Highway driving the whole way home sitting on 100 so no idea why automatic DPF regen never happened. Anyway, looking at purchasing and OBD tool to complete my own DPF regen at home as wanting to keep the car for along time. OBD tool im looking at is: Autel MS906BT. $3000NZD. It could be faulty and still working but not correctly. By sending the incorrect data to the ECM, generating more PM / carbon, stopping the DPF regeneration process, could result in a blocked DPF. The MAP/MAF sensor is an essential part in delivering the correct fuel/ air mixture to the engine. If it fails or begins playing up, the ECM cannot As Uwe already indicated, the MAF issue needs to be resolved first. For once it may be the root cause for your troubles and second it will likely block DPF related diagnostic procedures like the reset or a regeneration. When replacing the DPF at any later date, make sure to get the proper one. Early Crafter models had DPF Generation 2 from located on the DPF. It uses in-cylinder post injections via the main 5 injectors to create the regeneration. The 2016 UR Mazda BT50 3.2L on the other hand, uses a different system, the Down Stream Injection (DSI). Funnily enough this system is commonly found on other Ford models including Kuga, Mondeo, Focus and Transit. Mercedes models 300SD and 300D with a 3.0 L turbocharged IDI engine were equipped with 5.66" diameter × 6" filters, Figure 2, fitted between the engine and the turbocharger [212]. Figure 2. Catalyzed DPF for 1985 Mercedes Benz 300D A complete DPF unit and a wall-flow substrate retrieved from a used filter (Courtesy of Per Stobbe) Engine-ECU uses this voltage for DPF regeneration control. The No. 3 exhaust gas temperature sensor (DPF temperature) is a kind of resistor, which has characteristics to reduce its resistance as the DPF temperature rises. Therefore, the sensor output voltage varies with the DPF temperature, and becomes lower as the DPF temperature rises. There is only so many times a DPF can regenerate before the compacted soot reaches a critical saturation level at which point DPF removal or replacement is imminent. Eurotune have DPF solutions starting from just $395+GST . Call us today. DPF clean, repair, remove, delete and/or replace Diesel Particulate Filter (DPF) systems. If warnings are still ignored and soot loading continues to increase then the most likely outcome will be a new DPF costing around £1000. Mainly town based driving If your own car use is mainly town-based, stop/start driving it would be wise to choose petrol rather than risk the hassle of incomplete DPF regeneration.

I would reset the DPF with an oil change. Then on your first drive, do the injectors calibration after you stop. Do that only if the DPF is not regenerating at this point. Otherwise wait to do the calibration on the next drive. Do not do the forced DPF regeneration. 2MNaLZr.
