Removing a Blocked Diesel Particulate Filter (DPF)
Removing Common Rail Diesel DPFs can be a labour intensive job as some particulate filters are part of the catalyst and therefore part of the exhaust manifold or front pipe assembly. These are often fitted as close to the engine as possible to help maintain a high temperature and to assist fast warm up. V6 and V8 engined vehicles may have two DPFs and are often even more difficult to work on due to obstructions like steering racks, sub frames and turbochargers etc., restricting access to exhaust manifold nuts or bolts. Older vehicles can present even more problems due to corrosion or seizure, in some extreme cases making it necessary for the garage to use oxy-acetylene burning equipment to remove the DPF.
Professional DPF+EGR REMOVER 3.0 Lambda Hotstart Flap,O2, DTC 2 Software Full 2017.5 version, you can use the current binary drives to start the ECUs: FGTECH Galletto, KESS V2, KTAG Master, MPPS, CMD, Byteshoter Master and all binary readers / writers, 100% files working with these 3 programs. When you remove DPF / EGR the program delete all diagnostic trouble codes associated to DPF / EGR automatically. PSA removal software is developed specially for Peugeot and Citroen. VAG removal software – for VW, Audi, Seat and Skoda. It helps to delete DTC, DPF and EGR on BOSCH ECU. The essential software modification required with a DPF removal involves: Accessing the map stored on the car's main engine ECU via OBD or direct bench connection. One of our software engineers will read the original map and save a copy. The map is modified in house to adjust the software for the absent DPF.
After removing the DPF it will be necessary to either fabricate or purchase a replacement by-pass pipe ensuring that any exhaust pressure and temperature sensor take-off points are retained.
Eyeing-up the job – Refitting
Where possible, CRD Performance will remove the DPF assembly, empty its contents and seam weld it back together so that it still appears fully intact.
With the DPF now removed the engine management system still monitors its DPF pressure and temperature sensors to check they are present and working.

Without this, the ECU will detect an error, switch on the engine management light and enter ‘limp’ mode, rendering the vehicle almost undriveable.
Software Upgrade (aka DPF Deletion)
If the Diesel Particulate Filter is physically removed from the exhaust system and the ECU not remapped to accept the changes, then sooner or later the engine management system will go into ‘limp’ mode, or LOS (Limited Operating Strategy). When in limp mode the vehicle may have restricted power and, if fitted with an automatic transmission, it may even lock into top gear to limit acceleration.
While monitoring ‘pre’, and on some vehicles ‘post’, DPF differential pressures, the vehicles’ management system monitors the current state of the DPFs and detects if one or more are present. Software DPF removal involves reprogramming the vehicle’s ECU to ignore any abnormally high or low readings from either the pre or post DPF differential pressure sensors. As previously mentioned, it is still necessary for all DPF pressure sensors to be present and working. Software changes can only be made to open up pressure monitoring parameters, preventing regeneration, not to ignore the sensors altogether.
Software Power Upgrades
Some customers, while having their ECUs re-programmed to delete the DPF, take the opportunity to have their engine re-mapped for additional power, better driveability and better fuel economy. CRD Performance use several engine remapping companies for this purpose, who offer a discount if both programmes are carried out at the same time at our workshop in Bolton.
On some vehicles, software DPF deletion is not possible; this is especially true for some Japanese and Asian vehicles. CRD Performance now have available a full range of emulators which are programmed specifically for each vehicle make and model. Installing these does not involve interfering with the vehicle’s ECU since the emulator is instead wired into several of the engine sensors. These units work by fooling the cars ECU into believing that the DPF is still present and maintained in a clean condition, therefore not requiring any regenerating, even though it has in fact been removed.
Beware of cheap DPF Removals
We frequently have vehicles brought to us in Bolton to correct a previous attempt to remove a DPF that has gone horribly wrong. Often the vehicles are in an undriveable condition, stuck in ‘limp’ mode, with the engine management light on, yet no fault codes present.
Be very aware of cheap quotes – you have been warned! “Cheap today, dear tomorrow”.

Quick and Reliable
DPF off service is a fully automatic online service to work with the ECU of vehicle. Service is available 24 hours a day. We have gathered the best practices on how to disable DPF, EGR, adBlue and etc. The service works automatically. But the result is the same as if we did this work by hand. We developed unique architecture that uses a lot of checks to reducing of the errors. The file will be processed only when all the checks are completed successfully.
You pay for one action in the task only. While processing the file, you can perform several actions with a file, for example to disable at the same time adBlue, DPF and EGR. The fee is charged only for one action. This is really beneficial because everything else you get for free. Also we offer special conditions and discounts to many of our customers. Write to us, tell us about yourself and get a significant discount on all our services.
