NHTSA Complaint #11440781 — 2005 VOLKSWAGEN PASSAT

Approximately back in June 2021, I noticed the smell of diesel fuel coming from the rear of the vehicle, noticed hours and days after the vehicle was parked. The smell is partially present from the interior in the trunk area, but mostly evident when standing near the vicinity of the fuel tank when outside of the vehicle. After driving the vehicle, I occasionally notice small puddles of diesel fuel (as evidenced by the oily texture and smell) coming from below the fuel tank. On occasion, I can also spot actual drops of diesel fuel on the lower car frame from underneath the vicinity of the fuel pump. These puddles usually evaporate or dissipate within an hour or two after appearing. Given that these puddles only appear after driving, and not after extended periods of the vehicle sitting in my driveway, I suspect that there is a leak in the fuel pump. A more recent VCDS scan of the ECU on 29 October 2021 results in a Gateway and Dashboard fault code in the fuel pump, which may or may not be related to the fuel pump leak. The fault code is 00476, relating to the fuel pump control module, indicating "no communication"; the code is marked as "static". This fault code may not be related to the underlying fuel leak, but since it relates to the fuel pump, I thought it would be worth mentioning. Last but not least, a recall notice was issued on the diesel fuel pump assembly that impacted the make and model of my vehicle, issued in December 2004, just a couple months before the manufacture date of my vehicle (February 2005). As a result of this cut-off date, my vehicle's VIN number was not included in the official recall notice (NHTSA # 04V586000); see: https://www.vindecoderz.com/EN/Volkswagen/PASSAT/2005/fuel%20system,%20diesel/recall/04V586000. Due to the commonality of my vehicle's components with the 2004 Volkswagen Passat TDI and close temporal proximity to the recall notice, I highly suspect that my vehicle's fuel pump is impacted by this latent recall.
