That looks bad my friend, not the photo itself... but the whole story. When you say accelerate, do you mean hit the cut-off or run at high revs for a long time until you hear something in the engine and it starts to malfunction...? It sounds like a serious mechanical breakdown to me, since what's in the image doesn't even look like carbon particles.

And how should I proceed now, where should I look for the problem. previously the particulate filter was overfilled. regeneration was done via the computer, with the control unit being reset and then regeneration

I know English is not your native language, but please be more specific. Is the "computer" a scan tool? If so, please identify what scan tool you are using.

Also, what year is your car?

Ewtis

yes sorry 2013 . the computer does not report any errors, the computer is an original Mercedes

So, you are using a STAR Diagnostic System (SDS)/XENTRY to scan? Running rough (shaking) would seem to be caused by misfires and should show codes. Is your car a Diesel? Sounds like it.

Ewtis

yes, star diesel just doesn't show anything when I put my finger in the exhaust, all black

How long have you had the car? Did this problem just happen?

Ewtis

yes, I've had the car for a month and a half, I changed the air filter and the engine head gasket was done, this appeared a week ago
