-term reliability.
