I get soot as well, but I'm not tuned. I think it's a common thing on c32's, but I could be wrong.

I had a similar issue with my check engine light, but it was for my secondary cats. Apparently my O2 sensor after the cats were going bad. The way they could tell was by checking the voltage of the O2 sensors and they would not respond at all some times. Check both your cats and if it's not your cats, then more than likely it's your O2 sensors.

ecu will overcompensate and push more fuel if possible, but with no exhaust mods you should not get that error...

soot is indeed rich.....but I worry that it is caused by a deeper issue.
When I was stock I removed the charcoals and the same code got on. Put them back on and light never came back. Now I have the tune same code wtf?

all the more reason to be worried about a hardware issue. Could be simple, but DEFINATELY not something to ignore.

I have the obd2 reader and eraser. I just erase it but it comes back after few hundred miles. Talked to my good MB mechanic he is going to hook it up to the laptop. Hopefully pinpoint the problem.

I hate to sound like a %# here man, but please do not ignore that error. It could be something simple (fingers crossed) or it could be something that causes you to lose the engine.

If he has MB star your on the right path, let us know what he finds out, and if you need help let me know.



Steveo post up what you have when you get it scanned...

Mine stuck, thew the cell and then got "unstuck" and cell went off and didnt code.

The shop knew the purge valve was a common problem on the 09 and changed it.
