Why is my 2007 BMW 328xi's engine oil pressure light on?

Hello, the low oil pressure light is an indication of a potential major internal engine concern. Testing is required to manually check for internal engine oil pressure. If it is too low, damage could already have occurred or be occurring to internal engine components that require constant lubrication. You could have an actual internal problem, or you could have an issue with the sensor that provides data to the gauges, illuminating the light.
