M273 E55 CLK550 Cylinder and Coil Numbering

Guys I just did a diagnostic on my car because its check engine light was on, and it showed three codes: Coil G,Coil C,and misfire cylinder 7. How can I find out which ones are coil G and C and which cylinder is the seventh?

Know this is very late but on most V6/8 motors the odd number cylinders are on the right or driver side (USA) and even #s on left side or passenger side. So on the M273 if you are looking at the engine with the hood popped, the right side will be starting closest to you(front of motor) 1,3,5,7 and left is 2,4,6,8.

the vehicle being discussed is a direct coil on plug setup. Not sure what metal boot you are referring to being stamped with a location for wire??

Is this true? The car has an M273 E55 if I am not mistaken. I am trying to get the same answer, but all info I can find is that cylinder 1 is at the front of the passenger side?
