DRIVING AT 50 MPH I WAS BEING HARASSED BY ANOTHER MOTORIST BECAUSE I WAS DRIVING THE SPEED LIMIT. I DECIDED TO LET HIM PASS BUT FIRST I HAD TO SPEED UP TO 58 MPH INORDER TO COMPLETELY OVERTAKE A PASSENGER CAR TO MY RIGHT (PASSENGER SIDE) I GAVE THE THROTTLE SOME GAS AND THE CAR WENT NOWHERE. THE NEEDLE WENT ALL THE WAY INTO THE RED ZONE ON THE TACHOMETER. THE DRIVER BEHIND ME (ANOTHER BMW 3 SERIES),TAILGATED ME. IT SCARED ME SO BAD, THAT I DID NOT SEE A DEEP POT HOLE IN THE ROAD SURFACE. I HIT IT SO HARD, THAT I SPUN AROUND AND ALL OF MY WHEELS WERE DAMAGED. I HAD ALL FOUR WHEELS REPAIRED AND TIRES AT A COST OF $2000.THE DAY BEFORE, I NOTICED THE SERVICE ENGINE SOON LIGHT WAS ON. OF COURSE, I WANT THIS CHECKED OUT.SO I SCANNED THE CAR. IT WAS DISPLAYING 000030 BMW/ OR FOR/ P CODE P0741 " TORQUE CONVERTER CLUTCH VALVE STUCK OFF .SO I WENT TO A BMW DEALER. EXPLAINED EVERYTHING. THEY SHOW ME THE CODES PULLED FROM THE CAR. THE CODE FOR THE TC CLUTCH VALVE NOT WORKING WAS SHOWN.(THEIR EQUIVALENT TO P0741) THEY TELL ME IT IS THE DISA VALVE.???? IS BMW TRYING TO COVER THIS UP?.DISA HAS ZERO TO DO WITH THE TORQUE CONVERTER. I SEE HOW MANY HAVE FAILED AND BMW DOES NOTHING? I COULD HAVE BEEN KILLED. THE CAR DID NOT RESPOND WITH MY REQUEST IN A MANNER THAT AFFECTED MY WELL BEING. IF THIS PROBLEM IS INVOLVED WITH MANY, MANY CLAIMS BECAUSE OF A PART THAT IS PROVEN TO BE DEFICIENT AS IT SOUNDS, I AM SURE IF INVESTIGATED YOU WILL FIND SOME INJURIES AND/OR DAMAGES AND DEATHS HAVE OCCURRED
