There's 3 different types under that heading, all without pictures, of course, one says:

Spark Plug Connector
for Direct Coil Ignition
As used on M 104 motors,for cylinders 2,4 and 6. Fits directly on to coil . As used on M 111 motors,for cylinders 2 and 4. Fits directly on to coil .

The other says:

Spark Plug Connector
3 per car
Optional with 000 156 75 10.

these WorldPac inventory programs that everyone uses are horrible...they're ambiguous and never tell you what you need to know.

I just got my VMI from the local dealer. I just bought the car with 69K miles. The pneumatic actuator was done at 31,709 miles, the water pump at 32,535 miles along with temp sensor element, the engine harness was replaced at 42,877 miles (goodwill!) and cylinder head gasket was done at 66,203 miles (goodwill!). The orinial owner must have have a good relationship with his dealer. The local MB dealer just told me they would replace the EGR on the recall! Hopefully they won't charge me $400 to clean out the hot inlet pipe! I better clean it out myself because the CE light is triggered and I want to clean up everything BEFORE they combine it the EGR replacement and I get a whopping $500 bill, you know how service cost can esculate at a dealership. Thank you so much Arthur. Now I have to get a speedometer cable.

Yeah, very confusing

But , that is the part I was referring to..

And they used to be $8 , too
I would call Phil at fast- lane .. I am sure he will have the correct #s..

hot inlet tube...damn!
 

Paul, now I can't wrench the tube off because there is no access so I take off the EGR valve and I can't seem to extricate it off the bolt studs. Now how do I access the hot inlet pipe? Is the entry on the underneath side of the EGR valve? Is there a small entry? As I cannot flip it over to see it, is there a small opening to insert my cable to roto-root the hot inlet pipe? Thanks, guys.

Ok, I finally got around to swapping the plug connectors and the spark plugs while I was at it...and I NOTICED that the middle ignition coil is DIFFERENT from the other two?! This doesn't seem right...I guess I have to order an ignition coil to swap out the suspect "wrong" one. I can't believe some Mecedes dealer put in the wrong part, and the spark plug is black?! Please advise guys, thanks...

All's well...
 

OK, I swapped out the resistor plug connectors and reset the codes. The engine runs well and the CE light has not come back. Thanks suginami and Arthur for your help. Now the damn Becker cassette player won't accept the theft code as I can't punch a "7" when I diconnected the neg battery cable to work on the engine! Oh well, it give me an excuse to buy a CD/MP3 player for the car. The Mnroney Label for the car listed a high performance sound system as an upgrade option.
