2012 Audi A4 Problems & Owner Complaints

Engine 16

“CAR HAS BEEN INTERMITTENTLY SHUTTING DOWN WHILE DRIVING. AND STARTING UP THE CAR HAS BECOME MORE AND MORE RANDOMLY JUSTIFIED. SOME TIMES IT STARTS UP RIGHT AWAY, SOME TIMES IT JUST TAKES A FEW CRANKS. DOESN'T MATTER IF IT'S WARM OR COLD ENGINE. I PULLED ECU CODE AND IT SAYS U0100 WHICH IS LOSS OF COMMUNICATION TO ECM. WELL THIS IS A SAFETY ISSUE BECAUSE I CAN BE DRIVING JUST FINE ON THE ROAD BUT ALL OF A SUDDEN IT JUST DECIDES TO QUIT CAUSE A HAVOC ON A BUSY TRAFFIC IN HOUSTON.”

“TAKATA RECALL: MY 2012 AUDI A4 WAS TOTALLED IN JULY 2014.

“THIS CAR HAS A MASSIVE OIL CONSUMPTION ISSUE. A WEEK AFTER HAVING AN OIL CHANGE THE LOW OIL LIGHT COMES ON AFTER APPROXIMATE 150 MILES OF DRIVING.
