Everything you need to now

What does NOx sensor delete involve?

It involves reprogramming your vehicle’s ECU to permanently remove NOx monitoring. This prevents any future faults or warnings related to the NOx system.

Is this service legal for road use?

No. NOx sensor delete is only legal for off-road, export, or motorsport vehicles. It is not permitted on UK public roads.

Will it remove limp mode and fault lights?

Yes. The delete removes all NOx-related errors, including reduced power (limp mode) and dashboard warnings.

Is any physical work done on the vehicle?

No. The delete is done entirely through software—no wiring, cutting, or sensor removal required.

Can the delete be reversed later?

Yes. If you need to return the vehicle to factory settings, we can fully restore the original ECU software.
