Diesel Particulate Filter Restriction — Soot Accumulation

High severity

What it means

The estimated soot mass in the DPF has crossed the upper limit and the ECU could not complete a regeneration to bring it back down. Very common on cars used on short trips. Continued driving in this state risks a runaway regeneration that destroys the filter.

Is it safe to drive?

No — stop driving

This code can put the vehicle into limp or reduced-power mode. Avoid extended driving and have the vehicle diagnosed promptly.
