What is a Car Diagnostics Test and How Much Does it Cost?

Introduction

Regular car diagnostic tests can help identify potential issues with your vehicle before they lead to costly repairs. At Pantech Auto Technicians, we provide Guildford car diagnostics tests for drivers in and around Surrey. In this article, we will explain what a car diagnostics test entails and how much it typically costs.

What is a Car Diagnostics Test?

A car diagnostics test involves using specialized software to identify developing faults and problems within your vehicle’s engine and other systems. These issues can be detected through built-in processors, microchips, and sensors.

The Process of a Car Diagnostics Test

During a car diagnostics test, our technicians will thoroughly check various components and systems of your vehicle. This includes the engine, transmission, ignition coils, exhaust, oil tank, fuel injectors, throttle, coolants, airflow, and more.

It’s important to note that the diagnostics check does not include the cost of repairs, replacement parts, or recoding. If we determine that your vehicle requires repairs, we will provide you with fault codes, which you can use to obtain repair quotes from specialists.

A full car diagnostics test typically takes between one hour and 90 minutes to complete. However, if complex issues arise or certain components need to be removed for the test, the duration may increase. Please note that the time required for fixing any identified issues is not included in the test duration.

Cost of a Car Diagnostics Test

The cost of a car diagnostics test varies depending on the location within the UK and the type of establishment you visit. Additionally, the price may be influenced by the specific car model, as some models may require more advanced equipment for the test. Luxury cars, unique vehicles, and sports models might also incur higher costs due to the additional time required for testing. On average, the standard cost ranges from £50 to £100.

Why Regular Car Diagnostics Tests are Important

It is highly recommended to have your vehicle undergo regular car diagnostic tests to prevent major problems from occurring. By detecting minor issues early on, you can address them before they escalate into costly repairs amounting to hundreds or even thousands of pounds. This proactive approach proves to be more cost-effective than waiting for your vehicle to break down before seeking a mechanic’s assistance.

Understanding Diagnostic Trouble Codes

Most diagnostic codes are standardized and referred to as “OBD-II” (on-board diagnostics). These codes are triggered when a fault or malfunction is detected within a specific system. The code gets stored in your vehicle’s memory and can be accessed during a diagnostics test using specialized software.

There are over 200 fault codes that can be generated, and they typically fall into four main categories:

• Body codes (prefixed with B): cover components within the passenger compartment, such as airbags, air conditioning, comfort features, safety systems, and driver assistance.
• Chassis codes (prefixed with C): pertain to mechanical systems including suspension, braking, and steering.
• Powertrain codes (prefixed with P): relate to engine components, transmission, and drivetrain parts.
• Vehicle network codes (prefixed with U): focus on wiring, computer systems, and integration with sensors and other vehicle components.
