P0410 Code Sc
I have an '04 C230K with the 4 cyl engine. For the past couple weeks it has thrown the P0410 code. 2 codes show: P0410 and P0410 [pending]. After reading and erasing the code, it comes back after a couple days/couple hundred miles.
I have read this thread a couple times and it looks like the engine discussed above is not the 4 cyl. I have a Haynes manual and have located the air injection exhaust gas recirculation combination valve...it looks simple enough to replace.
I am not a top mechanic but willing to give things a go if they are simple. So, rather than take it to my guy who can probably fix this in a day, can anyone let me know:
1) is the recirc combo valve the problem, and if so, is it hard to replace?
2) is it some other sensor/relay and if so, what, where and how hard to replace?
3) any other ideas.
Thanks in advance for a moment of your wisdom. Hope I can return the favor in the future.

I've gone through and replaced all the valves like on the DIY and also went further to replace the spark plugs and tried to reset the circulator valve but the issue keeps coming back. I have an 02 c230 coupe with 174xxx miles and lately it seems like it comes back almost every time after i reset the code.
any suggestions?
thanks!

I just turned 100,000 miles on my 2002 coupe and got the p0410 code about a week ago...car ran fine. Reset light and it as not returned. Ordered check valve from parts.com as insurance

Hope this helps

I did replace that part (almost every part associated with this code as well), but still cant figure out what the issue is.. and it is the 111 engine.
