W140 Diesel OM603 Startup after Diesel Purge; 1993 Mercedes 300SD

[@scottdavis681]

Is this the same engine in a 1991 300D?

[@docthediesel7781]

Similar. But not the same. The 300D of the early 90s had a 2.5-liter inline five-cylinder engine in the U.S. The engine here in this 300SD is a 3.5 liter inline six. While I’ve never owned the 2.5, I understand it’s essentially the same design, but with a cylinder chopped off. 🙂

@@docthediesel7781 do you know what OM motor the 2.5 is? I keep finding different answers on Google. Trying to get a more reliable answer. Thanks
