Have had the new Airpump installed am now using the car daily, started hearing a hissing noise now and again after going over rough roads, it seems to settle down as I reach smoother roads, tends to happen more after the vehicle has been stopped and then driven away, sounds like its coming from offside (Driverside UK) area, is this anything to worry about? I am still under warranty so need to be certain?
