For garages, the first action to undertake with any vehicle bought in for repair is a diagnostic check. This can often be a complex procedure, but to the customer it is seen as a simple ‘plug-and-play’ job. Some question why they should pay, leading garages to offer diagnostics for free. There has, therefore, been an increase in technologies, products and devices that can offer a quicker scan of a vehicle, with customer friendly readouts to offer more transparent checks. From wheel alignment to tyre tread reading, such devices are designed to get maximum information to the consumer, who then feels like they are making a more informed choice about the work required.
