How often should you do a parked regen?

Depending on your driving, active regeneration may happen as often as once a day. If you do a lot of stop and go, it can happen even more often.

How far do I need to drive to clean DPF?

To make sure that the regeneration takes place, most manufacturers suggest that every few hundred miles, the car is driven for a period of more than 15 minutes at a consistent speed in excess of 40mph. Doing this should clear the filter.

How long should a regen last?

approximately 45 minutesJust like most other operators that are using our tool for preventative maintenance, this would be the typical experience.

Can you regen a truck while driving?

How long is parked regeneration?

How much does a forced Regen cost?

The cost for a forced regeneration varies. Generally, it is between $300-$700 depending on the technician’s required diagnostic time and the length of time your DPF regeneration lasts.
