The vehicle will then illuminate its engine management and emission warning lights to warn the driver of a problem.Ĭonnecting diagnostic equipment to the vehicle will retrieve diagnostic trouble codes, which are used to locate the area of the engine requiring investigation.ĭepending on driving style, regeneration takes places every 300 to 500 miles, when the DPF is filled with soot to a level of about 45-50% of its capacity.Ī pressure sensor referred to as a Diesel Pressure Feedback (DPFE) sensor is used to monitor the amount of PM (soot) in the DPF by measuring the level of pressure in the exhaust system. Regeneration is a process to clear the soot that has been collected inside the DPF.įailure to regenerate will result in the soot building up inside the DPF, which leads to a lack of power problems due to the high back pressure in the exhaust. In order to operate fully, the DPF needs to regenerate. The diesel particulate filter WILL, if left, block up. In order to achieve this reduced level of PM (soot), diesel particulate filters are now fitted to diesel engine vehicles.

Vehicle manufacturers are required to reduce diesel engine emissions in accordance with the Euro Emission standards. The DPF allows exhaust gases (with Particulate Material) to enter the DPF and the soot is trapped inside the filter, allowing cleaner exhaust gases to exit into the atmosphere which reduces exhaust emissions.

The diesel particulate filter is designed to trap and store Particulate Material (soot) that is produced by the diesel engine during normal driving. Once determined, it may be possible to configure TorquePro to send such a command through non-crappy Bluetooth OBD dongles.This month’s Technical Focus article takes a look at some hints and tips to consider when dealing with diesel particulate filters. I think - that if someone had an MUT3 or whatever they use to start the DPF burn process AND a Y-splitter for a OBD2 port then MAYBE a non-crappy Bluetooth OBD mixed together with my software could help us discover the what the 'do a DPF burn now!' command might be. It's fine with TorquePro - but it does not handle the API correctly and I can't get reliable data from it. I determined my $1 ELM clone was not up to the task.

I was trying to learn about what commands are in the CAN bus. It can eavesdrop and write out the content of an 'AF MA' command. I wrote a UWP app for Win10 that would work with a crappy ELM unit I have.
