2019 Audi S4 recalls

Recall 21V-874: Air Bags, Seats

Reported Nov 10, 2021 · 208,332 vehicles affected · Volkswagen Group of America, Inc.

Problem: Volkswagen Group of America, Inc. (Audi) is recalling certain 2017-2020 A4 Allroad, A4 Sedan, 2018-2019 RS5 Coupe, 2019 RS5 Sportback, 2018-2020 A5 Cabriolet, A5 Coupe, A5 Sportback, S4 Sedan, S5 Cabriolet, S5 Coupe, and Audi S5 Sportback vehicles. The cable connecting the seat heater to the Passenger Occupant Detection System (PODS) may have a contact fault, causing the software to misdiagnose a malfunction and disable the passenger air bag.

Risk: A disabled passenger air bag increases the risk of injury in the event of a crash.

Fix: Dealers will replace the connecting cable and either the heating mat or entire seat cover, free of charge. Owner notification letters were mailed January 7, 2022. Owners may contact Audi customer service at 1-800-253-2834. Audi's number for this recall is 74E3. This recall is an expansion of Recall 19V-547 (74D9). Vehicles previously repaired under 19V-547 will need to return for the new remedy.

Engine · reported Mar 6, 2025
I don't know because dealer will not allow me to inspect engine or send me a response to what caused failure. Seems by the sounds coming from the top end of the motor most likely cause is that rocker arm (or possibly a valve train)component failed, noise coming from top end. Of course the failure was just after the 50k warranty by about 17 k miles. So roughly 66-67 k miles. The original estimate was a new long block at approx. 31k cost to me. Eventually after complaining significantly it was settled at 14k plus tax.
