Find the cause before replacing parts
A fault code is a starting point, not always the final diagnosis. We read stored and pending codes, examine relevant live data and check the electronic systems involved before explaining the next steps.
Problems we investigate
- Engine management and warning lights
- ECU communication and network faults
- Reduced power or limp mode
- Starting, sensor and actuator-related faults
- AdBlue, DPF and EGR system warnings
Diagnostics before remapping
A vehicle with unresolved faults should be assessed before performance tuning. Our health checks help identify issues that may make remapping unsuitable until repaired.
