5.5L V8 Bi-Turbo (CLS 63 AMG) - RWD
Petrol
Gently accelerate and decelerate at lower speeds to feel for any hesitation or clunking in the MCT transmission; these are complex gearboxes that appreciate smooth inputs.
Turn the steering wheel to full lock while stationary; listen for any whining sounds from the power steering pump, as these high-performance units can be sensitive to fluid degradation.
Navigate over a few bumps and listen for any suspension rattles or knocking; the Airmatic suspension is brilliant but can show its age through worn bushings or leaking struts on higher-mileage examples.
Check the infotainment and instrument cluster for any flickering or dead pixels; these electronic systems are feature-rich and benefit from a solid battery, so check that the car starts promptly without hesitation.
Usually the time to evaluate the health of the air suspension components and inspect the cooling system hoses.
A key interval where spark plugs and transmission fluid servicing become essential to maintain that characteristic M157 V8 performance.
Consider having a specialist inspect the engine mounts and accessory belt tensioners to ensure everything remains tight and quiet.
Prioritize a pre-purchase inspection from a specialist who has specific experience with Mercedes-Benz AMG engines.
Keep a close eye on your engine oil levels between services, as these Bi-Turbo engines can consume a small amount of oil depending on driving style.
Ensure the cooling system is kept in top condition, as the V8 generates significant heat that relies on efficient radiator and pump performance.
Regularly monitor your brake pad and rotor thickness, as the stopping power required for a vehicle of this size does consume consumables at a faster rate.
Maintain the battery health, perhaps using a trickle charger if the car is sitting for extended periods, to keep the complex electronic systems happy.
Estimated repair costs if issues arise
If this component needs attention in the future, the estimated cost in NZ is reflective of replacing the air bellows or compressor, which help maintain that signature smooth ride.
Depending on the car's history, you might eventually need to budget for a comprehensive transmission flush and service to keep the gear changes crisp and responsive.
Given the performance capabilities of the CLS 63 AMG, you should prepare for the eventual cost of high-performance braking components when the time for a refresh arrives.
