How does DPF regeneration work? DPF regen is achieved by burning the particulates off the filter at high temperatures, leaving a small amount of residue behind. However, there are two types of regeneration: active and passive. Active regeneration takes place when the electronic control unit senses that the filter has reached its set limit.
An open-end spanner will not work without causing a mar to the sleeve nut. Before installing the new sensor spraying a can of DPF Cleaner into the open hole (the one on the rear) is an excellent move to help the dpf break free. The 1st dpf regen after the sensor change now has to be forced with a tester.
A regeneration strategy may be added to address soot accumulation during challenging, low temperature drive cycles. The typical maximum soot load in the GPF is 1.5-2 g/L [3627]. In contrast, light-duty diesels rely predominantly on active DPF regeneration, with the typical maximum soot load of 5-10 g/L. Ash Accumulation
Regeneration in the "new and improved" trucks can take from 25 minutes to 50 minutes, so plan accordingly. All that extreme heat from the burn-outs tore a hole in my exhaust pipe not to mention extra heat causing damage to engine components like starters, turbos, wiring to the computers which can totally mess up your day if you have more than 7
#1 · Apr 26, 2021 Hi, my 2007 X3 3.0d has recently started losing power and I presume it to be a dpf issue as the car has only done very short distances over the last 18 months. Is there a way of kick start the regeneration process without taking it to a bmw dealer? Is there a cheapish diagnostic unit which can fault find and initiate this? thanks

Benefit from additional features such as battery registration, service reset, OBD diagnostics and used car check.
The Lindemann Diesel Boost, for example, is a perfect cleaning and protection additive for the DPF, but also for other parts such as the fuel system, the turbo and the EGR valve. This product increases the cetane number, which results in a more optimal combustion. The result is considerably less soot formation.
When the DPF filter reaches about 45% blockage the filter will begin “active regeneration” this means that the EGR (Exhaust gas Recirculation) valve is closed, the boost pressure from the turbo is increased slightly along with a slightly higher idle RPM. Diesel is then injected into the cylinders just after combustion so that it enters the
When your vehicles dpf becomes so blocked that Active or Passive regeneration is determined by the pressure differential readings that the level is to high to attempt regeneration the ecu will displays DPF warning lights and it will go in to ‘limp mode and it is essential that the vehicle is brought to us. Continued driving will only increase
1. As far as I understand, the following requirements are must in order to be able to regenerate the DPF: - Fault codes 480A and 481A have the status "currently not present". - Engine temperature >75° C (normal operating temperature). - Exhaust-gas temperature upstream of the diesel particulate filter>240° C.
