I have no doubt I could have done it but having read all the problems others had out there, I wasn't in the mood for a challenge.
Mine had maybe 175k miles with EGR in place so it was really sooted up.
It is not cost/time effective to DIY IMHO. Take it to a dealer and qualify for your next 2 years of roadside assistance to boot!

I did the same thing with the ML320 after hearing the horror stories. Mine needed all 6 changed plus the controller because they changed the plug design which also changes the controller.
Oh and BTW the roadside assistance rules have changed. It is pretty much worthless and you may not even qualify anymore.
