2.0L M133 Turbo - 265kW (Pre-facelift)
Petrol
While accelerating moderately in 'Sport' mode, listen for any hesitant shifts or shuddering from the DCT gearbox, as dual-clutch units can sometimes show signs of wear during low-speed gear changes in cars of this age.
Check the infotainment screen and reverse camera functionality while the engine is running; ensure the display doesn't flicker, as electronic gremlins can occasionally arise in the C117 platform.
After a warm drive, safely park and pop the bonnet to check for any faint smells of coolant or oil near the turbo housing, which can be a common point for heat-related component fatigue.
Listen for any clicking or knocking sounds from the suspension while navigating speed bumps at low speeds, as the performance-tuned setup often places extra demand on bushings and drop links.
Usually marks the interval for a comprehensive service including spark plugs and potential transmission fluid flushing.
A common point to review the health of the high-pressure fuel pump and the secondary cooling system components.
Consider a full assessment of the suspension geometry and a deep dive into the turbo charger's plumbing and wastegate operation.
Verify the service book shows consistent oil changes using high-quality synthetic lubricants, which are vital for the high-output M133 engine.
Inspect the tyre condition across all four corners, as the 4MATIC system performs best with matching tread depths and patterns.
Ensure the cooling system is clean and clear of debris, as the intercooler and radiator setup works hard to manage the turbo's intake temperatures.
Ask the previous owner if the 'Mechatronic' unit in the gearbox has been software-updated or serviced, as this can improve shift smoothness.
Check for any signs of water ingress in the boot or footwells, which helps ensure the interior electronics remain in top shape for years to come.
Estimated repair costs if issues arise
Because these AMG models use high-performance braking components, they tend to wear faster than standard Mercedes models. You might eventually need to budget for a full set of performance rotors and pads to maintain that signature stopping power.
In cars of this age, the plastic housing components within the cooling system can become brittle from the intense heat of the M133 turbo. It is sensible to keep a buffer in your savings should these need a refresh to prevent overheating.
To keep the gear changes feeling crisp and precise, the 4MATIC system and transmission require specific fluid services. If this hasn't been completed recently, you may want to plan for this to ensure the longevity of the drivetrain.
