Order of inspection
P2458 Diesel Particulate Filter Regeneration Duration Medium
The P2458 code means the diesel particulate filter regeneration lasted longer than expected or did not finish. It usually happens when regenerations keep getting interrupted. Drive with caution and head to a shop, because a filter that cannot regenerate ends up in limp mode.
