Frequently Asked Questions
A car diagnostic service connects your vehicle to advanced scan tools that read data from onboard systems like the engine, transmission, brakes, and electrics. Our technicians interpret the fault codes, inspect relevant components, and run tests to pinpoint performance issues. You’ll receive a detailed digital report with our findings and recommendations. Diagnostics remove the guesswork and allow for more precise car repairs. It’s a critical first step in resolving any car problem.
You should book a diagnostic service at the first sign of warning lights, engine hesitation, rough idling, or poor fuel efficiency. Even subtle symptoms can point to deeper issues that may worsen over time. Diagnostics help identify these problems early, so you avoid unexpected breakdowns and expensive repairs. The longer issues go unchecked, the more damage they can cause. Regular checks offer peace of mind and help extend your vehicle’s lifespan.
Most diagnostics take 45 to 90 minutes, depending on the type of issue and your car’s make and model. While some faults are quick to detect, others may require deeper analysis or further testing. At Cox Auto, we balance speed with thoroughness to ensure no detail is missed. You’ll get your results clearly explained in plain language. We never push unnecessary repairs; we just give honest advice based on accurate data. If repairs are needed, we’ll outline timelines and costs before proceeding.
Our diagnostic report outlines the scanned systems, any error or fault codes found, what they mean, and what might be causing them. We’ll also include technician notes and recommended next steps, such as part replacements or system resets. It’s written in language that’s easy to understand, not just for mechanics. If multiple issues are present, we’ll prioritise them for safety and urgency. You’re welcome to ask questions; we believe in full transparency. We’ll also store the report for future service reference.
In many cases, yes, especially if the problem is simple and parts are in stock. Diagnostics allow us to act quickly with a clear game plan. If the issue is more complex or requires special parts, we’ll book you in at the earliest opportunity and keep you informed. We’ll explain every option clearly, including costs, so there are no surprises. Repairs only proceed with your approval. Our goal is to get you safely back on the road as soon as possible.
