↻
Regeneration Support
Where suitable, identify why regeneration is not completing and advise on the next repair or cleaning step.
ECU
Software Adaptation After Repair
Supported resets, adaptations and software-related work following a lawful mechanical or emissions-system repair.
OFF
Off-Road / Competition ECU Solutions
For dedicated vehicles that are not used on UK public roads, DPF, EGR, AdBlue/SCR and related emissions software functions can be disabled where technically supported and lawful for the vehicle’s intended use.
Road-going vehicles
Fix the fault without pretending the emissions system does not exist.
For vehicles used on public roads, manufacturer-fitted emissions control equipment must remain present and functional. Our road-vehicle service focuses on diagnosis, cleaning/regeneration support, sensor and component fault finding, repair support, and appropriate software resets or adaptations after repair.
We do not describe emissions-control deletion as “MOT safe” or road legal. If your DPF, EGR or AdBlue system is causing problems, send the registration, fault codes and symptoms and we will advise on a compliant route forward.

Off-road / competition use only
Dedicated off-road vehicle? We can help.
For dedicated off-road, motorsport or competition vehicles that will not be used on UK public roads, we can offer software solutions including DPF OFF, EGR OFF and AdBlue/SCR OFF where technically supported.
This service is not supplied as an MOT workaround and is not intended for road-going vehicles. The vehicle owner/operator is responsible for ensuring the intended use and any modification complies with the rules that apply to that vehicle and activity.
