What causes damage to a diesel particulate filter?

Damage to a diesel particulate filter (DPF) can occur due to excessive soot accumulation, which can lead to clogging and reduced performance. High temperatures, often from engine malfunctions or improper regeneration processes, can also cause the filter to crack or deform. Additionally, the use of low-quality fuel or additives can introduce contaminants that damage the DPF. Regular maintenance and proper engine tuning are essential to prevent these issues.
