OWNER WAS NOTIFIED OF SAFETY RECALL 19N4 - DISCONNECT ELECTRIC COOLANT PUMP AND HAD THE RECALL SERVICE PERFORMED ON 29 DEC 2018. OWNER WAS INFORMED THAT AN ADDITIONAL SAFETY RECALL (19O2) WILL REPLACE THE COOLANT PUMP WITH A NEW ONE. ON 04 MARCH 2019, WE CALLED AUDI USA AND WERE TOLD THAT THE REPLACEMENT WAS NOT YET AVAILABLE. THE COOLANT PUMP ALSO AIDS IN PROVIDING ADDITIONAL CABIN HEAT WHICH IS IMPORTANT DURING THE WINTER MONTHS FOR THE COMFORT AND SAFETY OF OCCUPANTS IN THE VEHICLE. DUE TO THE PUMP BEING DISCONNECTED, THE CABIN HAS BEEN VERY SLOW TO WARN, INCLUDING THE WINDOW DEFROSTERS. THIS PRESENTS AN EXTREME SAFETY ISSUE ESPECIALLY DURING THE WINTER MONTHS. IT ALSO PRESENTS A POSSIBLE DAMAGE ISSUE SINCE THE AFTER COOLANT PUMP IS USED TO ALLEVIATE HEAT FROM THE TURBOCHARGER. AUDI USA STATED ON 04 MARCH 2019 THAT THE NEW COOLANT PUMPS WILL BE AVAILABLE SOMETIME IN THE FUTURE.

IM AN ACTIVE DUTY MILITARY SERVICE MEMBER STATIONED OVERSEAS IN SOUTH KOREA. I CURRENTLY OWN A 2015 AUDI A6. I WAS RECENTLY NOTIFIED THAT MY VEHICLE HAD 2 RECALLS PLACED, SPECIFICALLY ON THE ELECTRIC COOLANT PUMP AND ON THE PASSENGER OCCUPANT DETECTION SYSTEM (PODS). I VISITED MY LOCAL AUDI DEALERSHIP IN KOREA AND THE AUDI STAFF SAID THAT THEY CANNOT FIX OR REPAIR THE ISSUE SINCE IT IS A U.S. SPECIFIC RECALL. I CALLED THE U.S. AUDI SERVICE DESK AND THEY ALSO SAID THAT THEY CANNOT HELP WITH THE ISSUE AND TOLD ME TO CHECK WITH NHTSA. I FULLY UNDERSTAND THE LIMITATIONS IN THIS MATTER BUT I DO WANT TO APPEAL THAT THERE ARE SEVERAL MILITARY MEMBERS IN THE SAME SITUATION. AS A SERVICE MEMBER, HUSBAND, AND A FATHER, I AM DEEPLY CONCERNED ABOUT THE SAFETY OF MY CAR. I SINCERELY WANTED TO REACH OUT AND SEE IF THERE IS ANY POSSIBLE WAY TO RESOLVE THIS ISSUE OVERSEAS. YOUR THOUGHTS IN THIS MATTER WILL BE DEEPLY APPRECIATED, THANK YOU VERY MUCH FOR YOUR TIME. *TR
