DPF, EGR, AdBlue and OPF Off (non-road use)
DPF, EGR, AdBlue and OPF Off – emission software for non-road vehicles
DPF/FAP, EGR, AdBlue/SCR and OPF/GPF delete software from the control unit for motorsport, off-road and export vehicles. Reviewed individually.
Software that switches off emission-related functions (DPF Off, EGR Off, AdBlue Off, OPF Off) is prepared only for vehicles that are not operated on public roads, for example motorsport, off-road machines or vehicles outside EU type approval. Every request is submitted with the declared vehicle use and country of use and is reviewed before acceptance. For a road vehicle with an emission system fault, the lawful route is a repair or a return to the original software; see File Review and Original Files.
Requests are submitted from a DR-files account. If you are not signed in, you will be asked to sign in or register first. The selected service is kept.
