2014 Audi Q5 Fuel system Problems

Post fix EDR cooler failure causing coolant fluid loss " enough complaints =pressure on Audi Reference EA189 emissions fix Subject: Goodwill Assistance Request – 2014 Q5 TDI EGR Cooler – VIN [XXX] Audi Customer Experience Team, I am writing to request goodwill assistance for my 2014 Audi Q5 TDI, VIN [XXX] , with 105,000 miles. Vehicle Issue The car is losing engine coolant with no external leaks. Symptoms are consistent with a failed EGR cooler: low coolant warnings every few weeks, white smoke on cold starts, and no puddles or visible leaks. This is a documented failure mode on the 3.0L TDI V6 engine, especially after the emissions modification. Warranty Background - Original in-service date: [XXX] - Emissions modification completed: 2018 - Current mileage: 105,000 I understand the EGR cooler is a covered component under the TDI Extended Emissions Warranty as an emissions-related part. While the 10-year time provision from the in-service date expired [XXX], I am well under the 120,000-mile limit. The 4 years/48k miles from the 2018 modification also places the failure directly within the spirit of the extended coverage. Basis for Goodwill Request The EPA-approved emissions modification increased EGR duty cycles and thermal stress on the cooler. This failure is a direct consequence of that modification. Repair quotes from Audi dealers are $1,200-$2,000 due to the labor involved to access the cooler in the V of the engine. The vehicle has been maintained with VW 507.00 specification oil and has no aftermarket modifications. I intend to keep the vehicle long-term if repaired. Request I respectfully request Audi cover the diagnosis and replacement of the EGR cooler under goodwill. I am happy to have the work performed at an authorized Audi dealer in Houston. I appreciate your consideration and can provide service records or additional photos if needed. I can be reached at [XXX] or this email. Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)

The car has a known "oil consumption issue" that has led to engine failure that Audi has failed to take responsibility for. This is a 2104 Audi Q5. The car is in San Francisco and available for inspection. The car vibrates and can't be safely driven at highway speeds, if the engine suddenly lost power on the highway it could be a major safety issue for the driver and other drivers. The dealer has reproduced the issue and diagnosed it as needing new Pistons and Rings at 99,000 miles (but it has had this issue since in the 60,000 mile range, they just said keep adding oil). It has not been inspected by police or insurance representatives, just the dealers. I'm sure some warning lights came on, but could not say which ones or when.

Unknown, but can assure the gas tanks has cracks and leaking gas, along with the smell of gas inside the car and outside the car. Called Audi and spoke with a rep but they dont want to acknowledge the recall which was issued for the vehicle. I made an appointment with Audi New Orleans, but the earliest appointment to get the vehicle check is August 28th, 2023. I have to go to work and the car can possibly catch a fire to the tank actually leaking. This is extremely dangerous and life threating. I definetly need help because let Audi tell it they dont see a recall at all for my vehicle.

I am writing about an incident that happened to my wife while she was driving my car from Los Angeles, CA to Phoenix, AZ on June 16, 2021. My wife was driving the Audi Q5 at approximately 75mph and 125 miles west of Phoenix (near the CA/AZ border) when the car suddenly loss power. She stepped on the gas and noticed the speed gradually dropping. Fortunately, she had the presence of mind and barely had enough time to pull over to the shoulder. It was at this point that she called to tell me that the car would no longer start and the “check engine” and “EPC” light indicators were illuminated. This occurred at approximately 12:30 noon during a severe heatwave where the outside temperature was 117 degrees. I asked her to wait for 10 minutes to try to restart the car; the car would not restart. She called AAA Towing and was told the wait would be over one hour because of the rural location (Quartzsite, AZ). She ended up waiting a little over 3 hours in her car, without air conditioning, in 117 degrees for a tow truck driver to arrive. The car was towed to her sister’s house in Goodyear, AZ at a cost of $673. The next day, she had the car towed to the Audi Dealership in Peoria, AZ where it was diagnosed the car had suffered a fuel vapor lock due to the heat. The car has less than 28,000 miles on the odometer when the incident happened. Audi Peoria kept the car for a couple of days because the parts had to be ordered from Los Angeles. Ultimately, the repair bill from the dealership came to $1,983. I felt helpless and scared for my wife that I was not able to assist her as I was 3 hours away. What if my wife (or another driver) was unable to pull over to the side of the road? The chances of an accident are dramatically increased if the vehicle was stuck on the highway. As you can imagine, my wife has been traumatized by this incident and we are both fearful that this incident can happen again. Therefore, we request that NHTSA investigate this incident.

