Is M272 direct injection?
All M272 engines have aluminum engine blocks with a 90° vee angle with silicon/aluminum lined cylinders. The aluminum DOHC cylinder heads have 4 valves per cylinder. Direct injection is used in a limited fashion on the 3.5 L V6, whereas others use conventional port fuel injection.
Are there any problems with the Mercedes M272?
The M273 E46 and M273 E55 engines are the part of this one family. The new version of the M272 V6, which name is M276 DE35, came out in 2011. 1. Oil Leaks. Check the plastic plugs of cylinder heads; perhaps they need to be replaced. 2. Intake manifold valves issue. The engine operates unstably with that problem.
Why is the throttle valve on my M272 not working?
0435 – The Electronic Analysis System For The O2 Sensor In The Engine Control Unit Is Defective 0217 – M16/6 (Throttle Valve Actuator) : The Throttle Valve Is Jamming Or Is Stiff We can program and SCN Code a replacement module via a pass through device or via the RAP kit.
What makes a Mercedes M272 engine make a puttering sound?
When the balance shaft gears start failing, you’ll probably hear a puttering sound – always a tell-tale sign of engine troubles. The specific culprit for this problem is usually a prematurely worn sprocket.
What kind of heater does a Mercedes M272 have?
P0050 – HO2S Heater Control Circuit Bank 2 Sensor 1 P064D – Internal Control Module O2 Sensor Processor Performance Bank 1 P064E – Internal Control Module O2 Sensor Processor Performance Bank 2 0228 – M16/6 (Throttle Valve Actuator) : Throttle Valve Jamming (Iced Up)
Are there any problems with the Mercedes M272 engine?
Fortunately, only the early 2004-2008 M272 engines are plagued with the balance shaft failures. Though unlikely, intake manifold problems can also cause serious issues. Thermostat failures may be the single most common problem on the M272. However, it’s a pretty inexpensive and simple repair.
Can a balance shaft fail on a M272?
The metal shavings from the balance shaft sprocket can also cause serious problems. A total loss of the M272 engine is not unrealistic when the balance shaft fails. Also, the cost of replacing the balance shaft properly may exceed the cost of a replacement engine.
What are the fault codes on the M272?
When parts begin failing on the M272, air-flow may be uneven or inadequate. This can cause check engine lights and fault codes. A few common fault codes are P2004, P2005, and P2006. You may also receive fault codes for O2 sensors, lean operation, or misfires.
What kind of V angle does Mercedes M272 have?
The M272 uses a 90° V angle like most V8 engines. However, that results in excessive vibration. Mercedes installed a balance shaft on the M272 to help combat these vibrations. The balance shaft sprocket on early engines was made with weak materials.
