How do you drive to regenerate a DPF?
Warm up the engine to operating temperature, then drive it for 15 minutes at constant speed on a motorway.
Aim to keep the revs above 2000rpm for this period.
The heat generated will help clean the DPF filter and the cars Regeneration cycle will usually kick in under these circumstances..
What happens during a regen?
DPF regen happens when the trapped particulates heat up enough to combust and turn to ash. The built-up soot is thereby removed as gaseous carbon dioxide. Regeneration may happen one of three ways: passive, active, or forced.
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. Frequency depends on duty cycle and how much soot collects – as often as once a day or every other day An active regeneration could take up to one-half hour or more.
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.
Can you interrupt a regen?
Veteran Member. Yes the car will attempt another Regen next time you drive. If you interrupt too many in a row you will get a warning light (I believe it’s the DPF light) and you will have to take the car to the dealership to have them force a regen using a Vag-Com.
How long can you drive with Regen light on?
The DPF light coming on is a clear indicator that your car use and driving style needs to be reviewed, and you should avoid using the car for trips like the school run or regular journeys where the car cannot reach and maintain its normal operating temperature for at least 25 minutes.
What happens if you dont Regen?
Regeneration, or regen, of the DPF filter, is the process that burns the soot accumulation that is inside the DPF filter. If you can no longer start a regen then you will eventually get stuck in a derate which will then lead to an engine shut down.
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. Unfortunately, far too often it does not go quite as smoothly. First, as a general rule of thumb, a forced DPF regen should last approximately 45 minutes.
Can you regen a truck while driving?
The truck can regen all by itself ONLY while moving. If the driver slows or stops the truck, the regen will stop. If a regen is needed while stopped, the driver or a technician must initiate a parked regen.
How long is parked regeneration?
How long does a parked regeneration take? It takes approximately 20-60+ minutes. It will continue to regen until the soot level has reached ‘low’ or ‘0%. ‘ Some trucks will let you monitor your soot level gauge on the dashboard.
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.
