If you are the owner of a 2017-2018 Audi R8 Spyder or R8 Coupe, you may be receiving a manufacturer defect notice for the power train of your vehicle. According to the defect report filed with the NHTSA, during extreme maneuvers the transmission fluid could expand and foam up beyond the expansion volume in the gearbox, causing the transmission fluid to leak out of the gearbox ventilation hose. The fluid could contact hot engine parts, causing smoke and a possible fire.
Dealers will correct the problem by adding a double ventilation hose that has a higher oil expansion volume. Volkswagen’s number for this recall is 34J1 and the NHTSA campaign number is 18V-639.
