The fuel supply line for the high pressure fuel pump may become porous over time, resulting in a fuel leak.
A fuel leak in the presence of an ignition source can increase the risk of a fire.
What to do
Audi will notify owners, and dealers will replace the fuel line free of charge.
The recall is expected to begin August 21, 2018.
Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 20AV.
