What services do you offer?

Our services include performance and economy remaps, AdBlue and DPF diagnostics and solutions, NOx fault investigation, bricked ECU recovery, immo off, ECU cloning and instrument cluster repairs.

Where are you based and what areas do you cover?

We are based in Durham and cover a wide area of the North East of England with both mobile and workshop ECU services. Regular call‑out areas include most Durham (DH), Sunderland (SR), Newcastle & Tyneside (NE), Darlington & County Durham (DL) and Teesside (TS) postcodes. If you are outside our standard mobile coverage, you can usually bring the car to our Durham workshop for ECU remapping, diagnostics or AdBlue/DPF work.

What is ECU remapping?

ECU remapping is the process of safely recalibrating your vehicle’s engine control unit (ECU) software to optimise performance, drivability and efficiency. We use original software and professional tools to tailor maps for your specific vehicle. Learn more about our ECU remapping services in Durham.

Will an ECU remap damage my engine?

When carried out correctly with proper diagnostics and safe tuning limits, ECU remapping will not damage your engine. We always start with a thorough diagnostic check, use manufacturer‑correct data and keep reliability as the top priority. You can find out more about how we work on our dedicated page for ECU remapping in Durham.

Do you offer brand‑specific remapping?

Yes. We have extensive experience with Audi, BMW, Citroen, Ford, Peugeot, VW and many other manufacturers. We also handle model‑specific issues such as Fiat 500 instrument cluster and dashboard faults. For many of these vehicles we offer tailored ECU remapping services and diagnostics.

Can you fix AdBlue and NOx system faults?

Yes. We diagnose and resolve AdBlue, NOx and SCR system faults, including warning lights, countdowns and system failures. We can advise on the safest, most reliable and legal options for your vehicle and usage. You can read more about our AdBlue and NOx fault diagnostics in Durham and the North East.

What about DPF problems?

We provide professional DPF diagnostics, cleaning and repair solutions for vehicles with blocked or failing diesel particulate filters. Where appropriate we combine DPF work with ECU software corrections for a long‑term fix. For more details about this service see our page on DPF cleaning in Durham and the North East.

Do you offer mobile ECU remapping?

Yes. Our mobile ECU remapping service covers Durham and the North East. We come to you with professional tools and equipment, carrying out diagnostics, reading and writing ECU data on site wherever possible.

Can you repair or clone a damaged ECU?

We specialise in ECU cloning, immo data transfer and plug‑and‑play donor ECUs. If your original ECU is faulty, corrupt or bricked, we can often recover or transfer data so the replacement unit will work like the original. You can learn more about our ECU repair and diagnostics services, and our dedicated bricked ECU recovery support across the North East.

My ECU is bricked – can you help?

Yes. We offer expert bricked ECU recovery services. Depending on the unit, we can often recover it via boot‑mode or bench programming and restore original software so the vehicle can start again. For more detail, visit our page on bricked ECU recovery.

What is “immo off” and when is it used?

Immo off is the process of disabling or correcting immobiliser data within the ECU so that a compatible ECU can run the vehicle. It is typically used in controlled situations such as donor ECU fitting or where immobiliser components have failed. We cover this work as part of our wider ECU repair and diagnostics services.

Do you work on “locked” ECUs?

We have experience working with many modern locked ECUs and understand the implications of opening and tuning them. In cases where tuning is not the best option, we can advise on safe alternatives such as OEM‑level repairs or software corrections.

How do you diagnose ECU and electrical faults?

We use advanced diagnostics, live data analysis and proven test procedures to trace ECU, wiring and sensor issues. This can include bench testing, oscilloscope work and software checks to pinpoint the root cause instead of just clearing fault codes. You can find more information about our approach on our ECU repair and diagnostics page.

Can you help with dashboard or instrument cluster faults?

Yes. We handle common dashboard and instrument cluster issues such as the well‑known Ford to Fiat 500 cluster faults, as well as other makes and models across the North East.

How do I book an appointment?

You can book by using the contact North East Remaps page on our website, calling us directly or sending a message with your vehicle details, location and the issue you are experiencing. We’ll advise the best next step and confirm a suitable time.
