Oil leakage from cam plugs, frequent breaking of the intake manifold plastic cover, timing chain problems due to balance shaft wear However, worst of all, they even ruined the glorious S-Class with the unruly M272. Mercedes-Benz had to fight off a class action lawsuit in 2010 relating to faulty components within the M272 V6 engine. As a result, permanent check engine lights and misfires are standard on M272-powered cars. Timing chain issues causing premature wear to the surrounding components occurred in as little as 100,000 miles. ![]() In the early 2000s, Mercedes-Benz was undergoing a reliability crisis, and the cheaply built M272 engine block only worsened things. Producing a maximum of 201 hp and 181 lb-ft of torque, the DOHC V6 was your typical A to B power plant, or it was supposed to be. Produced between 2004-2017 to replace the M112 V6, Mercedes unleashed the entry-level 2.5-liter M272 V6 found on base-level cars such as the C230 and E230 vehicles. Timing chain and fuel pump failure due to lack of periodic maintenanceĢ005-2011 Mercedes-Benz C-Class, 2005-2011 Mercedes-Benz E-Class Reliability Of Mercedes-Benz OM617 Engine This old Merc crossed the auction block with a whopping 782,000 miles on the clock, thanks to the OM617 housed within. A recent testament to Mercedes-Benz's reliability is the 1979 Mercedes-Benz 300TD wagon that went up for sale in recent years. Mercedes-Benz produced 2.7 million OM617 power plants over 17 years to cement the five-cylinder's stubborn reputation as one of the best diesel engines in the world. A five-cylinder engine to replace the outgoing OM616 quickly garnered a reputation for reliability, with many fleet vehicles approaching 620,000 miles as time passed. Produced between 1974-1991, Mercedes-Benz loaded their 300D with a cast iron 3.0-liter diesel engine known as the OM617. Does anyone have any experience on re-starting the motor after an injector replacement or after opening the HPFL for any other reason? Much appreciated.1977–1981 Mercedes-Benz 300D, 1977–1981 Mercedes-Benz 300CD So I am wanting to get the car started, but at the same time do not want to damage anything. The rep said sometimes 2 minutes! I said weren't they concerned about the HPFP cranking that long w/ no start. ![]() They said no, just simply crank the motor till it starts. So I went to the local BMW dealer to ask if they use diagnostic software to activate the fuel lift pump to the HPFP. Curious, I had a friend crank the car as I cracked the HPFL to the replaced injector, no fuel. As means of comparison, after replacing the FF before, the car would only need maybe 3 seconds to re-fire back up. It would crank, but I limited it to just a few seconds (less than 15) for fear of running the HPFP without bleeding out the system. ![]() Now that the engine was back together I tried to start it. The mechanical part was pretty uneventful, had the new injector installed in about 45 minutes. It had thrown a CEL and there was a discernible miss at low RPMs w/ medium load (driving uphill into the garage). I just now replaced a faulty fuel injector in my 2010 335d.
