Fuel system, gasoline: deliveryReported April 7, 2008 · 412,000 vehicles affected
What is wrong
Volkswagen is recalling 412,000 my 1999-2005 passat (5th generation) vehicles equipped with automatic transmissions and produced after june 14, 1999. These vehicles may have an underbody heat shield that can become damaged. In addition, affected vehicles with automatic or manual transmissions may have a fuel line (1.8t engines only) or fuel tank ventilation valve (4motion/all wheel drive only) that can leak due to fracture.
Risk
A heat shield that may contact the exhaust system can result in a vehicle fire. In addition, a fuel leak from a fuel line or fuel tank ventilation valve, in the presence of an ignition source, can lead to a vehicle fire.
Remedy
Dealers will install additional underbody heat shields on vehicles with automatic transmissions to cover the possibly damaged areas and flash all 1.8t engines with a precautionary software update. Dealers will also inspect and adjust the fuel line routing on 1.8t vehicles and the fuel tank ventilation valve on 4motion/all wheel drive vehicles, and replace components if necessary free of charge. The recall began on june 13, 2008. Owners may contact volkswagen at 1‑800‑822‑8987.

Defect investigations

Engine Compartment FireOpened January 26, 2011, closed February 17, 2012

In July 2010, the Agency opened PE10-027 to investigate allegations of coil on plug (COP) ignition coil fires in MY2002-2003 VW Passat vehicles.The investigation was upgraded in January 2011 to include all MY2001-2007 4-cylinder VW Passat, gasoline, turbo-charged vehicles.Based on the analysis of VW's response, and including ODI's consumer complaints, ODI has since identified 135 unique engine fire reports attributable to the COP coils.After further review of the details as contained in each report, ODI determined that 43 of the 135 fire reports were actual fire/flame incidents, 83 fire reports were thermal events (smoke, spark, heat or wire melt), and another 9 fire reports were undetermined in severity due to the lack of information.These COP coil fires were characterized as initiated from within the COP coil circuit located at the top of the engine block and below the plastic engine cover.The fires observed were contained in the engine compartment and did not reach into the passenger compartment in contrast to those caused by an overheated catalytic converter examined in ODI?s investigation in 2007 and 2008.There were no reports of crashes or personal injury in this examination.A safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist.The agency will monitor this issue and reserves the right to take further action if warranted by the circumstancesSee the Closing Report for additional details.

Fuel tank leakOpened January 31, 2008, closed May 30, 2008

Volkswagen (vw) is recalling certain vw passat 4motion and audi a6 quattro and allroad quattro all-wheel drive passenger cars.vw vehicles subject to recall were manufactured from november 22, 2000 through may 31, 2005 and audi vehicles subject to recall were manufactured from june 2, 2001 to june 1, 2005.the federal safety agency recall number for the vw vehicles is 08v‑156 (vw also is correcting defects related to heat shield and fuel line hazards for these vehicles and for 1999-2000 passats in this recall action.)the federal safety agency recall number for the audi vehicles is 08v‑157.since 2006, odi has received 17 complaints of fuel leaking from the subject vehicles' fuel tanks.the 400 complaints shown above may include duplicate reports to odi and the manufacturer. While the consequence (fuel leaks from the top of the tank) is similar for both the passat and audi subject vehicles, differences in design and construction require a different remedy for each vehicle.on the passats, the ventilation line could have been installed improperly with tension and with an incorrectly positioned cable tie.the tension could cause cracked or broken nipples on the fuel tank rollover valve.on the audi vehicles, a material change (effective june 2, 2001) with different aging characteristics used for the rollover valve and the use of an inflexible aluminum ventilation line could cause cracking of the nipple on the rollover valve.vw is recalling all vehicles subject to these defects.it will inspect passats to ensure that the vent line is tension free and correct the installation if tension is found.if a crack or fuel leak is found, vw will replace the fuel tank.audi will repair all subject vehicles by reinforcing the fuel tank rollover valve with an epoxy adhesive.this investigation is closed.

Filed Aug 1, 2025 · Fuel system · ME

A fuel leak has developed from the top side of the fuel tank on the drivers side of me vehicle. A fuel leak in this manner is a serious critical and immediate safety risk. Recall 08V156000 was 'performed' on my vehicle back in 2008 but the exact same fuel system safety defect has returned. VW acknowledges the recall and claims it was completed while only an inspection to check for fuel leaks was performed at the time. VW Care and my local dealership refuse to address the ongoing issue. This poses a continued fire risk, and I am now being told to pay out of pocket for a known safety recall that clearly failed to remedy the original defect.

There was a recall reported by the manufacturer, Volkswagenm in 2008. There were multiple Fuel System issues: A Heat Shield that may contact the exhaust system and result in a vehicle fire; a fuel leak from a fuel line or fuel tank ventilation valve, in the presence of an ignition source, can lead to a vehicle fire. In 2008, my car was inspected and the recall was deemed "complete." However, the car was only 4 years old at the time and no repairs were made. Only a visual inspection was done. I bought the car used 6 years ago, and it has been diagnosed as having a defective fuel tank ventilation valve. VW should pay for the parts and labor to have this fixed because it was never fixed. I've been told there's no statue of limitations on recalls. VW claims that because the recall was deemed "Complete" that they "fixed" the issue but they didn't.

When you fill up the fuel tank it leaks it leaks a quarter of a tank of fuel roughly 4 to 5 gallons of fuel drip out there's a factory recall on this issue I took it to the volkswagen dealer paid money to have them inspect it and they said yes it's leaking at the factory recall I've had an independent dealer confirm that! Volkswagen will not do anything due to what they claim a remedy was done by moving fuel lines 10 years ago, obviously it was not or I would not have 4 gallons of fuel spill in my driveway vehicle is basically in operable and they want $3000 to put a new fuel tank in when it's a factory recall which never expires I have talk to the volkswagen rep and the only thing I have found in forums is do you have to go to volts wagon of america and fight them and this is ridiculous when they know they have an issue!! To drive this vehicle we never fill it over a half a tank of fuel so we do not leak fuel or explode while we're driving hopefully please help in anyway you can thank you

A coil for heated seats has melted a hole in the driver's side seat. This caused pain and confusion while driving on the highway. The seat now has an ugly melted hole in it.

While driving on a highway, the driver seat suddenly overheated (the seat warmer was turned on). It started with a burning smell. Excessive heat burned my leg a bit (some skin redness), before I realized what is happening and turned the seat warmer off. The seat leather now appears stiff and wrinkled (not soft and smooth like the rest of the leather) in the area where I felt the heat.

While driving the car at highway speeds it stalls and the epc light comes on. This has happened many times while merging with other traffic and can be very dangerous. I have spent well over $1000 trying to get this problem fixed, and the problem still remains. Even the vw dealership dose not have an answer.

Strong odor of fuel in the car regardless of being parked or moving. Noticed puddle of gas on the ground under the fuel tank. Fuel was dripping down off the fuel tank and the heat shields. Followed drip to the rollover valve nipple which is attached to the gas tank.
