What’s Included in a Car Diagnostic Service
Our complete car diagnostic service includes:
Advanced Car Scanning
We connect to your car’s onboard computer system (ECU or ECM) using professional OBD2 (On-Board Diagnostics) tools. These scanners detect and read diagnostic trouble codes (DTCs) to pinpoint problems in your engine, transmission, braking system and more.
Check Engine Light Diagnostics
We investigate dashboard warning lights and identify the exact cause of the issue, helping you avoid unnecessary repairs and downtime.
Real-Time Data Monitoring
We assess live data from critical sensors like engine temperature, airflow, fuel mix, throttle position and charging system to detect issues not flagged by fault codes alone.
Comprehensive System Testing
We evaluate all major systems including ABS, airbags, emissions control and battery health to ensure everything is running as it should.
Diagnostic Report and Next Steps
You’ll receive a clear summary of results and practical advice on any required repairs, with no confusing jargon.

When Should You Get a Car Diagnostic?
Car diagnostics aren’t just for emergencies. Book a scan when:
- The check engine light or other warnings appear
- You notice strange noises, stalling or sluggish acceleration
- You’re buying a used vehicle and want peace of mind
- As part of regular servicing for early problem detection
Catching faults early saves money and keeps your car running reliably.
How Car Diagnostics Work
Car scanning involves reading data from your vehicle’s onboard computer using a scan tool. Depending on the system, this may include:
- Handheld OBD2 scanners (basic to advanced workshop tools)
- Workshop-grade diagnostic computers
- Bluetooth OBD apps for mobile pairing
Our team uses professional tools and up-to-date software to provide accurate, fast results at your location or in our workshop.

Frequently Asked Questions – Car Diagnostics
How long does a car diagnostic take?
Typically 30 to 60 minutes, depending on the issue and how many systems need to be scanned.
Can you clear my check engine light?
Yes, but only after confirming and resolving the underlying issue to prevent further damage.
Can I get a car diagnostic if my car won’t start?
Yes. We can still scan for fault codes and run checks to identify starting issues.
Is a mobile diagnostic as accurate as a workshop scan?
Absolutely. We use the same workshop-grade equipment and software for both.
Does the scan include all systems?
Yes. We check the engine, transmission, ABS, airbag, battery, emissions and more.
Will a diagnostic tell me exactly what needs fixing?
In most cases, yes. The scan shows fault codes and sensor data, and our mechanics use this to identify the root cause and recommend next steps.
