On certain vehicles, aging of the plastic material in the fuel tank rollover valve, combined with bending stress from the aluminium ventilation line to the rollover valve nipple, may lead to cracking of the nipple. If this happens, a fuel leak may result. Fuel leakage, in the presence of an ignition source, could result in a vehicle fire. Correction: Dealers will reinforce the rollover valve nipple.
On certain Audi S6, A6 and A6 Allroad Quattro, contact between the left driver's side crash element and the headlight switch wiring harness could eventually result in an electrical short. Even though such an electrical short is not very likely, it could result, in a worst-case scenario, in a fire originating in the left dashboard area. Correction: Dealer will install a protective covering on the crash element and inspect the wiring harness for damage.
