It used to be that there were relatively few things to look at when the check engine light came on or you were experiencing performance issues. Today’s vehicles are far more complex, so engine diagnostics are more involved. At TRC Automotive, we have the equipment and talent to ascertain what is going on with the engine of your foreign or domestic vehicle. Our experience with engine diagnostics enables us to move quickly through what is wrong to getting it resolved so you can be back to your errands in the Belmont, North Carolina area.

We recommend not necessarily waiting until you see a check engine light before having engine diagnostics run. There are several minor issues that won’t trigger the engine light. An annual checkup isn’t a bad idea so you can get ahead of any issues that could be affecting fuel mileage, performance, or could become a bigger issue. We also recommend having us perform engine diagnostics on a used car you are considering purchasing. The seller should allow this, but if they do not, that in itself is a good reason to walk away because it demonstrates that they know of an issue that they don’t want you to learn about.

Engine diagnostics are a valuable tool when combined with our experience in automotive services. Any repairs can be initiated with confidence that they are what is needed to get your vehicle working as it should. If you would like to know more about our services or would like to schedule engine diagnostics, don’t hesitate to reach out to us.
