Customer feedback

We take pride in our service, but don’t just take our word for it.

  • Booked my car in for a pretty big service including pink slip for rego. From beginning to end Campbell was so thorough and a really good communicator. As someone w an intellectual disability it meant so much having him clearly explain everything to me before he went ahead and did the works. Including answering any questions this gal had. Upon collection, Peter was fab as always, my car was sparkling clean, a courtesy H2o was in my car + my car was driving the best it has in a long time. Almost as good as a Rolls Royce some may say 😉 🚘 😄

  • The guys at Robert Street Automotive displayed exceptional customer service, professionalism and expertise. They helped my partner and I when we ran into car troubles on an important and busy day. They went above and beyond to make sure we were taken care of, and their turn-around time for repairs, as well as their communication regarding them, was fantastic. A special thank you to James. We’d highly recommend.

Frequently asked questions

How often should I schedule a vehicle diagnostic check?

Regular diagnostic checks, typically every 12 months or as recommended by your manufacturer, help detect minor issues before they become costly problems. Routine diagnostics keep your engine, transmission and electronic systems running efficiently and ensure your vehicle’s reliability and safety.

How do car diagnostics help prevent costly repairs?

Car diagnostics detect problems early, before they become major failures. By identifying engine faults, transmission issues or electrical malfunctions quickly, a diagnostic service helps prevent expensive repairs, extends vehicle life and ensures optimal performance, safety and fuel efficiency.

Can vehicle diagnostics detect problems before warning lights appear?

Yes. Advanced diagnostic tools can identify subtle performance issues, sensor faults and system irregularities before the dashboard warning lights activate. Early detection allows timely repairs, improving safety, preventing breakdowns and saving on expensive repairs.

What is the difference between an engine diagnostic and a full vehicle diagnostic?

An engine diagnostic focuses specifically on engine-related systems such as fuel, emissions and performance sensors. A full vehicle diagnostic scans the engine, transmission, brakes, air conditioning and safety systems, providing a comprehensive overview of your car’s overall health.

Will a vehicle diagnostic improve fuel efficiency?

In some cases yes. Diagnostics can identify engine or transmission issues, sensor malfunctions or air/fuel mixture problems that reduce efficiency. Fixing these problems after a diagnostic check can restore optimal fuel economy and improve overall vehicle performance.
