Find the Fault, Fix it Fast
OSP Automotive & Marine offers a comprehensive EFI diagnosis in Grafton and mechanical fault diagnosis service. Using specialised diagnostic tools, we can assess the performance of your EFI system, detect any error codes or malfunctions and pinpoint the root cause.
We also provide an in-depth analysis of the mechanical components, such as the engine, transmission, brakes, suspension kits and other relevant systems, to detect any mechanical faults. If repairs are required, we carry out all mechanical repairs in-house using trusted parts.

Find the Fault, Fix it Fast
Modern vehicles are packed with electronics, sensors and complex systems—when something goes wrong, it’s not always obvious why. That’s why EFI and fault diagnosis is all about accuracy. We use advanced scan tools and hands-on experience to read error codes, identify faults and work out exactly what’s going on under the bonnet.
Whether it’s poor fuel efficiency, rough idling, misfires or a warning light that won’t quit, we’ll track the issue to its source. We don’t guess, replace parts blindly or upsell what you don’t need— we troubleshoot efficiently and explain our findings clearly.
From EFI systems to mechanical faults in the engine, transmission, brakes and more, we’ll get to the bottom of it.
If your vehicle isn’t performing the way it should, let us take a proper look.

As we work on your vehicle, we take extensive photos and videos of our findings so you can see what our technicians are fixing, and we have records of all maintenance and repairs completed.
