good day everyone please help after stepping on the gas other black smoke from the exhaust and the car shakes on the computer it does not show any error Thank you all in advance for the answers

 

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?

 

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.

 

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?

 

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

 

I'm not familiar with Diesels. But black sooty smoke in an indication of running rich or bad fuel.

Googler "black soot diesel engine".

 

That car has a damaged or uninstalled FAP.Did you do a cylinder head gasket? What did the engine look like? Did you have the injectors checked? Did you code them properly afterwards?

 

I'm going to the service center tomorrow, they will remove the DPF filter and look. The computer shows no error, the engine is dry, there is nothing leaking anywhere
