Diagnostic Technology at Paul Harrison Cars

At Paul Harrison Cars, we invest in the latest automotive diagnostic technology.

We use this to accurately identify and repair faults on all makes and models — from everyday vehicles to high-performance and hybrid systems.

Over the last 15 years, vehicle technology has advanced rapidly. Most modern cars now feature multiple electronic control units (ECUs) that manage everything from braking and engine performance to climate control and safety systems. Some vehicles contain up to 35 or more CPUs, each responsible for different functions.

With this level of sophistication, it’s impossible for any workshop to service or repair modern vehicles without advanced diagnostic equipment. That’s why our garage is equipped with the latest dealer-level tools to deliver fast and precise diagnostic results, helping us complete repairs efficiently and minimise your vehicle’s downtime.
