DPF Off Remapping Files
Deactivate Diesel Particulate Filter (DPF) Regeneration Process
We’ve gathered many DPF-deactivating files for any applicable car model. Our database is updated daily - we’ve got remapping files for even the most recent cars. We can safely deactivate your car’s DPF without any damage to the ECU.
Our DPF Off files have been appreciated by many satisfied car shop owners and tuners. Register today and become one of them!
Conditions Conductive To Filter’s Clogging
More often than not, DPF blockage is caused by another serious issue. If it starts acting up, you should always thoroughly investigate the matter.
Typical causes of DPF’s blockages are:
- Only short trips - using your car for only short drives (including “urban driving”) won’t be enough to allow the DPF to function properly, as it won’t be able to reach its working temperature. This also means that the regeneration process won’t start.
- Damaged/faulty sensors - DPFs have several sensors (both before and after the filter itself) that monitor its back pressure and temperature (both initial and final). They are quite delicate and if any of them stops working, the regeneration process may cease itself.
- Faulty/damaged EGR valve - these valves recirculate exhaust gasses to the engine before they pass through DPF. In some car models, a damaged or ineffective EGR valve lets through increased amounts of these gasses, which in turn can shorten the DPF’s lifespan.
- Damaged/defective swirl flaps - swirl flaps (similarly to EGR valves) are meant to help control the car’s emissions. Any defects/damage can affect their work and accelerate DPF’s blocking, which is a best-case scenario.
- Failed regeneration - certain conditions must be met for the regeneration process to go smoothly. If any of them isn’t met or the process is prematurely stopped, the DPF won’t function properly.
DTS - Data Trouble Codes
All the ECU DPF-related errors can be eliminated by physically removing the DPF and remapping the car’s ECU with our dedicated files. The most common of those errors are:
- P0470 Exhaust pressure sensor malfunction
- P0471 Exhaust pressure sensor range/performance
- P2002 DPF efficiency below threshold (Bank 1)
- P2003 DPF efficiency below threshold (Bank 2)
- P2031 Exhaust gas temperature sensor circuit (bank 1 sensor 2)
- P2032 Exhaust gas temperature sensor circuit low (bank 1 sensor 2)
- P2033 Exhaust gas temperature sensor circuit high (bank 1 sensor 2)
- P2034 Exhaust gas temperature sensor circuit (bank 2 sensor 2)
- P2035 Exhaust gas temperature sensor circuit low (bank 2 sensor 2)
- P2036 Exhaust gas temperature sensor circuit high (bank 2 sensor 2)
- P242F DPF restriction – Ash accumulation
- P244A DPF differential pressure too low (Bank 1)
- P244B DPF differential pressure too high (Bank 1)
- P2452 DPF pressure sensor A circuit
- P2453 DPF pressure sensor A circuit range/performance
- P2454 DPF pressure sensor A circuit low
- P2455 DPF pressure sensor A circuit high
- P2458 DPF regeneration duration
- P2459 DPF regeneration frequency
- P2463 DPF Restriction – Soot accumulation
