6.2L V8 (CLS 63 AMG) - RWD
Petrol
Gently press the brake pedal while at a stop to feel for any judder, as the large AMG brake discs can become warped or suffer from wear, which is a common observation on these heavy performance sedans.
Listen closely to the engine idle with the bonnet open; check for any rhythmic ticking sounds, as the M156 6.2L V8 can occasionally display signs of cam phaser or lifter wear which is worth investigating through a pre-purchase inspection.
Navigate over a series of speed bumps at low speeds to ensure the Airmatic suspension rises and lowers promptly, as aging air struts and compressors are components that often require attention on vehicles of this vintage.
Operate the 7G-Tronic transmission through all gears under moderate load to ensure shifts are smooth, as the valve body and conductor plate can sometimes show signs of needing a service or refurbishment in older units.
Time to inspect suspension bushes and ball joints for perishing.
Recommended interval for a thorough transmission fluid and filter service.
General window to check the health of the cooling system components including radiator hoses and the water pump.
Keep a consistent log of the engine oil level, as these high-performance V8s are known to enjoy a top-up between regular service intervals.
Ensure the engine air filters are replaced at the recommended intervals to keep that iconic 6.2L engine breathing perfectly.
Check the condition of the rear tyres regularly, as the CLS 63 AMG's torque can make quick work of them.
Maintain a schedule for brake fluid flushes to keep the stopping power sharp and the lines clear of moisture.
Periodically check the electrical battery health, as these cars have many sophisticated modules that prefer a stable voltage.
Estimated repair costs if issues arise
Future Budget Planning: These air-filled struts are the heart of the car's comfort. Depending on the car's history, you might eventually need to budget for the replacement of a strut or the compressor unit to maintain that smooth ride quality.
Future Budget Planning: Because the CLS 63 is a heavy machine with plenty of power, the brakes work hard. If this component needs attention in the future, the estimated cost in NZ reflects the performance-grade parts required for the AMG package.
Future Budget Planning: The 6.2L V8 is a masterpiece of engineering, but it is complex. Should the top end require maintenance due to wear over time, it is wise to set aside funds for a specialist technician to perform a refresh.
