- EGR off

- DPF off
- EGR off
- The EGR (Exhaust Gas Recirculation valve) is a valve which recirculates the exhaust gas back to the engine cylinders to reduce the NOx emissions. The EGR valve can cause pollution in the engine block and will therefore sometimes be closed and shut down software-wise.
- DTC removal
- DTC's, also known as Diagnostic Trouble Codes, are electronic messages in cases of problems with the engine or transmission. They can be switched off when the causes are found and solved.
- DPF off
- The DPF, also known as Diesel Particulate Filter, is a filter which filters soot particles and particle matter. It's developed to make diesel vehicles less harmful for the environment. A DPF is an expensive part and can generate diagnostic trouble codes and cost a lot of extra fuel. The DPF can be removed or switched off in the engine management system.
