The MaxiCheck DPF is specially designed to carry out numerous functions on the Diesel Particulate Filter system. Based on AUTEL's latest diagnostic platform, it will perform a forced regeneration, turn off the DPF light and reset ECU after the filter has been replaced, and reset the additive light after topping up. AUTEL MaxiCheck DPF is able to perform many functions on the Diesel Particulate Filter system. It can perform a forced regeneration, turn off the DPF light and reset ECU after the filter has been replaced, and reset the additive light after topping up. Autel MaxiCheck DPF Reset Tool cover many car makes, generally speaking, they are: I pulled the line from the exhaust to the exhaust pressure sensor, bit of a task but line wasn't plugged. If the map sensor does not fix it then it's going to the dealer. Update, new MAP sensor didn't fix still getting same codes above. Force regen yields .ax temp around 200 degrees so not getting hot enought. Firstly I'm not a qualified mechanic by any stretch I'm just going by what I've read online and with basic knowledge of cars. So I've got a 2014 Mazda 6 2.2d sport grand tourer which I bought from a trader in July, worked absolutely fine up until around a month ago when it started to show the 'low oil pressure, engine damage possible, check oil level' red triangle warning light on the cluster Euro 1 to Euro 6 guide - find out your car's emissions standard; Active DPF regeneration . Active regeneration means extra fuel is injected automatically, as part of the vehicle's ECU, when a filter reaches a predetermined limit (normally about 45%) to raise the temperature of the exhaust and burn off the stored soot. Without forced regeneration, soot accumulation will reach levels above 85%. The DPF will need to be removed for manual cleaning and will sometimes need replacing. Other causes for incomplete DPF regeneration. Lack of high-speed or longer journeys is not the only cause of DPF regeneration problems. Other possible causes include: Incorrect oil. 1305 posts · Joined 2009. #20 · Jun 22, 2016. As I understand it, a 'normal' regeneration is triggered by back excessive pressure measured on the engine side of the PDF. That being the case, regeneration (if required) will be triggered by brisk acceleration to 70 MPH when the engine is fully warm. Naughty Nigel. The super fine dust of the exhaust combines with oil and creates a thick sludge in the intake manifold. This then can flow down into the DPF and cause further clogging when really it's not the DPF. I've looked at 4 different diesel Subies, 3 of which have history of recurrent DPF issues and have undergone forced regen / DPF replacement. 5MKjuHS.
