Filed Jul 11, 2017 · Fuel system · 108,789 miles · NC

Check engine light on, vehicle will not pass emissions testing. Audi determined that it was due to a fuel leak from a crack in the passenger side rear rollover valve. Vehicle had been recalled in past for similar issue (performed). Tank has 4 rollover valves, only one (front driver) included in prior recall. Initial quoted $3,300 to replace tank. Audi offered to pay for replacement tank with the exception of ~$600 (repair order attached). Repair completed on 2/23/2017, car passes state inspection. As you can see by the "staining" in the attached photo, the leak was significant dealer then calls to say that car needs to be returned to perform prior recall on the newly installed tank. Recall to be performed on only the one rollover valve (driver front) that can be accessed with out removing fuel tank. Not the valve that was leaking and necessitated the replacement. I requested that audi perform recall on all 4 rollover valves as they installed a knowingly defective part and the risk of another crack/leak exists. Dealer says audi refuses. I have made several calls to both dealer and audi with no response from audi beyond a conversation with customer service. Check engine light back on 5/08/2017. Emailed dealer on 5/11/2017 (attached pdf) with my request (again), and have received no contact from audi. Returning car to dealer for recall on the one rollover valve on 7/12/17. Audi is putting this car back on the road with the strong potential of a fuel leak.

2003 a6 quattro avant 3.0 car ran fine driving to work. When leaving at end of day, started car and it ran very rough I decided to reverse back into parking space and at that point noted smoke coming from under hood (car had run for approximately 20 seconds). Turned off engine, opened hood, and found the drivers side rear coil pack burning. Extinguished flame using a baseball cap to smother it out. Coil pack continued to smoke and reignite due to burning inside coil pack. Jammed screwdriver into pack to root out flame. Had car towed to audi dealer - awaiting repair. There is an active recall campaign for bad coil packs (28f2 / j1) - recall states check engine light may come on and car will run rough, further recommends returing vehicle to dealer at that time. There is apparently two ways the pack can fail - a fault on the high voltage end just bypasses the spark to the engine block causing a misfire. A fault at the low voltage end results in a short and most likely a fire. This potential for fire is understated by audi and shoud be clearly identified in the recall campaign to ensure the right urgency is placed on this issue. The fact is, I was able to react and extiguish the fire, had this occured in other circumstances the car would most likely have completely burned.

Aoa has failed to take responsibility for a safety related defect in my audi a6 fuel system. Given a the federal safety agency product safety gas storage tank recall, I believe aoa are liable for this safety related defect. On june 26th, 2009 hoffman audi, east hartford ct, service manager jim orman orally informed me that aoa will take no further action in this matter, the reasons provided were: 1) recall was on other side of the tank - this particular valve was not part of the recall and they've seen only a few others with issues. ?there was no possible way this could occur during the recall repair.? 2) fuel tank was out of 4 year, 50000 mile warranty. 3) aoa disregards the unsafe condition caused by fuel vapor/fluid leaks resulting from the defective/worn out valve. In discussion it was referenced that ?there were only four other instances of this problem? And cited age of the vehicle. I was told that after reviewing images of my claim, the final decision was made by karl krug, new england regional service manager aoa. Background: in late 2008 I was made aware of a safety recall regarding the potential for fuel tank leakage resulting from cracked nipples on this plastic gas storage tank. A reinforcement repair was performed on my vehicle in december 2008 (the federal safety agency campaign id number:08v157000). Roughly one month later the check engine light illuminated and the diagnostic fault code related to the tank ventilation system was identified. Last week I isolated the p0456 16840 tank ventilation system pinhole leak code to the fuel tank. Given the complexity of the ventilation system in the fuel tank area, I decided to get the system tested by a dealer. A cracked valve nipple atop the gas storage tank was identified by a volkswagen service center. I have filed a complaint with the ct attorney general and asked they forward to the appropriate state and federal agencies for further investigation.

2003 audi a6 had problems with the engine light, smoking, and little to no acceleration. Consumer states that after a few repairs the problem is not solved and wants to be refunded her money. *nj the dealer informed the consumer the #1 and #3 coil needed to be replaced. The consumer drove less than a mile and the check engine light came back on blinking and the vehicle was moving very hard. When the consumer returned to the dealer, they diagnosed the vehicle again, the consumer was told the #6 ignition coil needed to be replaced. Because no one ever test drove the vehicle when it was suppose to be fixed the first time, the dealer replaced the #6 coil for free. The consumer left the dealership again only to have the engine light come again, but it wasn't blinking. The dealer diagnosed the failure and stated it was the torque converter clutch circuit performance.

I was driving my 2003 audi a6 3.0 quattro on thursday 04/03/2008 around 10:30pm. I was traveling 25mph on sylvan avenue in englewood cliffs, nj the check engine light illuminated on my dash board and started flashing, I immediately pulled over to the side of the road to diagnose the problem, when I pulled over I saw smoke coming out from under the hood of my car. I immediately turned of the vehicle and popped the hood to see what was going on... I popped the hood to find the ignition coil on the third cylinder (back left cylinder) had started on fire with about 12inches of flames. Thank god this all happened I about 30 seconds and I was able to get the fire out, otherwise the whole car would have burned to the ground. If I was stuck in traffic or on the highway this car would have most definitely burned to the ground. I feel very lucky my two year old daughter was not in the car with me. Nevertheless, the ignition coil is completely melted as well as the wiring harness. I always have done all the manufacturer recommendations on the vehicle and the car was just at the dealer service center on 04/01/2008 for maintenance, I had them look over the whole car and they said everything was fine. After speaking to service technicians at audi I have found this to be a commonly recurring problem with their ignition coils, specifically pertaining to the third cylinder, they claim it overheats because the design is to close to the catalytic converter. All I know is something should be done, I have pictures of the damage where you can clearly see some type of electrical malfunction that I would be more then willing to share. Please someone do something before a life is lost from this manufacturer error.!!!

Faulty ignition coils (so far 3 out of 6 cylinders went bad). On three occasions after starting and putting the car into the gear, shaking ensued and the "check engine" light turned on. The car had to be towed each time to the dealer where the faulty parts were replaced.
