The issue
On certain Audi 5000 turbo and 5000 Quattro, repeated `topping off' of the fuel tank after the gas station pump has stopped the fuel supply during refuelling, reduces the expansion space within the fuel tank. Consequent pressure conditions within the evaporative emission control system could result in fuel vapours being released into the engine compartment. Heat from the turbo exhaust system could ignite the vapours and cause an engine compartment fire with a risk of injury to the vehicle occupants. Correction: Vehicles will be fitted with a new vent valve and a new type charcoal filter vent hose. In addition, Quattro models will receive a redesigned fuel filler neck.
Description (français)
Sur certaines Audi 5000 turbo et 5000 Quattro, si on remplit le réservoir jusqu'au bouchon après le déclenchement du mécanisme de coupure de la pompe à essence, l'espace libre prévu pour la dilatation dans le réservoir devient trop limité. La pression résultante dans le circuit de récupération des vapeurs peut entraîner un dégagement de vapeurs dans le compartiment moteur. Celles-ci peuvent s'enflammer au contact de l'échappement du turbocompresseur et provoquer un incendie. Les occupants de la voiture risquent alors d'être blessés.
