Workshop-Based Diagnostics & ECU Support

AdBlue, EGR & DPF ECU Solutions

Diagnostics-led support for warning lights, countdown messages, limp-mode issues and repeated system-related faults.

We assess the vehicle, stored fault codes and current system status before recommending the most suitable route. This may include further diagnosis, repair advice, resets, regeneration support or an appropriate ECU software solution.

If possible, include a photograph of the dashboard message and any stored fault codes. This helps us provide more accurate advice before you travel to the workshop.

SCR & AdBlue Fault Support

AdBlue System Solutions

Diagnostics-led support for AdBlue warning messages, countdowns, no-start restrictions and system-related fault codes. We assess the vehicle’s current status before recommending repair, reset or an appropriate software route.

AdBlue warning message No-start countdown NOx sensor faults Pump or pressure faults Heater or injector faults Reductant system codes

Diagnose the System

We review the registration, dashboard message, stored fault codes and previous repair history before advising on the next step.

  • Full diagnostic scan
  • Fault-code and status assessment
  • Review of recent repairs
  • Check for related engine faults

Check Countdown Status

An active mileage or no-start countdown must be identified and, where possible, reset before any supported ECU programming work.

  • Remaining mileage or starts checked
  • No-start status assessed
  • Reset or initialisation attempted where supported
  • Additional diagnostic work confirmed first

Choose the Right Route

The correct route may involve wiring diagnosis, component repair, sensor replacement, system reset or an eligible non-road software option.

  • Repair or replacement advice
  • Reset route where supported
  • Vehicle-specific compatibility check
  • Off-road software option where eligible

Send Your Reg & Dashboard Message

Include any stored fault codes and tell us whether a countdown is active. Additional diagnosis or reset work is quoted separately where required.

Understanding the EGR System

Diagnose the Cause Before Choosing the Route

The EGR system recirculates a controlled amount of exhaust gas into the engine to reduce certain emissions. Faults can involve the EGR valve, position sensor, cooler, wiring, airflow readings, intake contamination or related components.

EGR System Diagnosis

EGR Delete Solutions

EGR-related warning lights and drivability problems are not always caused by the valve alone. We begin by reviewing the fault codes, symptoms and intended use of the vehicle before recommending the appropriate route.

Common EGR-Related Symptoms

Engine warning light EGR flow or position codes Reduced power Limp mode Poor throttle response Carbon contamination
Review the fault information

We check the registration, warning message, symptoms and stored diagnostic fault codes.

Identify the appropriate route

Depending on the fault, the vehicle may require further diagnosis, cleaning, component repair or replacement.

Off-road software option where eligible

EGR-disable software is only considered for appropriate non-road, competition or motorsport applications.

Diagnostics, Cleaning & DPF Support

DPF Solutions

Our main objective is to identify why the DPF is struggling to regenerate and retain the original filter wherever practical. DPF TerraClean is our primary cleaning route, supported by further diagnosis where another fault is causing the blockage.

Workshop-Based DPF Support

Our Preferred Approach

Diagnose. Clean.
Retain the Original DPF.

Assess the cause, check suitability and select the right cleaning or repair route.

Find the Cause.
Choose the Right Route.

A blocked DPF is often the result of repeated short journeys, failed regenerations, sensor problems, engine-temperature issues or another underlying fault. Cleaning the filter without addressing the cause may allow the problem to return.

DPF Assessment

Diagnosis Available

We review the fault codes, warning lights, regeneration history and available DPF data before recommending cleaning or further work.

  • DPF and engine fault-code scan
  • Soot-loading and regeneration review
  • Pressure and temperature data where available
  • Assessment of potential underlying faults

Subject to suitability

A dedicated TerraClean DPF cleaning process for suitable filters affected by accumulated soot and restricted flow.

  • Vehicle suitability checked first
  • Dedicated TerraClean DPF-cleaning equipment
  • Filter retained on the vehicle where appropriate
  • Post-clean checks and regeneration assessment
Where Required

Further Diagnosis

Quoted Separately

If cleaning alone will not resolve the issue, we can investigate related faults or advise on off-vehicle cleaning and replacement.

  • Sensor and wiring fault investigation
  • Regeneration-prevention diagnosis
  • Off-vehicle ash or oil cleaning route
  • Replacement advice for damaged filters

Send Your Reg & DPF Fault Details

Include the dashboard warning, stored fault codes, recent repair history and whether the vehicle is currently in limp mode. We will advise whether assessment, TerraClean or further diagnosis is the best starting point.

Get the Right Advice First

What to Send Us

The quickest way to receive useful advice is to send us your registration number, exact warning message, fault codes and recent repair history. This allows us to understand the fault picture before recommending diagnosis, cleaning, repair or another appropriate route.

01 Required

Your Registration

Send the full registration number so we can identify the correct vehicle, engine, production year and ECU platform.

02 Important

Dashboard Message

Tell us the exact warning message, remaining mileage or number of starts. A clear photograph of the dashboard is helpful.

03 If Available

Fault Codes & Photos

Include diagnostic fault codes, scan reports, screenshots or photographs of any relevant components or warning messages.

04 Useful

Previous Work

Tell us about parts already replaced, recent repairs, unsuccessful regenerations, previous cleaning or other diagnostic work.

Example message

“Hi Alex, my registration is AB12 CDE. The dashboard shows [exact warning message]. The symptoms are [details] and the stored fault codes are [codes]. The vehicle has already had [previous repairs or replaced parts]. Can you advise on the best route?”

Send Your Details to RPM Sussex

WhatsApp is normally the easiest option when sending registration details, dashboard photographs, fault codes and diagnostic reports.
