Find and fix your underlying engine problems

Vehicle fault codes are a good indicator of what’s gone wrong. But they don’t tell the whole story. With our advanced diagnostics equipment and years of industry-leading experience, we can identify the root cause of your engine troubles and restore engine efficiency.

Pinpoint precision

Our advanced diagnostics go far beyond simple code reading. We use cutting-edge tools to perform in-depth analyses of sensors and actuators to find and fix what’s harming your vehicle.

Air leak detection

With our evaporative emissions control system (EVAP) smoke machine, we can locate the tiniest of air leaks in your vehicle’s fuel system. By patching these holes, we prevent harmful vapours from escaping and help you pass your MOT.

Engine checks

Our diagnostic services include:
- Engine checks
- Vehicle electrical systems
- Component programming
- Software updates

Advanced diagnostics

By analysing electrical signals using an automotive oscilloscope, we can accurately troubleshoot your fault codes to determine the necessary repairs and replacements for your problems. This helps us ensure we’re recommending the right solutions first time.

In addition to our ‘lab scope’, we also use an EVAP smoke machine to detect even the smallest of air leaks for effective emission-system repair.

Diagnostics FAQ

System efficiency diagnostics assess the overall performance of your vehicle’s systems, including the engine, transmission, fuel system and emissions.

By identifying faulty or inefficient areas, our technicians can perform repairs that improve fuel economy, reduce emissions and boost performance.

If you’re experiencing decreased fuel economy, loss of power, rough idling or increased emissions, it’s time to book a diagnostics appointment.

System efficiency diagnostics also ensures all systems are working optimally. This information supports your regular maintenance and helps you pass your MOT.

During a system efficiency diagnostics appointment, our technicians evaluate your:

  • Fuel injectors
  • Oxygen sensors
  • Spark plugs
  • Ignition system
  • Exhaust system
  • Related emissions components

Our comprehensive vehicle diagnostics test aims to identify any and all issues affecting the efficiency and performance of your vehicle.

Most diagnostics appointments take around 1-2 hours to complete.

The cost varies depending on your vehicle’s emissions rating. But diagnostics typically lead to long-term savings through improved fuel efficiency, reduced maintenance costs and reduced risk of vehicle breakdown.
