2011 Audi S4

GEARBOX MALFUNCTION WARNING AND THE TPMS MALFUNCTION CAME ON AT SAME TIME. CONTINUED TO DRIVE IN LIMP MODE FOR ABOUT 1 MILE AND THE CAR SHUT COMPLETELY OFF. START THE CAR BACK UP AND STILL SHOWING WARNINGS. GET IT HOME AND ATTEMPT TO PUT INTO REVERSE AND THE CAR WON'T ENGAGE. I JUST HAPPENED TO START THE CAR AGAIN AND ALL LIGHTS WERE GONE. CAR WENT INTO ALL GEARS, DROVE FINE, AND GOT IT TO THE DEALER. TWO HOURS LATER I GET IN TO GO TO THE STORE AND AS SOON AS I SHIFT INTO D, THE TPMS AND GEARBOX MALFUNCTION LIGHT FLASH UP TELLING ME I HAVE NO REVERSE AND I'M STILL GOOD TO DRIVE. SO I DECIDE TO DRIVE DOWN THE STREET AND SEE WHAT THE ISSUE IS. AS SOON AS THE CAR WENT TO SHIFT FROM 1ST TO 2ND IT SKIPPED, REVVED IN NEUTRAL FOR ABOUT 2 SECONDS THEN DROPPED HARD INTO 3RD GEAR. THE NEXT MORNING I WENT TO DRIVE THE CAR AND DROVE AROUND THE NEIGHBORHOOD WITH NO PROBLEM - NO ERROR MESSAGE, NO FAULTY SHIFTING, NO JERKING OR ANYTHING. SO I DECIDED TO RUN TO THE STORE ABOUT 4 MILES AWAY AND SEE HOW IT HELP UP. I MADE IT TO THE STORE AND HALFWAY BACK BEFORE BOOM - IT HAPPENED AGAIN. CAR WILL START IN 1ST GEAR FINE, WENT SHIFTING INTO 2ND IT SLIPS INTO NEUTRAL FOR ABOUT 2-3SEC THEN DROPS ABRUPTLY INTO 3RD, WHEN YOU HAVE ENOUGH SPEED IT DOES THE SAME THING TRYING TO SHIFT INTO 4TH - SKIPS AND DROPS INTO 5TH, SAME THING INTO 6TH - SLIPS OUT OF 5TH AND DROPS HARD INTO 7TH. SLOWING DOWN WAS NOT A HUGE PROBLEM AS LONG AS YOU HAVE PLENTY OF ROOM TO TAKE IT EASY. IF YOU SLOWED TO FAST THE GEARS WOULDN'T KEEP UP AND IT WOULD JERK VERY HARD. THIS IS A SERIOUS MATTER SINCE IT IS A SYSTEM FACTORY FAILURE WITH THE DSG UNIT SIMPLE AS THAT. REASON WHY I AM CONTACTING THIS AGENCY AS THE CAR SHUT OFF ON ME WHILE YOU WERE DRIVING IT IN THE MIDDLE OF THE HIGHWAY AND I COULD HAVE BEEN HIT/KILLED THE FIRST TIME IT HAPPENED.
