You may be wondering what exactly is involved in car diagnostic services. When your mechanic carries out a vehicle diagnostic test, usually they will be checking for any problems with your vehicle using a diagnostic tool. Once the diagnostic software is introduced to your vehicle’s OBD port, a range of problems may be revealed. These can include anything from oil tank issues to transmission and exhaust system issues or engine problems, among others.


Most modern vehicles will have an onboard computer processor as well as microchips and sensors that work in conjunction with the mechanic’s car diagnostic scanning software to enable identification of any vehicle problems.

What Are the Benefits of Car Diagnostic Services?

Car Diagnostics are incredibly beneficial in a variety of ways. Simply put, they enable the easy identification of vehicle malfunctions so that the mechanic can repair them more quickly.


When something goes wrong in your vehicle, a fault code will be recorded in the vehicle’s computer memory. The mechanic can then identify the issue via its corresponding code, everything from faulty windscreen wipers to more serious problems like suspension issues. This accurate and fast diagnosis will ultimately save you time and money, especially since you can have minor issues rectified before they become more expensive.

What Issues Can Car Diagnostics Identify?

A few of the areas of concern a car diagnostics service can identify in most vehicles are as follows:

  • Issues with the engine

  • Engine timing problems

  • Fuel injector performance

  • Engine RPM levels

  • Air and coolant temperature

  • Crankshaft issues

  • Camshaft position

  • Problems with brakes

  • Engine management problems

How Often Should I Have Car Diagnostics Carried Out?

You should definitely book car diagnostic services if you feel that something has gone wrong with your vehicle. Other than that, it is a good idea to have car diagnostics carried out once a year.
