What this mobile fault code reading service does

Modern vehicles store fault codes whenever certain problems are detected, from engine and emission issues to sensor faults and electrical problems. Dual Action Roadside offers a mobile vehicle fault code reading service that comes to you and connects to your vehicle’s diagnostic socket (typically OBD or OBD-II).

The aim is to read and record diagnostic trouble codes (DTCs), and where appropriate on request, attempt to clear codes, and provide a simple report so you can understand what systems are affected and discuss repairs with your chosen garage.

This service is ideal if:

  • A warning light has appeared on your dashboard.
  • Your car has gone into limp mode and you want to know why.
  • Your regular garage is fully booked and you want information first.
  • You cannot easily be without your vehicle for a full day of diagnostics.

You get insight without pressure to approve repairs on the spot.

How the mobile fault code reading works

The process is designed to be straightforward and informative:

1) You get in touch with your location, vehicle registration and a brief description of the symptoms or warning lights.
2) Your address in or around Watford, Harrow, Hemel Hempstead or St Albans is checked, and an estimated arrival time is given.
3) On arrival, the diagnostic tool is connected to your vehicle’s OBD/diagnostic port and communication with the control units is established.
4) Stored and current fault codes are read, noted and, where suitable and on request, cleared after recording.
5) You receive a clear explanation of what codes were found and which systems they relate to, along with a simple written or digital report you can share with your garage.
6) Where possible, general guidance is given on likely next steps, but all repair work is left to your chosen mechanic or specialist.

This approach gives you actionable information without tying you to a particular repair provider.

Important service notice and limitations

This is a fault code reading and basic diagnostics service, not a full, in-depth investigation or repair. Diagnostic trouble codes point to affected systems or circuits, but they do not always identify the exact failed part or root cause on their own. Interpreting codes correctly often requires further testing, wiring checks, live data analysis or component inspection by a qualified technician or auto electrician.

Key limitations to be aware of:

  • DA Roadside does not carry out mechanical repairs or complex electrical work as part of this service.
  • Some intermittent faults may not store a current code at the time of the visit.
  • Certain manufacturer-specific systems may have limited access depending on the vehicle and available software.

The goal is to give you a clear snapshot of what the vehicle’s control units are reporting, so your chosen garage can start from an informed position instead of from scratch.
