What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 30 complaints with NHTSA since 2015. 1 of them name Visibility/Wiper — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
If the vehicle is left outside in the sun, the backup camera and/or side cameras stop working. It happens very often, but it’s unpredictable. Because if very bad read visibility, reversing in this car is impossible without the backup camera

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2078654_1 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the TSB_2078654_1 repair free?
