2002 BMW 325XI Engine Problems

IGNITION SELANIOD ISN'T WORKING. WHEN I TURN THE KEY TO START THE CAR, THE IGNITION THINKS THE CAR HAS STARTED, BUT THE ENGINE DOESN'T TURN OVER. IT TAKES MULTIPLE TRIES TO GET THE CAR TO START.

THE CAMSHAFT POSITIONING SENSOR A CIRCUIT INTERMITTENT CAN GO BAD LEADING THE ENGINE TO STOP WORKING ALL TOGETHER THIS COULD CAUSE A VERY SERIOUS ACCIDENT IF DRIVING ON THE ROAD

BATTERY AND ALTERNATOR CHECKED GOOD WITH VARIOUS SERVICE PROVIDERS YET VEHICLE HAD A PERSISTENT BATTERY DRAIN WITCH WOULD ONLY APPEAR AFTER CAR WAS ON THE ROAD AND DRIVING. AFTER CAR STOPPED RUNNING DUE TO LOW BATTERY IT THEN WOULD NOT RESTART. NO WARNING LIGHTS WOULD COME ON UNTIL JUST A MINUTE OR TWO PRIOR TO ENGINE QUITTING. TOOK VEHICLE TO MONROVIA BMW IN MONROVIA CA AND WAS TOLD THAT ALTERNATOR WAS FAULTY. INSTALLED NEW (NOT REBUILT) SPECIFIED ALTERNATOR AND NEW BATTERY AND 5 MONTHS LATER SAME PROBLEM CAME BACK. FURTHER OWN PERSONAL INVESTIGATION FOUND THAT BMW IS AWARE OF A FAULTY ELECTRICAL SYSTEM DESIGN FLAW AND I WAS NEVER TOLD ABOUT FROM BMW TECH'S AT TIME OF INSPECTION AS TO THE POSSIBILITY OF A SYSTEM PROBLEM WHEN THE CLIMATE CONTROL "BLOWER MOTOR RESISTOR" OF "FINAL STAGE UNIT" (FSU) AND ITS INTERNAL RESISTOR FAILS. THIS PART HAS HUNDREDS OF WRITE UPS...
