There are 5 owner-reported fuel system complaints for the 2014 Audi A4in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The contact owns a 2014 Audi A4. The contact stated while at a stop sign and attempting to proceed, the vehicle stalled and failed to return to normal operation. The contact and her boyfriend shifted into neutral and pushed the vehicle to the side of the road for a while until the vehicle eventually restarted. The Electronic power control (EPC) warning light was illuminated. The vehicle was driven back to the residence where the boyfriend used a diagnostic scanner to diagnose the vehicle. The contact was informed that the fuel pump sensor needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was scanned a second time and it was determined that the fuel pump module needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The diagnostic scan tool was used again to diagnose the vehicle and it was determined that the fuel pressure regulator needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 98,000.
Driving on a two lane busy road, car started to jerk and shut down. Lost steering capability immediately, car veered toward ditch, stopped. Called 911 immediately because the road was busy and cars could not safely get around my stalled vehicle. I told 911 that I was exiting the vehicle for my safety. I could not restart the vehicle. There were no warning lamps or messages or symptoms alerting me to a problem UNTIL after the occurrence. I had no idea what was happening, and it was frightening. Never had this situation with any of my Audi's and I only have approximately 41,000 miles on it. After about 15 minutes a person stopped and was able to restart my vehicle (911) never got to me and I cautiously drove home. Called the dealer and had it serviced immediately. Diagnostics performed on it. It required a replacement of the fuel pump and fuel rail sensor. It found fuel pump control module to be shorting out. It seems that this type of issue should not be occurring on the vehicle with such low mileage.
ON SATURDAY 10/26/2019 AS I LEFT MY OFFICE TO HEAD HOME THAT DAY FROM WORK MY EPC LIGHT AND ENGINE MIL LIGHT IN MY DASHBOARD CAME ON AND THE CAR WOULD NOT START. I STARTED TO SMELL GAS FUMES IN THE CAR AND SMOKE COMING FROM THE BACK SEAT LIKE A FIRE HAD STARTED. I SHUT OFF THE CAR, GOT OUT AND OPENED ALL THE DOORS AND AS I APPROACHED THE RIGHT SIDE OF THE VEHICLE I SPOTTED LARGE AMOUNTS OF FUEL LEAKING FROM UNDERNEATH WHERE THE FUEL PUMP IS LOCATED. I CALLED MY AUTHORIZED MECHANIC AS HE HAS DEALT WITH MY VEHICLE BEFORE AND HE CAME AND DIAGNOSED THE VEHICLE, HOOKED IT UP TO HIS COMPUTER AND GAVE HIM A FEW ERROR CODES. 1 WAS FOR THE FUEL PUMP, ANOTHER FOR THE AFTER RUN COOLANT PUMP. HE INFORMED ME THAT THERE WAS A MALFUNCTION WITHIN THE ELECTRIC FUEL PUMP ITSELF THAT'S CAUSING THE ISSUE AND THAT'S WHY FUEL STARTED LEAKING ALL OVER THE FLOOR UNDERNEATH THE VEHICLE WHERE THE FUEL PUMP IS LOCATED. HE ALSO ALERTED ME TO A SERVICE BULLETIN THAT SHOWED UP ON HIS COMPUTER THAT SHOWED A RECALL FOR THE SAME FUEL PUMP ISSUES RELATED TO MY VEHICLE AS WELL AS SEVERAL OTHERS. WE IMMEDIATELY CALLED A TOW TRUCK TO GET IT BACK TO HIS SHOP. UPON FURTHER INSPECTION AFTER HE REMOVED THE REAR SEAT TO GET TO THE FUEL PUMP IT REVEALED EXACTLY WHAT HAD OCCURRED. THE FUEL PUMP AND THE ELECTRONIC CONNECTORS CONNECTED TO THE PUMP ALONG WITH THE SEAL HAD BURNT OUT CAUSING FUEL TO SPILL EVERYWHERE AND FLOOD THE ENTIRE UNIT AS WELL AS MY BACK SEAT WHERE A SMALL SPARK FROM THE IGNITION WHEN STARTED ALMOST CAUSED A SMALL FIRE UNDER THE SEAT WHICH COULD OF ERUPTED BIGGER. LUCKILY IT DID NOT EXPLODE OR GOT ANY WORST AND OUT OF CONTROL. THIS IS A SERIOUS SAFETY RISK AND NEEDS TO RECTIFIED IMMEDIATELY BEFORE MYSELF OR ANYONE ELSE GETS HURT. MY CAR HAS BEEN WELL MAINTAINED SINCE I PURCHASED IT IN 2015 AND JUST HIT A LITTLE OVER 50K MILES, NEVER MISSED AN OIL CHANGE, YEARLY INSPECTIONS AND TUNE UP.
BECAUSE OF THE ODOR OF GASOLINE FOR SEVERAL WEEKS, I HAD ASKED THE DEALER TO INVESTIGATE AND WHAT THE REASON WAS, IF ANY. HE CALLED TO TELL ME THE FUEL PUMP WAS LEAKING AND THAT I SHOULD REPLACE IT FOR SAFETY REASONS SUCH AS GASOLINE COMING IN CONTACT WITH THE EXHAUST MANIFOLD. THE PUMP WAS REPLACED BY THEM. A COPY OF THE RECEIPT HAS BEEN UPLOADED. THANK YOU.
I HAD RECEIVED A RECALL JUNE OF 2018. IT STATES THAT MY CAR CAN ESSENTIALLY START ON FIRE. I WENT ON THE AUDI WEBSITE AND FOUND OUT THEY ARE SERVICING THE VEHICALS RIGHT NOW FOR THE AFTER RUN COOLANT PUMP, BUT HOPE TO IN THE FALL. THIS BEING SAID; DO I JUST HAVE TO WAIT AND PRAY THAT MY CAR DOESN'T START ON FIRE OR ? THAT'S NOT SAFE, AND I DIDN'T PAY THOUSANDS OF DOLLARS TO HOPE MY CAR DOESN'T START ON FIRE TILL THE FALL.
