The EGR (Exhaust Gas Recirculation valve) is a valve that returns exhaust gas to the engines cylinders to reduce NOx emissions. The EGR valve can cause contamination in the engine block and will therefore sometimes be closed and disabled by software. Switching off the EGR valve is prohibited in the Netherlands.

DPF stands for Diesel Particulate Filter and it filters soot particles and dust particles. The filter is designed to make diesel vehicles less harmful to the environment. A DPF is an expensive component and can generate diagnostic error codes and cost a lot of extra fuel. A DPF can be removed or disabled.

DTCs are also known as Diagnostic Trouble Codes. They are electronic messages in case of problems with the engine or transmission. They can be turned off when the causes are found and resolved.

FLAPS are small valves that vary the length/volume in the intake manifold to get a finer clutch and more efficiency. It is possible to remove or disable the flaps in the engine management system. Sometimes the valves break and when they do, there is a bigger chance of damaging the engine.

Many cars have a Vmax, in other words: a speed limiter. It is possible to remove the Vmax from the car in order to experience the full potential of the car.

AdBlue is a system that converts harmful NOx in diesel fuel exhaust into harmless nitrogen and water vapor. This significantly reduces emissions of nitrogen oxides (NOx). Adblue can also be disabled in the engine management system.
