What is a diagnostic?

A diagnostic test is a service performed by a mechanic to discover problems in a car. There are a diverse range of issues which can be discovered during a diagnostic and it is a vital aspect of car repair.

A diagnostic test requires a piece of equipment which plugs directly into a car and connects with the on-board measurement tools.

For example, there are processors, sensors and microchips inside a car engine and a connected on-board computer in most modern cars.

A diagnostic kit will connect to all of the sensors when it is plugged into a car and analyse the health of key components.

Once the machinery has done its job, a detailed report will be generated which will provide information which will tell the mechanic what is wrong with the car.

Why do I need a diagnostic?

As a service, a diagnostic is vital for finding faults quickly. It is a service you will have to pay for as it takes time and skill to carry out, however, it is significantly quicker than manually checking every single part of a car which is how they used to be carried out.

A diagnostic test will be able to find problems which may be totally undetectable to a mechanic, furthermore, a diagnostic could tell a mechanic that a problem is developing before it turns into a serious issue.

Having a diagnostic carried out can save you a huge amount of money in the long term as the longer a problem goes without attention, the worse it will get.

Think about how important it is for doctors to use machines to measure the health of your body. They’ll use an X-Ray to look at bone integrity, an ECG machine to look at your heart and a CAT Scan machine to see the brain.

A diagnostic machine performs the same function for a car.

Why do I have to pay for a diagnostic?

The cost of a diagnostic is required as it takes time and mechanics charge for labour. The cost will depend on a number of factors including the type of car and garage. Dealership garages may carry a higher charge than an independent garage, however, the only way to find out how much a diagnostic will cost for you, is by using WhoCanFixMyCar!
