Description of the Problem: The fuel pump housing on my 2016 Volkswagen Passat (1.8L TSI) developed visible cracks, which caused a persistent fuel vapor smell around the vehicle, especially after refueling. The failed component — the plastic fuel pump assembly manufactured by Continental — is available for inspection and has been photographed. Safety Risk: The cracks allowed gasoline vapors to escape, creating a clear fire hazard. I experienced headaches from the fumes while driving, and the smell was strongest when the vehicle was full of fuel. Vapors were most noticeable when the air circulator was turned off, suggesting that fumes were entering the cabin. Confirmed by Mechanic: A certified independent mechanic confirmed the cracks after removing the back seat and inspecting the fuel pump directly. The entire assembly was replaced, and the issue was resolved. Prior to this, a VW dealership misdiagnosed the problem as a bad gasket, quoting me over $1,300 for a repair that would not have addressed the actual issue. Inspection History: The vehicle was inspected by the VW dealership first, and later by the independent shop that completed the repair. No police or insurance involvement. Symptoms: No warning lights or messages appeared. The only symptoms were the strong fuel odor, especially when the tank was full, and inaccurate fuel gauge readings leading up to the diagnosis. Summary: This issue appears similar to other known failures involving Continental-manufactured fuel pump flanges that have led to VW recalls in other models. My concern is that this defect may extend beyond currently recalled vehicles and should be investigated further.

The fuel delivery system appears to have failed. Specifically, there is an active gasoline leak from a fuel line inside the cabin, near or under the rear seat. The source may be related to an unresolved recall involving the fuel rail detaching from the engine, which causes pressurized fuel leakage. The failed component is still present on the vehicle and available for inspection upon request. The back seat was removed by a mechanic who observed gasoline actively spewing into the cabin. This defect presents an extreme fire hazard. The constant gasoline fumes in the interior have caused me to suffer migraines, nausea, and dizziness while driving. My 13-year-old daughter, who has asthma, must ride with her head out of the window to breathe. My 2-year-old can no longer ride in the vehicle at all due to the fumes. I am a single mother with no other transportation. I fear that the car could ignite at any moment, especially with electrical systems running in the cabin. This defect is life-threatening. A certified independent mechanic removed the rear seat and confirmed that fuel was actively leaking into the interior of the car. The mechanic advised that the vehicle is unsafe to drive and poses a severe fire risk. I have photos and video available, and the mechanic is willing to provide a written statement upon request.Volkswagen dealerships have refused to inspect the vehicle or address the recall, even though the recall remains listed as active under the vehicle’s VIN. I have contacted multiple dealerships and Volkswagen corporate, and have been denied assistance. I have not contacted police or insurance yet, but I am preparing formal complaints.There were no warning lamps or dashboard alerts. The first symptom was a strong fuel odor in the interior, which began approximately 5-6 months ago. It progressively worsened over time. About one week ago, the smell became severe enough that it was unbearable to drive. This prompted the mechanic’s inspection, which revealed the

After several attempts to identify the cause of my vehicle's excessive oil consumption, white smoke out of tail pipe and illumination of my low oil and EPC lights, the VW dealership has diagnosed my vehicle with a failed air oil seperator/PCV stuck in the open position. During the times the EPC light illuminated, I had a loss of engine power which potentially could have led to engine shut off and caused an accident. I often drive on the highway with construction with my children so sudden engine shut off is a safety risk. On 12/18/20, I took my vehicle to the VW dealership for excessive oil consumption, low oil and EPC lights and white smoke out of tailpipe. The technician diagnosed and repaired a blown upper timing gasket. The problems persisted and I dropped off the vehicle at the dealership on 01/19/21. Dealership advised computer update was needed and was performed. Problems persisted and vehicle was dropped off on 01/30/21 and 03/15/21 for oil consumption tests and advised results were in 'acceptable' range for VW. After researching work history on my vehicle, I remembered I took it in while under warranty (under 36k miles) for fuel smell in cabin when using the heater. VW technicians checked fuel lines, injectors and fuel tank but found nothing wrong. After researching this topic on various VW blogs, I found the fuel smell in cabin was caused by failed PCV system in numerous cases. I believe my air oil seperator/PCV was faulty and began to fail while my vehicle was still under warranty. Further internet research revealed websites and blogs with numerous mentions of failed VW/ Audi PCV systems. I believe my vehicle may have been affected by a faulty part installed and has been overlooked by VW.

Like other volkswagen group models my car has exhibited a gasoline smell in the interior of the car. The gasoline smell occurs both when the car is at rest and in motion and at all temperatures. The gasoline level does not seem to effect the occurrence of the smell. The local dealer has been unable to diagnose this problem. I find this curious as other 2016 volkswagen models with the same engine have been recalled for this same issue.
