Engine: M274
M274.920 · turbo petrol · C200 · Used in this car from 2014-2018
Strengths
Very economical for this power
No problems with service and spare parts
Watch-outs
Very demanding on fuel quality
Chain and camshaft adjusters have short life
Plagued by regular oil leaks
Known engine issues
Camshaft adjuster rattlingIn engines up to 2014, camshaft adjusters started rattling quite quickly; later the manufacturer improved the design and lifespan increased to 150-200 thousand km. Around the same mileage, the timing chain stretches and many replace them together.
Impulse disc displacementMany owners of cars with this engine family complain about starting problems, the main cause being displacement of the impulse disc relative to the camshaft axis. Usually an error from the camshaft position sensor signals this.
Piston destructionIn 2015, engines of this series were modernized and became slightly more economical, but this led to more frequent detonation with piston destruction. Also, poor fuel severely affects the direct injection piezo injectors.
Several Italian forum users report that detached or damaged intake pipes, leaks in the intake circuit, or faulty valves/sensors can cause poor power delivery and engine roughness.
Engine Bay
Timing system wear (chain/phasers)
Often reported
Premature wear occurs in the timing system (chain, gears, or phasers/variators); this can cause noise, loss of synchronization, and reduced engine performance.
Engine Internal
Direct injection (CGI) system issues
Often reported
On the 1.8L CGI direct injection version, fuel system problems such as deposits, faulty injectors, or electronic injection management are reported; these can cause rough running, power loss, and the check engine light to come on.
Fuel System
Power loss / turbo issues
Often reported
Reduced power output is reported on C200 1.8 CGI (184 hp) models: the engine may feel sluggish, throttle response may be poor, and power drops may occur, often accompanied by turbo pressure codes/warnings.
