What is an engine diagnostic?
An engine diagnostic is a detailed, data-driven evaluation of your engine’s health. It helps pinpoint issues accurately so that repairs are efficient and effective, saving time and money in the long run. Engine diagnostics can include:
- OBD2 Scan:
- The technician connects a diagnostic tool to your car’s onboard computer to retrieve Diagnostic Trouble Codes (DTCs).
- This helps identify problems like misfires, sensor failures, or emissions issues.
- Live Data Monitoring:
- Real-time data from various sensors is monitored (e.g., oxygen sensors, fuel trims, engine temperature, air-fuel ratio) to check how the engine is performing under different conditions.
- Visual Inspection:
- The technician inspects engine components, wiring, vacuum hoses, and connectors for wear, damage, or leaks.
- Component Testing:
- Specific parts such as the battery, alternator, spark plugs, ignition coils, fuel injectors, or mass airflow sensor may be tested individually if needed.
- Compression & Leak Tests (if required):
- Checks for internal engine problems like worn piston rings or faulty valves.
- Emissions System Check:
- Ensures components like the catalytic converter, EGR valve, and oxygen sensors are working properly and emissions are within legal limits.

When would I need an engine diagnostic?
You will likely search for ‘engine diagnostic near me’ when your car shows signs of a problem that can’t be easily identified just by looking or listening. Modern vehicles rely heavily on electronic systems, so diagnostics help pinpoint faults quickly and accurately.
Common Signs You Need an Engine Diagnostic:
- Check Engine Light Comes On:
- This is the most obvious sign. It indicates the engine control unit (ECU) has detected a fault.
- Unusual Noises:
- Knocking, tapping, or clicking sounds from the engine may signal internal issues.
- Poor Performance:
- Sluggish acceleration, reduced power, or rough idling can point to engine, fuel, or ignition problems.
- Increased Fuel Consumption:
- A sudden drop in fuel efficiency may be caused by faulty sensors, misfires, or fuel system issues.
- Smoke from Exhaust:
- Excessive black, white, or blue smoke can indicate oil burning, coolant leaks, or fuel mixture problems.
- Stalling or Difficulty Starting:
- Can be caused by issues with ignition, fuel delivery, or sensors.
- Failed Emissions Test or MOT:
- A diagnostic can help find out why your vehicle failed and what needs to be fixed.
- Dashboard Warning Lights (besides check engine):
- Lights related to emissions, oil pressure, or battery could also justify a diagnostic.
Pro Tip: Even if no warning lights are on, you can request a diagnostic as preventive maintenance—especially before a long trip, MOT test, or if you’ve bought a used car and want to check its health. You should get an engine diagnostic any time your vehicle is behaving unusually, the check engine light appears, or you’re experiencing performance issues. It’s the most reliable way to identify and fix problems before they become more serious or costly.

How much should an engine diagnostic cost near you?
In the UK, the cost of an engine diagnostic typically ranges from £40 to £80 for a basic scan, which involves reading fault codes using an OBD2 scanner. More in-depth diagnostics, which may include testing individual components like sensors or the fuel system and sometimes a road test, can cost between £80 and £150 or more, depending on the complexity.
Chain garages usually charge around £50 to £70, while independent garages will offer lower prices, especially outside major cities. Some auto parts shops or mobile mechanics may provide free basic code scans, but these won’t include thorough diagnostics. It’s also common for garages to deduct the diagnostic fee from the final repair cost if you choose to have the work done with them. Always confirm whether the quoted price includes VAT and labour, and ask exactly what the diagnostic covers before committing.
