DPF Solutions

Does your diesel vehicle have a large lack of power and extremely high fuel consumption? This could mean the diesel particulate filter (DPF) has potentially clogged or failed. It only has a limited capacity to store particulates. After a certain amount of time the soot particles must be burned in a regeneration process the vehicle should perform automatically to turn the soot into CO2 and ashes but this can fail for many reasons.

We can perform a DPF clean with the DPF in situ. This can be done quickly, simply and significantly more economically than replacing it. The other solution is to have the DPF emptied and gutted out with an accompanying engine management solution installed to prevent any more problems.

EGR Removal

EGR Valves are Exhaust Gas Recirculation devices and are used for emissions control, mostly used in diesel-powered vehicles. Over time these can clog and reduce your cars performance and economy.

There are two ways of removing the EGR System from the vehicle. The first way is by using one of our EGR blanking plates which we can custom fabricate for your vehicle in-house and the second is by removing the EGR system from your vehicle's ECU.

The EGR Valve should NOT be removed on vehicles that still have the DPF Filter in place, doing so may block the DPF as the EGR Valve operation is a prerequisite for DPF Regeneration.


In the UK it is illegal to remove any of the original emissions equipment fitted to a vehicle from the factory. Vehicles with the DPF removed will fail an MOT. It is the customers responsibility to ensure they comply with rules and laws relating to their home country. Fast Road Conversions accepts no responsibility for the use of this part on the public highway where removal of emission controls is prohibited.
