5.5L V8 (ML63 AMG) - High-performance flagship
Petrol
Listen carefully for any ticking or rattling from the engine bay at cold start, as the M156 6.2L V8 can occasionally exhibit camshaft adjuster or timing chain tensioner wear.
Shift through every gear manually using the steering wheel buttons, ensuring the 7G-Tronic transmission performs crisp, smooth transitions without any hesitation or flaring under load.
Navigate over uneven surfaces or speed bumps to feel for any clunking from the Airmatic suspension, ensuring the compressor is quiet and the vehicle holds its ride height consistently after parking.
Check the infotainment and instrument cluster for any warning lights, particularly related to the complex electronics; verify that the COMAND system and all seat adjustments are fully operational.
Usually marks the point where Airmatic suspension bags or compressors may show signs of natural rubber degradation.
A common window to verify if the transmission valve body has been serviced and the fluid flushed to maintain shifting precision.
A stage where high-performance cooling components and secondary water pumps should be thoroughly inspected for optimal thermal management.
Keep a log of oil changes specifically using Mercedes-Benz approved high-performance synthetic oil to keep the high-revving internals happy.
Periodically clear out the sunroof drains and cabin air intake vents to prevent water ingress, which can be unkind to the onboard electronics.
Ensure the engine coolant and brake fluid are flushed on a strict schedule, as this helps protect the sophisticated aluminium engine components.
Inspect the tires regularly; the ML63’s weight and power can cause uneven wear if the wheel alignment isn't checked every 10,000km.
Keep the battery in peak condition; the W164 chassis uses a vast array of electronic modules that can throw 'ghost' errors if the voltage drops.
Estimated repair costs if issues arise
While the ride quality is superb, the rubber air bellows naturally age. If you find the car sitting low in the morning, it's worth planning for a refurbishment of the struts or the pump.
The 7G-Tronic transmission is robust but complex. If shifting becomes less than perfect, you might eventually need to budget for a professional service or component replacement.
As this is a high-performance AMG model, the braking system is oversized and powerful. When the time comes for a refresh, budgeting for these premium performance parts is a wise move.
