Is the 2.0 TSI / TFSI reliable?

It depends above all on the generation. The earliest units (2008-2012, without Valvelift) have more oil consumption complaints and somewhat more chain and tensioner wear; from 2012 the Valvelift design reduced oil consumption but kept carbon build-up on the intake valves as a weak point until, around 2016, supplementary indirect injection was added. The thermostat housing with the integrated water pump leaks coolant in several generations.^{[1][2][3][4][5]}

Is the M111 reliable?

The M111 is the four-cylinder petrol engine Mercedes-Benz fitted from 1992 to 2006 in the C-Class (W202 and the early years of the W203), the E-Class (W210), the CLK (C208), the SLK (R170) and the Sprinter, in naturally aspirated form and with a mechanical supercharger (Kompressor). A German used-car guide describes it as reliable when well maintained, with limited weak points: the head gasket and an oil leak into the camshaft adjuster wiring.^[6][7]
