Vehicle Diagnostics by Rayner Bosch Car Services

We've all been there, you start the car up and one of the dashboard lights which normally goes out doesn't this time. Or you're in the middle of a journey and a light suddenly pops up on the dashboard that wasn't there before! The likelihood is that your engine management system has identified a fault somewhere. This is not necessarily a bad thing, UNLESS you ignore it. But don't worry, our Vehicle Diagnostics Centre in Newbury has the equipment and trained technicians to find out what's going on.

The reality is more cars have onboard ECU's (Engine Control Units) now than ever before. These control and gather data on many of the vehicles essential components. They're complex but control the precision parts and help your vehicle operate faultlessly. To a point! With this complexity, fast, effective fault analysis and diagnostics is key. Without it, the subsequent professional repair (or maintenance) becomes increasingly difficult.

We are provided with live data so we can check in real time whether the problems identified are genuine ECU issues or as a result of a sensor error. If this is the case the solution could be to replace the sensor which would be much cheaper and quicker. We also have the facility to reset service and error lights that appear on the dashboard.
