Excessive soot at the DPF outlet; what action is recommended?

Explanation:
Excessive soot at the DPF outlet means the filter can no longer contain the exhaust soot effectively. A healthy DPF should deliver clean exhaust after any regenerative process. When soot is still coming out, the filter is likely saturated or damaged beyond cleaning capability, so regeneration alone won’t restore it. In this situation the DPF has reached the end of its useful life and must be replaced to restore proper filtration, backpressure control, and emission performance.
