Why we do not offer deletes for road vehicles
Road vehicles must meet the emissions standards that applied to them when they were built. Removing a DPF, disabling EGR or switching off SCR/AdBlue can leave a vehicle unable to meet those standards, which can make public-road use unlawful. Government guidance states that it is an offence to use a vehicle on the road that has been modified so it no longer meets the emissions standards it was designed to meet, and a missing factory-fitted DPF is an MOT failure.
Labels such as “off-road use only” or “for competition use” on a vehicle that is in fact driven on the road do not make it compliant. If the vehicle will be used on the road, the answer is diagnosis and repair of the emissions system.
What counts as a genuine non-road application
Genuine non-road applications are those where the vehicle or machine will not be used on public roads. We ask for information about the intended use and may decline an enquiry if it cannot be verified or if the work is not appropriate. We do not publish a list of eligible vehicles, because eligibility depends on the specific circumstances.
If your vehicle is a road vehicle with an emissions fault, the services you need are DPF diagnostics, DPF cleaning, EGR diagnostics or AdBlue fault diagnostics.
What to send us before booking a non-road emissions enquiry
The quickest way to get useful advice is to send the registration and a short description by WhatsApp or through the quote form. Support and suitability vary by engine, gearbox, control unit and software version, so a registration lets us check the right information instead of guessing. Any estimate given remotely is provisional until the vehicle has been seen and the required checks are complete.
- 01Vehicle registration and approximate mileage
- 02Make, model and engine size, if known
- 03Any warning lights, messages, symptoms or fault codes
- 04Existing remaps, tuning boxes or hardware modifications
- 05How the vehicle is used — commuting, towing, short trips or heavy loads
- 06Whether the vehicle is currently in limp mode or will not start
Emissions equipment and the law
We do not offer DPF, EGR or AdBlue/SCR deletes for vehicles intended for public-road use. Removing or disabling emissions controls can make road use unlawful, and a missing factory-fitted DPF is an MOT failure. An “off-road” disclaimer does not make a road vehicle compliant. Non-road enquiries are considered only where the intended use can be verified, and are assessed individually against the applicable requirements.

Visiting the workshop for a non-road emissions enquiry
All work is carried out at our single workshop at Unit 2, Lancaster Works, Kingsbridge Road, Manchester M9 5SP. We do not run a mobile remapping service and we have no other branches, so every a non-road emissions enquiry enquiry is booked into the same Manchester workshop. Visits are by arrangement: please call or WhatsApp before travelling so we can confirm the vehicle, the time and what the visit will involve.
Access is through the black gate. Call when you arrive so we can let you in, then keep left towards the rear of the site. We are open Monday to Friday 8am–6pm and Saturday 8am–1pm, and closed on Sunday. If the vehicle is in limp mode, showing a serious warning or will not start, tell us before setting off so we can talk about whether it is sensible to drive it or whether transport should be arranged.
