2010 AUDI S5 CABRIOLET Engine Problems

WHEN STARTING THE CAR, THE ENGINE WOULD CRANK FOR SEVERAL SECONDS AND SOMETIMES WOULD NOT START AT ALL UNTIL RESTARTING THE IGNITION SEQUENCE. WHILE AT A STOP, THE CAR WOULD JUMP SUDDENLY AFTER A DELAY OF PRESSING THE GAS PEDAL AND THE IDLE WAS VERY UNEVEN. AFTER TURNING THE CAR OFF, THE SMELL OF GASOLINE WOULD PERMEATE AROUND THE VEHICLE FOR A LONG TIME, MAINLY COMING FROM THE ENGINE AREA. WHEN OPENING THE HOOD, THE ENTIRE ENGINE COMPARTMENT HAD A SHINY APPEARANCE ALMOST AS IF A MIST OF GAS OR SOLVENT COVERED EVERY SURFACE. EVENTUALLY A SMALL POOL OF GAS WAS VISIBLE SITTING ON TOP OF THE ENGINE UNDERNEATH THE SUPERCHARGER. THE AUDI DEALERSHIP EVALUATED THE LEAK AND DETERMINED IT TO BE THE FUEL RAIL WHICH HAS BEEN KNOWN TO LEAK IN SIMILAR V6 3.0 AUDI ENGINE MODELS
