C1391 can end up being a fairly generic code that tends to come up when the engine is not producing the torque the ABS/ESP was expecting.
Therefore it's likely an indirect symptom that there's an engine issue brewing.
Take live data readings, look for any split hoses, loose connectors, have a look at the fuel filter- difficult one to diagnose without getting stuck in personally sorry.
