Is it legal and safe to delete or remove your DPF from your truck or car? In New South Wales and Australia, it is illegal and unsafe to delete the DPF from your truck or car.
A DPF (Diesel Particulate Filter) delete is where your truck or van’s emissions system came fitted with a DPF (Diesel Particulate Filter) and you remove the DPF from your engine’s emissions systems.
Here are some of the key reasons you should not delete your DPF:
In New South Wales, and most of Australia, it is illegal to drive a vehicle without a DPF where the vehicle came with a DPF. There are large fines for individuals and businesses that are caught driving trucks or cars without DPF’s.
The EPA (NSW) states:
A person must not, without just cause, alter, replace or modify the engine or
the exhaust system or fuel system of any motor vehicle in a way that-
(a) departs from the manufacturer’s design; or
(b) increases the rate of discharge of any of the constituent parts of the
emissions or (where applicable) defeats the intended upward discharge
or dispersion of the emissions.
DPF’s where created for a reason, to reduce the number of dangerous diesel exhaust gas (soot) released into the atmosphere. Some of the fumes captured by DPF’s have been linked to cancer and severe respiratory diseases.
If your car or truck came with a DPF, it’s engine and emissions management system has been tuned with the DPF in mind. Removing the DPF can, therefore, lead to performance issues with your vehicles engine and emissions systems.
