I mentioned this to my mechanic and he pooh-poohed it.

I googled different P0410 issues, and one was hoses. In California it won't pass with a check engine light. My mechanic said I needed to pay him $100 to run diagnostics and then whatever the repairs were. I bought a cheap OBD II reader, to make sure P0410 was my only problem (it wasn't once I had to replace my gas cap).
#SENSORES DE OXIGENO MERCEDES C230 KOMPRESSOR 2004 CODE#
I have had this code for some time now, and only got serious lately as my (California) smog check loomed. I found the shutoff valve which looks like the check valve is just right next to it about a foot away and is very accessable. My engine differs a little bit on the photo. I should not have any problems with the plugs since I replaced them new with 4 prongs early this yr. The cold start definitely is very rough, which feels like after turning the engine ON - I have to rev the gas once since it seems like the engine will not be able to start and would just die if I let it.

Although, yesterday I checked and found there is still power going through the kompressor which IMO, the kompressor is not damanged. I'm not very familiar on the schematics of the engine and will try out this method and see. The boost is totally gon from the kompressor and I guess maybe from this thread it is due to the check valve being shut which the air isn't going through the engine. Well, I'm still driving the benz since then. I just wonder how it managed to mess the MAF sensor as well. I just got the P0100 and P0410 codes a couple days ago for my 2K C230 Kompressor 150K miles I just replaced my MAF Sensor Last yr from Ebay (non orig part for $40) I guess that did not last long.
