What owners reported
Source: NHTSA complaint databaseOwners of the 31 model years this bulletin names have filed 86 complaints with NHTSA since 2015. 35 of them name Electrical System — 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.
Vehicle malfunctioned and stopped in middle of highway with no warning. It forcefully braked to shutdown. Was able to restart car and drive away after a minute. Two days later it had emergency SOS warning on dashboard. Took vehicle in for diagnostic and repair. When pushing software update the module locked up and car would not start.

Common questions
Source: NHTSA, 49 CFR 579.5Is Audi TSB_2078077_2 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_2078077_2 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
