Jan 18, 2021. #1. New Sprinter owner here. My understanding is that DPF regeneration must occur every so often in order for the emissions system to remain healthy, and that regeneration involves a cycle of "burning off" accumulated particulate to clean the filter, though the Owner's Manual doesn't really explain what is actually going on.
Particulate Filter Regeneration Stay Warm. By default, this feature should be enabled, but may be disabled on some buses. The DPF Regeneration Stay Warm feature allows the DPF to stay warm when, during an in-motion regeneration event, the vehicle speed drops below a specified threshold. When enabled, the engine will continue to provide additional
To keep the DPF clean, use the cleaning ingredient every 3 to 6 months. To find out how often you should use an additive for the Mercedes Benz Sprinter, consult the owner's manual. If the warning light does not go away, take the car to a repair to have the DPF professionally cleaned. How To Avoid A DPF Clogging. Make sure to use high-quality fuel. In T4F engines, the diesel particulate filter (DPF) traps soot from engine exhaust gases. This filter must be periodically cleaned through regeneration to maintain emissions reduction performance and fuel efficiency. How often DPF regeneration must happen depends on several factors. What Is DPF Regeneration? DPF regeneration refers to the procedure of cleaning and emptying the diesel particulate filter of soot that is created by the process of combustion. Burning off the soot particles requires heating the diesel particulate filter to a very high temperature.

Yeap, the VW DPF's rely on temps being raised by normal driving - they are passive. They dont initiate a 'regen' as ours do and raise the temperture via the ecu. I mate had a leon and he often had to take it for a 20 min mway drive to clear the DPF warning light. Burning that much fuel kinda defeats the point of owning a diesel.
