پایین بودن سطح سوخت و جلوگیری از احیا

A fuel level too low for the module to begin a particulate filter regeneration. Regeneration consumes a noticeable amount of fuel, so the module refuses to start one below a threshold rather than risk stranding the vehicle mid-cycle.

It is an inhibit rather than a fault, and a sensible one — but its consequence compounds, because a filter that cannot regenerate keeps loading. A driver who habitually runs low is preventing every regeneration, which eventually produces a filter fault that looks mechanical. Check the fuel level in the stored abort reason rather than the codes alone. The remedy is a fuller tank and a sustained run, and telling the owner that is a more useful outcome than a part.
