![]() ![]() The system can only be reprogrammed (deleted) if the system is fully operational, remember we are NOT deleting the system just reprogramming it to stop the ECU putting the vehicle into limp mode once the DPF filter is removed. We also recommend that you submit any fault codes related to the system that you intend on “deleting”. By reprogramming the ECU to expect much wider levels of backpressure the DPF light won’t appear once the DPF is removed also it stops the ECU prompting for a DPF regeneration therefore “DELETING / BYPASS” the DPF. The term DELETE is incorrect it’s more REPROGRAMMING of the DPF system to now expect a much wider margins of DPF backpressure. Q4: What do I need to do to successfully delete the DPF system? This also shows you if anything needs to be disconnected. To answer this question you need to follow the below link to the software that we use to delete the DPF system from a ECU. Q3 – Can I delete the DPF on this vehicle? Please follow our below guide to DPF delete. ![]() Many try to remap it out then remove the filter after but this can cause issues as the car may display new fault codes after the remap once the DPF has been removed. We recommend removing the DPF internals prior to requesting the DPF delete, ideally the car should be driven for at least 20 miles to allow any DTC (fault codes). The filter MUST be removed but all sensors MUST remain plugged in, some try to fit a straight though pipe but then the sensors have nowhere to go and therefore the DPF delete wouldn’t work. The DPF system must be in a working state and ALL DPF related sensors must be working for the DPF delete to work correctly. It’s a MUST and can be dangerous if it’s not removed. Q2 – Does DPF to be removed once it’s been deleted? In 9/10 cases the EGR can be successfully deleted without any adverse effect to the DPF regeneration process. So in some cases a EGR delete could cause the DPF system to fail to regen and in turn would then block up the DPF. Some DPF systems use the EGR system to aid the rise of the exhaust gas temperatures to help perform a DPF regeneration. ![]() The DPF is a visual inspection at the MOT if it looks to be tampered with it’ll fail the MOT The filter looks like a ceramic honeycomb, make sure you ONLY remove the DPF and not the CAT (Catalytic Converter). The DPF needs to be removed from the car and the filter internals needs to be knocked out. Remove the DPF via ECU Remapping – Cheap, fast but doesn’t comply with MOT / Government regulations.Remove DPF and deep clean – Takes lots of time and needs the car to be off the road for days.Clean the DPF using the REDox DPF Cleaner – Expensive but complies with MOT / Government regulations.Replace the DPF – Expensive but complies with MOT / Government regulations.In cases when the car is driven around town in stop start style driving (In traffic) the DPF can’t perform a regen and then therefore becomes BLOCKED. Then driven on the motorway for a minimum time, distance, speed and RPM. To perform a REGEN the car must meet certin conditions such as Have a least quarter of a tank of fuel, have sufficient engine oil, have working EGR, glow plug and other components. At this point the DPF must perform a DPF regeneration to clean itself. This unfiltered soot can be breathed into the respiratory system, the DPF catches this SOOT in the DPF then after some time once the DPF becomes filled / blocked. The DPF is fitted to try and help lower emissions and to catch small particulates found in the exhaust gases made by diesel engines. Q1 – How DPF’s work and why do we have them?įirstly DPF stands for Diesel Particulate Filter. Many questions are raised on DPF Delete: How do I do it? Which we will cover below: ![]()
