High revs, loss of power or strange noises from under the hood? These could be typical problems of the Mercedes-Benz M270 engine. At MB Master in Kyiv they will carry out precise diagnostics, replace the timing chain, repair phase regulators and other work so that your Mercedes works perfectly again.
What are the most common Mercedes M270 engine malfunctions and how do they manifest themselves?
1. Rotating the timing belt lancet
2. EGR valve and throttle valve contamination
3. EGR valve and throttle valve contamination
4. Overheating and destruction of the piston group
Maintenance Recommendations
1 Engine oil (5W-30 or 5W-40) – change every 10–12 thousand km.
2 Oil filter – replaced together with the oil.
3 Air filter – replacement every 15 thousand km.
4 Spark plugs – replacement every 60 thousand km.
5 Coolant – replacement every 2 years or 30 thousand km.
6 Timing chain (Timing chain) – recommended replacement every 100–150 thousand km, despite the declared unlimited service life.
The 1.6- and 2.0-liter M270 gasoline engines were produced from 2011 to 2019. They were installed on Mercedes models with a transverse engine layout, including the A-Class, B-Class, CLA, and GLA. The longitudinal version has the M274 index.
1. Rapid wear of phase regulators
Especially typical for engines before 2014.
Resolved by replacing the phase regulator kit and timing chain.
2. Timing chain stretching
Needs replacement after 100–150 thousand km.
Ignoring leads to valve jumping and bending.
3.Displacement of the pulse disk
Affects the start and stability of the internal combustion engine.
4. Detonation and destruction of pistons
Often after reflashing in 2015.
Using gasoline below AI-95 significantly increases the risks.
5. Overheating
Unreliable thermostat and pump.
Overheating easily leads to cylinder head failure.
6. Leaks and other failures
Crankcase ventilation, heat exchanger gasket, seals, turbine actuator, adsorber, injectors.
