Are you worried about numerous warning lights popping up on your dashboard? Worry no more! Let Wychway garage’s team of highly trained experts quickly identify and troubleshoot your potential problems.

We use the very latest car diagnostics techniques and equipment which allow us to communicate directly with your vehicle’s onboard computers.

This combined with our high-level technical team of experts means we can access, identify and repair the faults on your car. In addition, our diagnostic system allows us to work on any make, model and age of the car. We have the very latest diagnostic kits for every car.


In the event that a warning light illuminates your dashboard, it is necessary to get a car engine diagnostic check. This will identify the fault and detail what will be needed to do in order to repair your vehicle.

All modern vehicles available today contain onboard computers referred to as an Engine Control Unit (ECU). This computer system continuously monitors, analyses and records the performance of the vehicle. It also controls various aspects of the vehicle such as engine temperature, windscreen wipers and even emission levels.

When there is a problem somewhere inside the car, sensors in the affected area promptly relay back information to the ECU which in turn, report an error code. These error codes are represented in the form of warning lights on the dashboard. Such errors can only be deciphered by trained personnel using specialist vehicle diagnostic equipment.

At Wychway we use state of the art diagnostic equipment which can decipher these error codes present in your ECU’s memory. From there our specialists can recommend the necessary remedies to get you back on the road safely and securely. This saves you the hefty sums you would likely have paid if the car went on to develop faults and damage.

Benefits of a Car Diagnostic Test

Before cars had ECUs, diagnosing problems was not only time consuming but also expensive. This was partly because, the owners of cars didn’t realise there was even an error (often an error is completely undetectable and without your dashboard lighting up, you’d still be in the dark) and so by the time they got their vehicle to the garage, the problem will have gotten worse and potentially much more expensive.

Car diagnostic tests can now discover minor and major problems long before they transform into bigger problems which will require expensive repairs, Worse still such defects could leave you stranded on the roadside after a breakdown.

Diagnostic tests can also check the onboard computer’s memory for stored data about the car’s history as well as important manufacturer notifications. This gives the technicians a complete and true picture to enable them to provide the best repair service possible.

When Should Diagnostics be carried out?

Why wait until your dashboard lights up to take your car for diagnosis? Taking a proactive approach when you sense something is not right can prove invaluable for your car maintenance and life span. Car diagnostics are not expensive and they’re quick!

Our technicians, however, recommend that you should bring your car for diagnosis at least once per year. This will help us uncover minor defects that can’t be heard, seen or that haven’t triggered the dashboard warning light.

A car diagnostics test should also be done before purchasing a second-hand car. This will ensure that you buy a clean car that has no underlying problems that might come to haunt you in future.
