Reliability, problems and repair of the Mercedes M272 E30 3.0 liter engine

The middle version in the family of V-shaped sixes M272, occupies a place between the M272 E35 and 2.5-liter M272 E25, the main purpose of the model is to replace the obsolete M112 E28. The aluminum V-shaped (90° camber) cylinder block of the M 272 E30 is similar to that used in the M 272 E35, but with smaller diameter cylinders (88 mm vs. 92.6 mm in the 3.5L) and a crankshaft with a shorter piston stroke (82.1 mm vs. 86 mm).

Mercedes-Benz M272 KE30 3.0 liter engine

Cylinder heads are similar to the M272 E35: aluminum with two camshafts (DOHC) and 4 valves per cylinder, diameter of intake valves reduced to 37 mm, exhaust valves to 28 mm. Still used are continuously variable valve timing on intake and exhaust shafts, hydrocompensators, two-stage intake manifold with variable length.

The timing drive uses a double roller chain, its service life is about 150 thousand kilometers. Control system Bosch ME 9.7.

The engine was designed for Mercedes models with index 280 and 300.

Production of the M 272 E 30 engine continued until 2013, after which its place was taken by the new M 276 DE 30 engine.

Problems and disadvantages of Mercedes M272 3.0 liter engines

Diseases, faults and weak points of the M272 E30 engine are similar to those in the M272 E35, learn about them here.

Mercedes M272 engine tuning

Chip tuning. Compressor

The easiest way to slightly increase power is chip tuning + exhaust. It is enough to go to a tuning studio, remove catalytic converters, put a low resistance filter, pour sports firmware and get about 15-20 hp. Having installed sport camshafts with phase 268/268 lift 11/11 (Kleemann), we will get about 20-25 hp. It is senseless to refine further in the atmospheric version, as the car will lose considerably in convenience of moving around the city. Further ways:

  1. Buy a Mercedes with a V8 M273 engine.
  2. Buy a compressor kit from Kleemann/Lotec, etc. Such kits, due to low pressure, are installed on a standard piston and allow you to increase power to 370-380 hp. The disadvantage of this method is the high price.
