Engine: M270
M270.910 · turbo petrol · A160 · Used in this car from 2015-2018
Strengths
Economical for such power output
No issues with service and spare parts
Watch-outs
Frequent problems with camshaft adjusters
Timing chain stretches very quickly
Not the most reliable thermostat and water pump
Known engine issues
Camshaft adjuster rattleIn engines up to 2014, camshaft adjusters quickly failed and began to rattle; later they were updated and the problem appeared much later, but did not disappear completely. The timing chain also does not have a high service life, usually replaced every 100-150 thousand km.
Impulse disc displacementIn engines of this family, the impulse disc is pressed onto the camshaft and gradually shifts with each start. A stretched chain accelerates the process. This causes starting problems up to complete failure.
Piston destructionIn 2015, engines of this series received a different firmware and became more economical, but immediately there were reports of destroyed pistons due to detonation. Also, low-quality fuel greatly reduces the life of piezo injectors of direct injection.
Listed from most frequently reported, each with its source.
Overheating due to water pump/thermostat
Often reported
Cooling system issues, especially engine overheating caused by water pump and thermostat, have been reported.
Cooling
Oil pump problems / irregular oil pressure
Often reported
The 1.5 diesel engine's lubrication system may show abnormalities related to the oil pump: pressure fluctuations or failures can cause dashboard warnings, noises, and suboptimal engine operation. If not diagnosed and repaired, these failures can lead to serious engine damage.
Engine Internal
Phase adjuster / timing chain noise and wear
Often reported
A metallic noise on cold start has been reported in W176 examples, typically a sign of phase adjuster or timing chain (tensioner) wear. The issue may appear after tens of thousands of kilometers and, if neglected, may require chain replacement.
