Black smoke problem on Skoda Octavia

Hello everyone, I have a problem with my Skoda Octavia. When I accelerate, black smoke comes out of the exhaust. In addition, I no longer have a FAP and have reprogrammed my car for this, and the EGR valve no longer works. Has anyone encountered this problem and could help me solve it? Thank you in advance for your help.

A Skoda Octavia is emitting black smoke upon acceleration, likely due to a rich fuel mixture. Possible causes include a faulty fuel injector, a clogged air filter, or a malfunctioning mass air flow sensor. It is suggested to first check and replace the air filter if necessary, and if the issue continues, to have the fuel injectors and mass air flow sensor inspected by a professional.

Black smoke from the exhaust usually indicates a rich fuel mixture, meaning too much fuel and not enough air. This could be due to a faulty fuel injector, a clogged air filter, or a malfunctioning mass air flow sensor. Start by checking the air filter and replace it if it's dirty. If the problem persists, you might need to have the fuel injectors and mass air flow sensor checked by a professional. Please update us on your progress. Do you have any other questions?
