How long does it take to Regen a diesel engine?

Can you regen while driving?
When everything is working as it should, regeneration occurs automatically while the vehicle is in motion, unnoticeable to the driver. Using the heat of the exhaust itself, soot is burned off the DPF often as quickly as it accumulates. This is known as passive regeneration.
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 do you know when parked regen is done?
Another common warning indicator is the diesel particulate filter (DPF) light. The DFF light comes on when the system needs to regenerate. When it’s flashing, the regen must be done while parked. A solid DPF light means you can do a parked regen or a passive one.
How many times can you regen a DPF?
Active regeneration will be initiated every 300 miles or so depending on how you use your car and will take 5 to 10 minutes to complete. But it’s a problem if your journey’s too short and the regeneration doesn’t finish.

How long should a DPF filter last?
