2005 BMW 645CI Engine Problems

I OWN A BMW 645CI 2005 CONVERTIBLE I HAVE ISSUES YES ISSSUES WITH THIS VECHILE, FIRST ISSUE IS THE INFAMOUS IDRIVE THAT NEVER REALLY WORKED PROPERLY SINCE I PURCHASED THE CAR, IT BLINKS ON AND OFF FOR 30MINS THEN IT WOULD MAGICALLY COME ON UNTIL ONE DAY IT JUST DIDN'T COME BACK ON THIS WAS AFTER A TRIP TO THE DEALER TO GET THE CONVERTIBLE TOP LOCK REPROGRAMMED.. SO THE CAR WAS INCLUDED IN THE LAWSUIT SO I TAKES IT TO THE DEALER FOR THE REPROGRAMMING AND MY CAR CAME OUT WORST THEN IT WENT IN THE IDRIVE NEVER WORKED TO THIS DAY WHICH IS 04/16/2018, MY TOP ONLY OPENS WITH THE PASSENGER SIDE DOOR SLIGHTLY OPENED YES THE DOOR HAS TO BE OPEN FOR THE TOP TO OPERATE... THIS IS WHAT THE DEALER TOLD ME SO I WAS SO CONFUSED OF WHAT THE REPROGRAMMING WAS FOR ? I NEED...

I WAS DRIVING ON THE HIGHWAY AND MY BMW 645 FAULT MESSAGE DISPLAYED (TRANSMISSION RELATED MALFUNCTION,DRIVE MODERATELY). AFTER THAT,THE SERVICE ENGINE SOON LIGHT CAME ON,ALONG WITH A NEW FAULT MESSAGE THAT DISPLAYED (INCREASED EMISSION). AFTER THAT, THE CAR SPEED ABRUPTLY WENT FROM 60, TO (WHAT FELT LIKE FIRST GEAR),THEN JUST CUT OFF!! THERE WERE CARS AND TRUCKS ALL AROUND ME,DOING THE SPEED LIMIT OF 60 OR HIGHER,JUST MISSING ME,WHILE I'M SITTING STUCK IN THE MIDDLE OF THE HIGHWAY!! I PROCEEDED TO RESTART THE CAR,AND IT STARTED, WITH NO FAULT MESSAGES;NO SERVICE ENGINE LIGHT; AND DROVE FINE FOR A FEW DAYS,AND THEN DID THE SAME THING AGAIN!! I TOOK THE CAR TO A BMW REPAIR SHOPPED TO HAVE THE FAULT CODES READ, WHICH END UP BEING A LONG LIST OF CODES, THAT THE MECHANICS COULD NOT FIND THE REAL CAUSE OF THE ISSUE. SO,I HAD THE SHOP REPLACE MY SPARK PLUGS;...

WATER STARTED LEAKING FROM THE CAR AND ONCE CHECKED FOUND THAT THE ALUMINUM PIPE UNDER THE INTAKE HAD A CRACKED IN IT AND HAD TO REPLACE THE PIPE WITH A NEW METAL PIPE, WHICH COST ME 1500.00 AND THE BMW MECHANIC STATES MOST OF ALL THESE CARS EXPERIENCE THIS SAME PROBLEM, WHICH CAN LOCK UP YOUR MOTOR OR CRACKED THE HEADS ON IT. *TR
