Is removing a DPF a MOT failure?

The most significant area for diesel car owners is stricter rules on the permissible level of emissions of cars fitted with a DPF. If a car’s exhaust emits visible smoke of any colour, it will fail the MOT test. It’s already illegal to drive a vehicle that has had its DPF removed.

Does removing DPF increase power?

Just removing a (properly working) DPF will not give you any engine performance improvement. At best removing a blocked DPF (or drilling holes) may restore some of the original engine performance. Any performance gains are coming from the ECU remap…which is why a good quality remap is the key to success.

Can you legally remove DPF?

While it’s not illegal to remove a car’s DPF, it is illegal to drive without it if one should be fitted. The process for removing a DPF is a relatively simple one that requires cutting a hole in a vehicle’s exhaust, removing the filter and welding the resultant hole shut.

What happens when I delete DPF from my car?

Our DPF delete service removes the DPF system from the vehicle’s engine control unit. After removal, the vehicle drives like a system with DPF, without error messages and without the engine indicator light lighting up. Deactivating the DPF system is intended exclusively for use off public roads. Report any changes to the competent authorities.

How do I remove DPF functionality from ecuware?

Then upload this file to ECUWare. The DPF functionality is then removed from the file. As soon as the file is ready for download, you will receive an e-mail message containing a link to the file for download. You download the file and then load this file back into the ECU. This completes the process.

Can you use jet wash to remove DPF?

You could opt to send your DPF to one of the many DPF cleaning companies who can remove the Ash buildup from the filter using fancy machines. They use specialist chemicals and extreme pressure in order to remove the Ash, not something you can do with a jet wash.

Is there such a thing as a DPF filter?

Yes, a DPF filter itself is a simple thing. A box with a honeycomb filter/mesh which stops/traps larger diesel exhaust particulates (soot) but allows the follow of normal exhaust gasses. What isn’t so simple are the sensors and ECU management which keep this system in check.

Should I Delete my DPF?

Removing the DPF is often advised to check the opacity of the exhaust emissions which can give some indication of any potential running issues which can impact on the operation of the DPF. Issues such as leaking injectors and engines burning oil can massively reduce the life of a DPF.

Is deleting DPF legal?

Deleting your DPF is only legal for race and competition use. If your diesel is only registered for street use, you cannot delete your DPF unless you’re willing to risk not passing emissions tests.

Can DPF be removed?

However, DPF removal has both legal and social implications. The DPF filters need to be ‘regenerated’ regularly through burning the soot to gas at a very high temperature, leaving behind a residue. If not carried out properly, regeneration can lead to a build-up of soot, which can affect performance.

Does DPF delete increase mpg?

DPF stands for diesel particulate filters. The major reason behind why and how DPF delete helps increase MPG is that it gets plugged with the residue from your fuel. When this filter gets plugged, the total mileage gets disturbed. It lets less fuel to pass through and therefore, increases the waste.
