Warning Lights We Can Help With
A diagnostic scan helps identify what the vehicle is actually reporting before you start replacing parts.
Engine Light
Check engine light, misfires, sensors and engine fault codes.
DPF Warning
DPF faults, soot loading warnings and emissions codes.
ABS Light
Wheel speed sensor, ABS module and braking system codes.
Battery Light
Charging system concerns, battery warnings and electrical faults.
Gearbox Fault
Automatic gearbox, transmission warnings and related codes.
Airbag Light
SRS, airbag, seatbelt and restraint system fault codes.
Temperature Warning
Cooling system warnings, overheating and sensor faults.
Limp Mode
Power loss, restricted performance and recurring warning lights.
Don’t Guess. Diagnose First.
A fault code tells you where the vehicle has detected a problem. It does not always tell you which part has failed. That is why the higher diagnostic options include live data checks, interpretation and, on Advanced Diagnosis, component testing where suitable.
What Advanced Diagnosis Can Include
This is the option for faults that need more than simply reading a code.
Component Testing
Accessible sensors, actuators or related components checked where suitable.
Electrical Checks
Basic voltage, earth, fuse or supply checks where relevant to the fault.
Live Data Comparison
Readings reviewed to see whether values look sensible for the fault.
Battery/Charging Test
Battery and charging system checks where warning lights or voltage faults appear.
Actuator Tests
Output tests carried out where the vehicle and diagnostic tool support them.
DPF Data Review
Soot, pressure and regen-related data reviewed where available.
Fault Logic
Codes, symptoms and readings combined to narrow down the likely cause.
Repair Direction
Clearer advice on what should be tested, repaired or replaced next.

Important To Know
Diagnostic scans identify stored faults, live data and likely causes. Some faults still require further testing before an exact failed part can be confirmed. If the fault is still present, a warning light may return after codes are cleared.
Diagnostic Scan FAQs
Can you clear warning lights?
Codes can be cleared where suitable, but if the fault is still present the warning light may return. Clearing a code does not fix the underlying issue.
What is the difference between the three options?
Fault Code Scan reads and explains codes. Diagnostic Report adds live data review, deeper explanation and written findings. Advanced Diagnosis adds extra time for component testing, sensor checks and basic electrical checks where relevant and accessible.
Does Advanced Diagnosis guarantee the exact failed part?
No diagnosis can guarantee every fault without limits, but Advanced Diagnosis gives a much stronger investigation than simply reading codes. Some faults may still need specialist testing, stripping down or garage equipment.
Do you come to me?
Yes, this is a mobile service covering Warrington and surrounding areas, subject to availability.
Do you scan DPF faults?
Yes, we can scan for DPF and emissions-related fault codes where the vehicle supports it. Advanced Diagnosis can include DPF data review where available.
Will a diagnostic scan tell me exactly what part to replace?
Not always. A diagnostic scan shows fault codes and live data that point towards likely causes. Some faults need further testing to confirm the exact failed component.
