Today I came across my car showing the message “DPF regeneration in progress”
when it pops up the engine isn’t idle and engine noise increases.
What causes it? What you should do when the message pops up?

DPF is a filter that removes soot particles from the exhaust, when you do a lot of slow driving it clogs up and the engine runs a special regeneration program that revs the engine and add extra fuel to heat the filter and burn off the soot. You don’t need to do anything
