I was dawdling around the back og the car, and the ignition was on II. Every 30 seconds or so I heard a noise coming from behind the car. It sounded like the rear suspension compressor switching on and off again for a few seconds. Since I don't have SLS I'm assuming it's the fuel pumps. Is it normal they run this regularly or is it indicative of a fuel leak or a bad accumulator ?
