The fuel pressure sensor can be attributed to a whole host of running and failure problems - from hard starting, poor idle, loss of performance, and all the way to limp mode and complete shutdown. This sensor monitors fuel line pressure ahead of the fuel rail. A false reading will cause the ECU to make erroneous corrections or maybe even put the car into limp mode. In almost all cases, a check engine light and fault code will be present for the low pressure fuel sensor. You may also have "Increased Emissions" message on your iDrive. Luckily, this sensor is not very expensive and easy to replace on most models. It's cheap enough to keep one as a spare.
