Audi A6 fuel smell problems

Filed Dec 30, 2025 · Fuel system · NY

I own a 2016 Audi A6 3.0T. After filling the fuel tank completely, the vehicle only traveled approximately 190–200 miles before the fuel gauge indicated empty. This represents a sudden and significant loss of fuel range compared to normal operation. There are no warning lights, check engine lights, fuel smells, visible leaks, rough idle, or abnormal noises. The vehicle operates normally otherwise. The issue appears to involve excessive fuel consumption or incorrect fuel management without any driver warning. This condition poses a potential safety risk because the vehicle may unexpectedly run out of fuel while driving, which could result in loss of power in traffic or on highways, increasing the risk of an accident. The issue has been observed repeatedly after refueling. At the time of this report, the vehicle has not yet been inspected by a dealer or independent repair facility, but diagnostic evaluation is planned. Based on owner research and symptoms, the issue may be related to a fuel system, engine management, or emissions-related component malfunction that does not trigger a warning indicator. No prior warning messages or lamps were displayed before or during the occurrence.

The contact owns a 2012 Audi A6. The contact stated while pulling out of the driveway, he smelled an abnormal fuel odor. The contact stated that the fuel odor became stronger while driving 65 MPH. There was no warning light illuminated. The contact stated that he pulled into a parking lot and opened the hood. The contact stated that he noticed that the fuel odor was coming from the engine. The vehicle was towed to an independent mechanic, where the check engine warning light illuminated. The mechanic determined that the check engine warning light had illuminated due to low pressure on the fuel rail, and the contact was informed that the supercharger needed to be removed for a more thorough inspection of the vehicle. The dealer was notified of the failure and informed the contact that the VIN was not included in a recall. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in the federal safety agency Campaign Number: 15V019000 (Fuel System, Gasoline).

I have recently purchased my 2014 Audi A6 in Honolulu at JN Autogroup. After just a couple days of driving the vehicle I have noticed that the car started to smell like gas in and out of the vehicle. The smell is very potent and very sensible throughout every second of driving and I am reporting this because this could be very hazardous and I may not know if it could catch on fire with the amount of fumes that is lingering around. To the point where as I am driving it is making me dizzy. I have researched about issues for these cars with the same year, make and model and I have read that there was a recall on the fuel line leak but i don’t know why my car wasn’t included in this recall base of the data I have pulled up on the Audi recall center. I’m not sure if it has been recalled but the problem for sure wasn’t solved with my vehicle. On the other hand, I have also noticed that the reverse camera on this vehicle goes for a split second on the dash whenever in reverse then suddenly blacks out the entire screen. I am thinking that the wiring or some kind of harness that operates the reverse camera is not done properly by the factory that causes malfunctions within the system. In conclusion, these are two of the reasons why I am completing this incident report because I feel that these are two hazardous features that is important for not just myself but the community and people that surrounds me whenever I am on the road behind the wheel. It is important for this to be resolved because the company of this vehicle advertises all these features and sells this product but there is an issue with the product and I want it to be looked upon and not swept under the rug because I am not only speaking for myself but for the many thousands and thousands of these car owners that is on the road today who are having the same issue as I do. I’d appreciate your service if this can be fixed, thank you!

The gas tank or components of the tank are leaking gas when more than a small amount of gas is put into the tank. Gas leaks all over the ground from the tank and the cabin fills with gas fumes. My 18 son has been driving this car and I will not allow him or anyone else to drive the car now. After reading online that many people have this same problem, I am shocked that this is not a recall when it could be potentially life threatening and that audi wants to charge 3k to lower the tank and repair.

I was driving my vehicle & noticed a fuel smell. When I got to my destination shortly down the road (~1 mile) I inspected my engine for the source of the smell & found fuel leaking down the front of my engine from under the supercharger. After disassembling the top of the engine I found the injector supports to be the old recalled parts (verified with engraved part numbers). I then called the audi dealer that supposedly performed the recall and explained the situation. They were very dismissive & advised me to bring the vehicle in. After a few days (4-7) they advised me they would be having a representative from audi come look at it. I attempted to contact audi multiple times for a loaner vehicle with no response. After multiple days of reaching out, I showed up to the dealer & was given a loaner vehicle due to the kindness of another advisor. The recall: 24ap fuel injection system leak. In the audi notification to the federal safety agency they specifically call out the injector support being revised under "description of remedy" stating " implementation of reinforced fuel rail retaining bracket" & received an updated part number which changed from 06d133036h to 06d133036k. I am worried more people could have this potentially fatal issue due to the lack of craftsmanship shown at that dealer. The issue could be swiftly covered up if the customer does not have the mechanical inclination to verify correct work is being performed on their vehicle.

In the summer months, my 2014 audi a6 develops fuel-like fumes filling the cabin and trunk. The fumes become more intense/pronounced when I accelerate from a stop or when moving through traffic. Several times in 2019, my audi hesitated then stopped twice in traffic. Once on a city road and the other time on the left lane of a highway. Audi service diagnosed a gas pump issue. However, a replacement gas pump did not fully prevent gas fumes from developing in the car. I believe this is related to the federal safety agency campaign id 17v781000/volkswagen 20ar. But, I've been told otherwise from the dealership and your site.

I have a fuel leakage on the lower right side of my vehicle and as soon as I park the vehicle I can feel the fuel smell all around my vehicle. I have given my vehicle to authorized audi dealer (bell audi,edison) and they never said anything about the recall going on audi vehicles

Upon starting my vehicle I noticed extended cranking. Upon driving the vehicle I noticed a fuel odor, initially I thought it was the older vehicle driving in front of me. After driving approximately 4 miles I realized it was my vehicle. I then drove my vehicle back to my house, and had it towed to audi of albany due to recalls that were open. Upon inspection they performed recalls, but informed me the recall for the engine fuel rails was performed june 2015. They then told me they needed to charge labor to inspect the issue, to which point I told them I am an ase master mechanic, and I will figure the issue out myself. I then had the vehicle towed to my garage, where I took it apart following the recall provided on your website. Upon inspection I verified that the injector supports (p/n 06d133036k) listed in the recall (code 24ap) were never replaced. The injector supports I removed from my vehicle are (p/n 06d133036h). Audi has had my vehicle now from 21nov2018 until the present. They will not verify that those parts were supposed to be replaced during the recall, and also if any other parts were never replaced. They have contacted me and told me my fuel injector failed causing the fuel leak, and everything will be covered. I believe my injector failed (if that is the truth) due to the non replaced injector supports. The incorrect geometry over time would cause stress on the injector, and for it to crack. I also question if any seals were truthfully replaced, or if the recall was done at all. I also fear that this issue may have occurred to others who had the recall performed there (langan audi), and are not mechanically inclined enough to disassemble there engine and fuel systems. This problem could have caused a fiery death for me and my family in the car if I wasn't inclined enough to realize the problem is my car and not others around me.
