Common Reasons
When to Book Car Diagnostics
These situations are perfect for a diagnostic scan before spending money on parts.
Warning Light
Check engine light on
The check engine light (yellow engine icon) is often non-urgent but indicates a fault code worth understanding.
Performance Issue
Engine hesitation or poor starting
Rough idle, hesitation on acceleration, or difficult cold starts often relate to specific fault codes.
MOT Failure
Failed MOT with fault codes
Before spending on repairs, understand the MOT failure reason and whether it's fixable or urgent.
Diagnostics Questions
Frequently Asked About OBD Diagnostics
Will diagnostics show if my car is safe to drive?
We read any fault codes and advise on whether the issue is safe to live with or needs urgent attention. Some faults are warnings, others are critical.
How long does a diagnostic session take?
Typically 30–60 minutes at your location. We read codes, explain them, and discuss next steps before leaving.
Will you fix the issue or just diagnose?
We diagnose and advise. Some fixes we can do on site (like loose parts). For complex repairs, we recommend a workshop or book a follow-up.
What if my car has no fault codes?
If there are no codes, we'll do a visual inspection and advise on any issues we observe. Sometimes intermittent issues don't show codes.
Can you clear fault codes permanently?
We can clear codes, but if the underlying issue isn't fixed, the code will reappear. We focus on diagnosing the root cause first.
Do you cover all 12 areas?
Yes. Diagnostics are available across all our weekend routes: Feltham, Bedfont, Ashford, Sunbury, Kingston, Hounslow, Twickenham, Richmond, Hampton, Hampton Hill, Hampton Court, and Brentford.
