- Skipping ABC fluid and filter services contaminates the hydraulic system and turns a $500 flush into pump, valve-block, and strut replacements costing five figures across the car.
- Neglecting MCT transmission fluid degrades the wet startup clutch, producing shudder that ultimately requires clutch-pack or transmission work costing thousands.
- Stretched oil intervals on the biturbo M157 coke the turbo oil feed lines and accelerate bearing wear — turbo replacement on this engine is a multi-thousand-dollar job.
- Old brake fluid and worn AMG pads on a 4,500-lb, 500-plus-hp coupe compromise the one system that has to work every time.
- Ignoring seeping valve cover gaskets lets oil reach hot exhaust and turbo components, adding fire risk and killing ignition coils sitting in oil-filled plug wells.
- Running collapsed engine mounts hammers the exhaust, driveline, and transmission mounts and makes every other vibration diagnosis harder.
Common issues at higher mileage
- 60,000+ mi / age-related
- ABC suspension leaks — weeping struts, tired pumps, and failing valve blocks; repairs commonly run $2,000–$5,000+ per corner and multiple corners often follow each other
- 60,000–100,000 mi
- M157 valve cover gasket and turbo oil line seepage as gaskets age; oil smell after hard driving is the early symptom
- Any mileage on neglected fluid
- MCT transmission low-speed shudder and harsh engagement when the wet-clutch fluid service has been skipped
- 70,000+ mi
- Collapsed fluid-filled engine mounts causing idle vibration and drivetrain clunk
- Age-related
- C216 electronics gremlins — soft-close trunk mechanisms, keyless-go, and control modules develop faults on aging examples
