Cost Prevention Measures To prevent this problem, before you purchase a Mercedes-Benz model with the M272 engine, check with an extended warranty company to see if they can cover the expense if the balance shaft should fail. Peak torque arrives at 5000-rpm with most of this available from 2500-rpm. The M112 E32 V6 engine replaced inline 6-cylinder series on the production line in 1997. The most powerful of the bunch was the 280-hp Alfa Romeo Giulia. Manufacturers can voluntarily recall cars for problems that do not affect these, though. It's great when some one takes the time to be so informative. The M112 engine lies at the base of M272 engine design.
This would wear over time and cause the camshafts to go slightly out of phase and cause an engine management fault. Keeping with Motorsport tradition, all joining parts of the inlet system and intercooler employ captive O-Rings rather than gaskets and sealants for consistent sealing and maximum reliability. However, Mercedes-Benz would not admit to any misconduct in the suit. Note that we now have the M276 to replace it, so the 272 is old hat! Ensure the M272 engine serial number is later than 2729. The broad power range of M271 1. Its crankshaft is hollow-cast to reduce mass and uses eight counterweights. When doing this, the M272 never sounds harsh, and will rev to beyond 6k building power all the time.
It is quite an expensive fix that , so make sure you cover your bases before you invest in one of these affected models. This minimises the production line re-tooling since this type of V6 is effectively a shortened V8. This problem occurs on engines until 2007. Check the plastic plugs of cylinder heads; perhaps they need to be replaced. The Most Common Problem with Mercedes-Benz Engines Unfortunately, it is the balance shaft gears that show up with glitches for most Mercedes-Benz E-class models with the M272 engine built during the period of 2004-2008. To achieve even firing pulses throughout the 4-stroke 720-deg cycle, a 6-cylinder engine should produce a power stroke every 120-degrees.
So, avoid the earlier engines with the balancer shaft problem and the engine appears robust and reliable. A modular balance shaft in the lower part of the block reduces inertia. The next step in the development of V6 Mercedes engines became the appeared in 2004. The 252-hp Audi A4 is the ideal engine in so many ways, except it comes up short in observed fuel economy. This is not a fix you can do yourself.
Three European luxury sport sedans and one coupe, all sporting 2. The engine operates unstably with that problem. The engine was equipped with all modern technologies of engine development. The M272 utilises a 90-deg block in common with the V8 engines. The M272 engine also has a balancer shaft inside the engine block. The new generation engine has utterly new cylinder block, which cats from aluminum alloy with cast iron sleeves.
? The engine has a timing chain and small supercharger Eaton M65 Kompressor. Mercedes-Benz engineers contend the BlueDirect 2. Good for you, but don't buy anything untill watching this video. The engine is designed in V configuration the cylinder bank's angle is 90 degrees. Later engines utilise a harder grade sprocket and do not exhibit the problem.
The cylinder block is aluminum, instead of heavy but reliable cast iron. The dimension between cylinders is the same 106 mm. A large, internal bypass valve is employed to ensure smooth throttle transitions and to keep parasitic drive losses to a minimum. The engine has variable valve timing system on both camshafts. M272 series is the new generation of V6 Mercedes engines. Its not my favorite job in the world. The diameter of the intake valve is 30.
If you sign up for notifications in My Garage, we will try to get these to do, but for various reasons some beyond our control cannot guarantee you will receive them. You can also check with the dealer, which will know which if any recalls pertain to your car. This is by far one of the models, including E25, E30, and E35. Still Learning - Thanks for the in depth write-up. This methodical process of elimination led us to one engine that does it all — smooth and quiet at startup and idle, rev-happy and ready to run and capable of 27 mpg 8.
