M274 engine. C200 vs C300
Hello guys! This is my first thread on this forum so I'm hoping to get some good answers to my question.
I want to buy a C200 Coupe 2016 with the 2 litre petrol engine M274 around 100k km on clock, 184 HP. It is made in Germany.
I have read a lot about this engine online and noticed many people having this engine fail even with correct maintenance and early mileage. The thing is I only saw people having this nightmare with a C300 or E300 or a car that has 300 in their model name. Why this? Are the pistons better on the C200 than on C300? Am I safe to buy this car without the constant fear of it failing? Are there reports of C200 M274 engine failure?
Guys, thanks in advance for all your answers.

I think (not entirely sure though) it is the M274 s that was for North America were suffering this issue. German markets ones especially the German built ones seems to be immune to this issue, forum member Keith66 has a German built one and same goes with forum member Andy74 has been flawless in their experience.

The C200 uses the 135kW M274 version. C300 in North America uses the 180kW M274 version. Torque is different between the two variants which is easily tunable by MB.
Lower power and torque for the C200 version means less combustion pressure, therefore everything in the engine has lower stress. Theoretically this could mean longer engine life or less likely for serious failures.

Anyone with EPC (MB parts catalog) can look up piston part numbers between power levels of M274 engines. The fundamental reason to have a range of power/features is to leverage the investment in common parts. My expectation is that all 2.0L M274 variants use the same pistons. This is where the problem likely likes. If the 180kW engine uses the same piston as lower power variants, torque produced by the 180kW variant creates higher stress on the piston.
