The error code P2458 - Diesel Particulate Filter, Regeneration Time Exceeded - is triggered when the diesel particulate filter cannot regenerate and the necessary regeneration process exceeds a certain duration.

Possible causes:
- Diesel particulate filter is too full (ash).
- Incorrect readings from the exhaust temperature sensors, which should be checked for plausibility.
- A malfunction in the engine that prevents proper exhaust gas temperature and sufficient airflow for regeneration.
