The Diesel Particulate Filter in your vehicle is designed to reduce air pollution from exhaust fumes. Unfortunately, there are several issues that can arise from it when it becomes blocked. If this does happen, there a few options available to you. One of the most effective is what is referred to as a DPF delete or removal as it is otherwise known. Please note that DPF Removal is for off-road use only. If your DPF is seen to have been removed, your vehicle will fail an MOT.

An EGR delete kit is an aftermarket performance part that removes the EGR valve and prevents exhaust from being redirected back to the engine. Ultimately, this allows your vehicle to function as if it never had an EGR valve. ... As mentioned above, EGR valves limit efficiency and rob engines of their performance.

Major Mechanical Failure:

Some vehicles, predominantly early BMWs, are fitted with metal flaps which are prone to failure. The metal screws holding the flap to the spindle become loose, entering the combustion chamber and causing catastrophic engine damage.

Leaking Manifolds:

Over time the seals surrounding the flap spindle break down and cause pressurized air from the inlet manifold to leak to the atmosphere. Loss in boost pressure will cause a vehicle to run rich, and can damage other components

When decatting a petrol vehicle, it is likely that an engine management light will be illuminated, and a fault code for cat efficiency will be stored inside the ECU memory (P0420). By careful recalibration of the engine ECU data we can disable the function of the second lambda sensor.

The second lambda sensor is used for monitoring the efficiency of the catalytic converter. Disabling the second lambda sensor will allow a decat pipe to be fitted for off road use only.

The AdBlue and SCR system is a relatively complex creation, with an array of electronic sensors, modules and pumps. These systems can fail and can be expensive to maintain. A vehicle which is used on a regular basis will consume a large amount of AdBlue, and its tank will need to be refilled on a regular basis.

Our AdBlue delete service will electronically disable your cars’ AdBlue system, along with removing the associated dashboard lights and warning messages.

Most notable issue is the sound of very new Petrol cars fitted with a PPF / OPF or GPF as the sound is very very muted and as such high performance cars do not sound like the version before them, We have research that reveals recently that this is a big  issue for customers who are buying cars for the noise and getting none at all.

If regeneration doesn’t function properly it leads to a build-up of soot affecting performance and fuel economy.  Left unattended this will result in a blocked PPF.
