In 1993, the 4-cylinder Mercedes M111 E18 engine replaced the E18 engine from the M102 series.

Disadvantages of the M111 E18 engine
- Most of all, grease leaks will cause you problems, and their number grows with mileage.
- The mass air flow sensor has a modest resource; if it breaks, fuel consumption increases.
- Up to 100,000 kilometers, the water pump almost always starts to leak in the engine.
- From 100 to 200 thousand km, piston skirts often wear out or the exhaust cracks.
- After 200 – 250 thousand km, the oil pump or timing chain drive already requires attention.
