Alright, I've narrowed this problem down to the EGR itself, or blockage of the EGR tube to intake -- I'm betting on the blocked tube.

However, I try to follow the EGR tube around the head and over to intake side but I can't see where it attaches back into the intake. I've seen it in other 104 pictures but maybe my 104.941 C280 is different?

Could someone please give me an approximate location of where I should be looking?

Wow, I sure do miss working on my 103 -- not enough room to do anything on this car!

Also, I'm perplexed as to why the check engine light hasn't tripped. Will it only light if the EGR valve itself gets stuck open, or should it light up also with a clogged tube.

Thanks again all!
