There are 2 main types of regen:
passive- this happens naturally whenever the exhaust gets hot enough for the reaction to happen.
Active- this happens whenever passive can’t keep the soot regen’d out of the dpf. The computer sees the soot load get to high so it will then take control, elevate the exhaust temperature(by adding fuel late in the combustion cycle so it passes into the exhaust) and cause the regeneration reaction to happen.
Neither is bad under normal conditions however excessive active regens can cause fuel dilution of your oil.
Heat in the exhaust is your friend, it keeps the soot load down. Long idle periods and short trip are very bad on modern diesels.
