Car Engine Diagnostic Test
Do you have a flashing Check Engine light or a mystery warning symbol on your dashboard?
Don’t ignore it, it could be a signal of a serious issue with your engine, brakes, exhaust system, or other critical components.
At MRC, we offer professional car diagnostic checks using advanced equipment to read your vehicle’s fault codes. These tests identify problems quickly, helping prevent breakdowns or costly repairs. Most scans take under 90 minutes and provide a detailed report to explain any dashboard warning lights.
What Is a Diagnostic Fault Code Check?
A Diagnostics Fault Code Check is a quick and efficient way to identify problems within your vehicle when a dashboard warning light or error code appears. It helps pinpoint issues before they cause more serious — and expensive — damage.
- Engine Management Systems (EMS)
- Engine Control Modules (ECM)
- Electronic Control Modules (ECM)
These ECUs monitor everything from fluid levels to engine temperature using sensors placed throughout your vehicle. When something isn’t right, the ECU logs a fault code and triggers a dashboard warning.
At MRC, we use advanced Bosch OBD II diagnostic scanners to read these fault codes and understand the exact issue — something a standard driver can’t do without specialist tools.
Why Is a Diagnostic Check Worth It?
- Quickly identifies issues in your engine, brakes, exhaust, or electrical systems
- Helps avoid breakdowns and costly repairs
- Can detect hidden issues not visible on the dashboard
- Typically costs less than major mechanical faults
- Essential for modern vehicles with advanced onboard electronics
What Are Dashboard Warning Lights?
Dashboard warning lights are designed to alert you to potential problems, ranging from simple reminders like low washer fluid to critical alerts like engine failure or brake system issues.
If you’re seeing a warning light you don’t recognise, a Diagnostics Fault Code Check at MRC can help you get answers fast.
What Does a Full Car Diagnostic Include?
A full car diagnostic test uses onboard diagnostics (OBD) technology to communicate with your vehicle’s internal systems and identify issues that may not be visible on the surface. It’s like giving your car a full health check — quickly and efficiently.
