2002 BMW 540I Engine Problems

AFTER STARTING UP MY CAR, THERE WAS A SLIGHT WHINE UNDER THE HOOD. I GAVE THE CAR A LITTLE BIT OF THROTTLE TO SEE IF THE WHINE WENT AWAY AND HEARD A LOUD BANG. THE CAR WAS STILL RUNNING BUT MY BATTERY LIGHT WAS ON. I NEEDED TO GET HOME, AND I THOUGHT THAT MY CAR MAY NOT START AGAIN IF I TURNED IT OFF SO I DROVE HOME. IMMEDIATELY I NOTICED THAT I DIDN'T HAVE ANY POWER STEERING. AS I DROVE MY ENGINE TEMPERATURE GOT HIGHER AND I BARELY MADE IT HOME WITHOUT OVERHEATING. A FEW DAYS LATER I LOOKED IN THE ENGINE COMPARTMENT AND SAW THAT THE POWER STEERING PUMP HAD BROKEN FREE OF THE ENGINE - THE BRACKET HAD SHEARED OFF. THAT IN TURN CAUSED THE BELT TO FALL OFF WHICH WAS TURNING THE WATER PUMP AND ALTERNATOR. I GOT ON THE COMPUTER AND LOOKED UP THE...

I WAS DRIVING IN STOP AND GO TRAFFIC WHEN I NOTICED THE STEERING FELT A LITTLE STIFFER THAN USUAL. AFTER ABOUT 5 MILES AND BETTER FLOWING TRAFFIC I PULLED INTO A RESTAURANT FOR DINNER WHEN MY UPPER RADIATOR HOSE EXPLODED. I PULLED INTO A STALL AND OPENED THE HOOD TO INSPECT WHAT HAPPENED. THE HOSE WAS VERY APPARENT AND AFTER FURTHER INVESTIGATION I NOTICED THE POWER STEERING PUMPS PULLEY AT A VERY SHARP ANGLE COMPARED TO LINEAR WITH THE SERPENTINE BELT. I CAN ONLY ASSUME THAT FROM THE BRACKET ON THE PUMP BREAKING, IT CAUSED A CHAIN REACTION OF EVENTS. FIRST THE BRACKET BROCKET PUTTING THE PUMP AT A STEEP ANGLE N FORCING THE BELT TO GO OFF TRACK WHICH THEN CAUSED ALL THE OTHER ACCESSORIES TO BE DISABLED INCLUDING THE WATER PUMP WHICH OVERHEATED THE CAR. *TR
