Mercedes C 180 2011 BlueEFFICIENCY engine M271 E18 ML
Engine reliability and common problems:
The most notable issue with this engine is the sticking of exhaust valves due to carbon buildup. Another significant problem is the unreliable timing chain, which can stretch by 100,000 km. Early symptoms of a stretched chain include a rattling or ticking noise during a cold start, lasting up to 10 seconds. Over time, this may progress to uneven engine operation, misfires, detonation, and increased difficulty starting the engine. If left unresolved, a stretched chain and worn camshaft adjusters in M271 KE and DE engines can lead to chain slippage or breakage, causing bent valves and severe damage to the timing mechanism.Other issues include frequent oil leaks from the oil filter housing or heat exchanger and rapid clogging of the crankcase ventilation system, which can result in cracked hoses. A distinctive problem with EVO-series engines is fuel contamination in the engine oil, requiring close attention during maintenance.
Overall, this engine can last around 280,000 to 480,000 km if properly maintained, using the correct quality oil and fuel, and carrying out regular checks and maintenance.
The engine has hydraulic valve tappets (lifters), which provide quieter operation and do not require periodic adjustment, but are more complex in design and can cause serious engine damage in the event of failure.
