E350 CDI Coupe
642DE30LA.PNG Hi all,

Have a 2010 E350 CDI coupe, type C207. Questions on engine type.

The mercedes dealer is telling me the engine in the car is a 642.836
The engine number on the vehicle cert is starting with 642836 .... So all good until ...

When I enter the service menu on the dash the engine is given as: 642DE30LA (see image)

After a bit of searching bewteen 09/2009 and 09/2010 these did come with a 642DE30LA engine, so this source suggests: Viridian Performance models |

Also if I use my diagnostics and tell it it's a 642.836 engine then I can do no functional tests, like turn off injectors etc. If I tell my diarnostics its a Mercedes Sprinter, which came with a 642DE30LA engine, then I can do functional tests, no problem.

So dealer and engine number says one thing and the car display plus diagnostics suggests another.

So 642.836 or 642.DE30LA ?

Also where do Mercedes hide the engine number on the block ?

I'm having a few problems with rough idle but want to sort this first ...

Thanks for any help,

Joe

Where is the Engine Number hidden ...

On the block directly under the high pressure pump.