"FUEL PUMP" WHILE DRIVING HOME AFTER A ROAD TRIP ON THE HIGHWAY (IN THE LEFT FAST LANE) MY CAR SUDDENLY LOST POWER AND WOULD NOT ACCELERATE WHEN PRESSING ON THE ACCELERATOR. THE "ECP" WARNING LIGHT CAME ON AND I HAD TO EASE THE CAR TO A STOP ON THE LEFT SHOULDER. AFTER ABOUT 5+ MINUTES, I WAS ABLE TO START THE CAR AGAIN AND MOVE IT OVER TO THE RIGHT-HAND LANE WHEN THE CAR STUTTERED AND SHUT OFF AGAIN. THIS TIME I WAS ON THE RIGHT SHOULDER. AFTER ANOTHER FEW MINUTES, I WAS ABLE TO START THE CAR AGAIN AND CALLED AHEAD TO TAKE IT IN THE NEAREST AUDI DEALERSHIP (IN THE TOWN I WAS RETURNING HOME FROM). THE CAR HAD SEEMED A LITTLE HESITANT TO START. THE NEXT DAY (JUST BEFORE CLOSING), THAT AUDI DEALERSHIP'S DIAGNOSTIC TESTS DETERMINED THE ERROR CODE TO BE '2043758/8 PUNCH 2 & 3' WHICH REQUIRED REPLACEMENT OF THE FUEL PUMP. FOUR PARTS NEEDED: FUEL PUMP, CAP, WASHER AND 'REPAIR SET'. SINCE THIS DEALERSHIP COULDN'T EXPLAIN WHAT THE 'REPAIR SET' WAS NEEDED FOR - THE MOST EXPENSIVE PART - I CALLED OTHER AUDI DEALERSHIPS AND SEARCHED THE INTERNET FOR INFORMATION. NO OTHER SOURCE MENTIONED A 'REPAIR SET'. ALSO, ALL BUT ONE OTHER PARTS DEPARTMENT SAID THAT THE FUEL PUMP PART WAS BACKORDERED BY 1-2 WEEKS DUE TO MANY RECENT ISSUES WITH THE THIS PART. SINCE IT SEEMED THAT I WAS BEING TAKEN ADVANTAGE OF BY THAT FIRST DEALERSHIP, I PURCHASED THE 3 PARTS (PUMP, CAP & WASHER) AT THE ONLY AUDI DEALERSHIP THAT SEEMED TO HAVE THE PUMP (ABOUT AN HOUR AWAY FROM MY HOME TOWN) AND MADE A SERVICE APPOINTMENT AT ANOTHER DEALERSHIP NEAR THE TOWN I WAS VISITING. A CONVOLUTED PROCESS TO GET MY Q5 FIXED BUT DUE TO THE NUMBER OF REPORTED ISSUES WITH THE FUEL PUMP ACCORDING TO THE AUDI MECHANIC, THERE IS A PROBLEM WITH THE AUDI FUEL PUMP IN ADDITION TO FUEL PUMP FLANGE RECALL.

FUEL TANK LEAK. WENT FOR A NORMAL UNEVENTFUL DRIVE FROM HOWARD COUNTY MARYLAND TO VIRGINIA SUBURBS AND CAME HOME BACK AND PARKED IN THE GARAGE ON FRIDAY THE 13TH!. WOKE UP IN THE MORNING TO A GARAGE THAT SMELLED VERY HEAVILY LIKE GAS. LOOKED BELOW THE AUDI Q5 AND SAW A SMALL PUDDLE OF GAS. PARKED THE CAR OUTSIDE THE GARAGE AND CALLED THE DEALERSHIP. THEY ADVISED THAT THIS COULD BE A SAFETY HAZARD AND ASKED TO CALL AUDI ROADSIDE ASSISTANCE FOR A TOW TO THE DEALERSHIP. AUDI ROADSIDE ASSISTANCE ASKED ME TO CALL THE LOCAL FIRE DEPARTMENT TO MAKE SURE IT IS NOT A FIRE HAZARD. THE VEHICLE WAS THEN TOWED AFTER THE LOCAL FIRE DEPT. MADE SURE THIS IS NOT A FIRE HAZARD WHILE BEING TOWED. THE DEALERSHIP CALLED ME TODAY (MONDAY THE 16TH OF JULY 2014) TO TELL ME THAT THE GAS TANK WAS HIT BY SOME ROAD DEBRIS AND ALSO MENTIONED THAT THERE ARE SOME SCRATCHES IN THE FUEL TANK AND WAS NOT SURE WHY THE LEAK IS OCCURRING. EVEN THOUGH THE BRAND NEW Q5 IS JUST 2 WEEKS OLD, THE REPAIRS WILL NOT BE COVERED UNDER WARRANTY AND ITS APPROX. $5,000 TO FIX THE ISSUE. I HAVE CALLED AUDI CUSTOMER SERVICE AND WAITING TO HEAR FROM THEM AT THIS TIME. I'M ALSO FILING THE COMPLAINT HERE SINCE THIS ISSUE SEEMS LIKE A SIGNIFICANT SAFETY CONCERN. HOW COULD A LEISURELY UNEVENTFUL DRIVE IN A BRAND NEW SUV ON THE FREEWAY LEAD TO THE FUEL TANK BEING RUPTURED OR CRACKED FROM ROAD DEBRIS! THIS JUST DOES NOT SEEM RIGHT. SINCE IT WAS PARKED OVERNIGHT IN A CLOSED GARAGE I WAS ABLE TO FIND THE ISSUE. I'M WORRIED THAT THERE MAY BE OTHERS PARKED IN THE ROAD THAT MAY NOT FIND THE ISSUE AND COULD CAUSE A FIRE WHILE ON THE MOVE OR IT COULD BURN DOWN THE HOUSE IF PARKED IN A CLOSED GARAGE FOR EXTENDED PERIOD OF TIME. *TR
