In the previous engine- it was under the engine cover and was visible when the hood was opened. I don't see it in this diagram.



Maybe...

It appears to be the silver box with the heatsinks located on the right side of the first diagram. You should remove the cover to access the ports.

I'm looking to remove the ECU from my 2013 C300 for a Kleemann tune, but I'm lost as to how to get it out of there.
It looks likes a special wrench is necessary for some of the nuts, and there are zip-tied tubes attached as well.

Has anyone successfully removed their ECU from the M276?
