"Is the E Serisi E220d reliable, and what should you check?"
When buying a used Mercedes-Benz E-Class E220d 2016 (213/238), the most frequently mentioned issue is: EGR valve and carbon deposits. Additionally, faulty piezo injectors are also commonly reported.
Engine: OM651
OM651.911 · diesel · E220d · Used in this car from 2015-2017
Strengths
Decent lifespan with proper maintenance
Modest fuel consumption for such power
Watch-outs
Finicky Delphi fuel system
Frequent bearing shell rotation
Low timing chain tensioner lifespan
Known engine issues
Fuel systemUntil 2011, main versions used Delphi fuel system with piezo injectors prone to leaks, often causing hydraulic lock and piston burn-through. A recall was even issued to replace them with simpler electromagnetic ones. Engine modifications with Bosch fuel system have no reliability issues.
Bearing shell rotationMany owners of vehicles with this diesel have encountered bearing shell rotation. The cause is dilution of overheated oil due to clogged heat exchanger or oil pressure drop from variable displacement oil pump failure. The engine also lacks a standard oil pressure sensor, but one can be installed.
Timing chain hydraulic tensionerThe combined timing drive consists of a roller chain and several gears. The chain can last up to 300,000 km, but its hydraulic tensioner often fails much earlier, and replacing it is quite labor-intensive and expensive.
Listed from most frequently reported, each with its source.
EGR valve and carbon deposits
Often reported
In diesel engines used for short trips, soot and carbon deposits tend to form in the EGR valve and exhaust gas recirculation channels. This can cause rough running, warning lights, performance loss, and sometimes valve sticking.
Exhaust Emissions
Faulty piezo injectors
Often reported
Early series of the OM651 2.1L diesel engine (170 HP version) may have faulty piezo injectors from a third-party supplier. This causes misfiring, warning lights, noticeable power loss, and limp mode.
Fuel System
Boost hose / intercooler hose tear or leak
Often reported
Users report tearing or separation of boost/intercooler hoses, causing sudden pressure loss, power loss, and limp mode. A hose tear can lead to chain reactions.
