Question

Quizplus · Accepted Answer

The Diesel Particulate Filter (DPF) typically does not need to be removed and cleaned annually, nor does it require active regeneration at every oil change. DPFs are designed to regenerate automatically during normal vehicle operation, and manual intervention is only needed if the vehicle's driving conditions do not allow for automatic regeneration.
