Understand Your Engine Warning Lights
Each day we receive enquires regarding what issues the various dashboard warning lights can relate to. Some of these lights can be easily disregarded, but others require a bit more investigation or possible repair by one of our Bosch accredited master technicians. Last thing we want in our busy lives is a visit to the garage when it may not be necessary, but more importantly we don’t wish to be stuck at the side of the motorway if the warning light issue develops into something more problematic, so here is a guide that helps you to better understand what fault, if any, your car maybe suffering from.
Oil Pressure Warning – this light will illuminate when the oil pressure sensor detects low oil pressure, the vehicle’s engine should be switched of immediately to avoid severe engine damage and the oil level checked to ensure correct quantity in the engine. Professional help should be sought if oil level is correct and light continues to show. Amber light’s can also be used in some vehicles to warn when the oil level is getting low and a top up is required.
Battery Warning – This means the vehicle has stopped charging the battery and will eventually go flat. Seek professional help to resolve the issue.
