New MB CDI's are common-rail and electrically injected.
Maybe the definition of "electronic injection" should be clarified. To my mind any IP with electronic controls is an electronic pump. Obviously the pressure in the fuel system, any fuel system, has to be created mechanically. Some modern injectors are fired mechanically, some electronically. Even the mechanical injectors on the new TDI are "second stage" injectors. The fuel supplied to them is already at a very high pressure, AFAIK. If its got a computer control its electronic injection. So I stand by my statement: "I don't think that there is a single diesel made for the US market that does not have an electronic injection system on it" If it wasn't computer controlled it wouldn't pass US emissions.
