Basic
Best for reading fault codes£4920–30 mins
- Mobile plug-in OBD scan
- Engine warning-light check
- Stored and pending codes where supported
- Basic fault-code explanation
- Codes cleared where suitable
- Simple next-step advice
A code points to a system or condition; it does not always identify the failed part.
Full
Best for understanding the fault£7945–60 mins
- Everything in the Basic scan
- Broader system scan where supported
- Relevant live-data review
- Freeze-frame data where available
- Likely causes explained clearly
- Written findings included
- Repair-priority guidance
Recommended when you want more than a list of codes.
Advanced
Best for deeper investigation£129up to 90 mins
- Everything in the Full option
- Accessible component testing
- Sensor-signal checks where suitable
- Basic relevant electrical tests
- Battery and charging test if needed
- Supported actuator tests
- Stronger repair direction
Testing depends on the fault, vehicle support, access and available time.
The important distinction
A fault code is a clue—not a parts list
Reading a code is the starting point. The code records what the vehicle detected, but several faults can trigger the same code. The Full and Advanced options add interpretation and testing to provide a more useful repair direction.
Warning lights and symptoms
Problems vehicle diagnostics can investigate
Coverage depends on the vehicle and which control systems support diagnostic communication.
Engine light
Misfires, sensor faults and engine-management codes.
DPF warning
Soot-loading, pressure and emissions-related faults.
ABS light
Wheel-speed, braking and module communication codes.
Airbag light
Airbag, seatbelt and restraint-system fault codes.
Battery warning
Charging-system and voltage-related concerns.
Gearbox fault
Transmission warnings and supported gearbox codes.
Temperature warning
Cooling-system warnings and related sensor faults.
Limp mode
Restricted power, boost faults and recurring warnings.
Advanced investigation
When a scan alone is not enough
Advanced Diagnosis adds practical testing time to combine the code, symptom and available readings.
Live-data comparison
Relevant readings reviewed to see whether values make sense for the symptom.
Component testing
Accessible sensors, actuators or related components checked where suitable.
Electrical checks
Basic supply, earth, fuse or voltage checks where relevant to the fault.

Common questions
Diagnostic scan FAQs
What is the difference between Basic, Full and Advanced?
Basic reads and explains stored codes. Full adds broader scanning, relevant live-data review and written findings. Advanced adds more time for accessible component, sensor and basic electrical testing where relevant.
Will a scan tell me exactly which part has failed?
Not always. A fault code records what the vehicle detected and can have several possible causes. Further interpretation or testing may be required to identify the failed component.
Can you clear warning lights?
Codes can be cleared where suitable, but clearing a code does not fix the underlying fault. If the problem remains, the warning light may return.
Do you diagnose DPF faults?
DPF and emissions-related codes can be scanned where supported. The Full or Advanced options can include relevant data review where available.
Do you come to the vehicle?
Yes. This is a mobile service covering Warrington and surrounding areas, subject to availability and safe access.
Does Advanced Diagnosis guarantee the exact fault?
No diagnostic service can guarantee every fault within a fixed visit. Some problems need specialist equipment, dismantling, extended testing or workshop access.
