What Happens During a Mobile Vehicle Diagnostic?
When your dashboard warning light comes on—be it AdBlue, DPF, NoX, or another emissions fault—it can be hard to know what’s really wrong. A professional mobile vehicle diagnostic carries out a comprehensive scan of your van’s systems at your location, giving you clear answers and next-step solutions without a garage visit. Here’s exactly what happens during our on-site diagnostics service.
Why Mobile Diagnostics Are Essential
Modern diesel vehicles rely on multiple sensors and control modules to meet emissions standards and protect engine health. If one component fails or a code triggers, your vehicle may enter limp mode, refuse to start, or rack up expensive repair bills. Mobile diagnostics identify the root cause quickly—saving you time, money, and downtime.
Our Diagnostic Tools
We bring dealer-grade equipment—like CMD Flash, Autotuner, and OEM-level scan tools—directly to your driveway, depot, or roadside location. These tools communicate with every control module (ECU, SCR unit, DPF controller, NoX sensor block, etc.), read live data, and pinpoint fault codes. All data is captured in real time and backed up for future reference.
Step-by-Step Diagnostic Process
- Arrival & Setup: We park safely and connect our diagnostic laptop to your van’s OBD-II port.
- Full System Scan: We scan all modules—engine, SCR, DPF, NoX, EGR, fuel system—to gather active and historical fault codes.
- Live Data Analysis: We monitor live sensor values (AdBlue dosing rate, exhaust pressure, injection timing, etc.) to confirm component performance under load.
- Fault Interpretation: We interpret fault codes in context—differentiating a simple communication glitch from a failing AdBlue pump or clogged DPF.
- Client Consultation: We explain the findings in plain English, recommending a reset, AdBlue delete, DPF delete, or repair.
- Code Clearing & Verification: If the issue is a false alarm or sensor glitch, we clear the code and verify the fault doesn’t return in a short test drive.
Key Systems We Scan
- AdBlue/SCR: Fluid level, pump status, injector dosing and heater circuit
- DPF: Soot load, regen history, pressure differential sensor data
- NoX & Lambda Sensors: Emissions levels, sensor response times, ECU feedback
- EGR & Swirl Flaps: Valve positions, actuator feedback, error codes
- ECU Communication: CAN bus health, module connectivity, EEPROM checks
Real-World Example: Transit Custom Diagnosis
A customer’s Ford Transit Custom in Hinckley was stuck in limp mode after an AdBlue warning. We arrived, ran our full diagnostic scan, and discovered a faulty level sensor reading zero fluid despite a full tank. After resetting the sensor calibration and clearing codes, the van drove normally—no delete required.

FAQs
Q: Will you clear my DPF warning?
A: Yes—if it’s a false alarm or communication glitch, we can clear the code and verify via live data. For genuine blockages, we recommend DPF delete.
Q: How do you charge?
A: We charge a flat diagnostic fee on-site. Any additional fixes (deletes, resets, repairs) are quoted separately.
Q: Can you diagnose petrol vehicles?
A: Our tools support petrol OBD-II diagnostics too—ideal for DPF issues on 2015+ Euro-6 cars.
