2021 Audi Q7 Power Rear Lid Not Opening via Remote Key TSB

Symptoms

Owners of 2021 Audi Q7 and SQ7 models may experience issues with the power rear lid. The primary symptom is that "The rear lid only unlocks and/or opens sporadically when using the remote control key." This means the tailgate may not respond consistently when attempting to open or unlock it with the remote.

Technical Background

Audi has identified the root cause of the sporadic power rear lid operation. The issue stems from an incorrect identifier within the Target Data Container (ZDC) and an improperly set debounce time for the remote control key in the data set used by the rear lid control module, J605 (address word 006D). This incorrect setting affects vehicles equipped with the convenience key feature.

Production Solution

Audi implemented a production solution to address this condition. A new Target Data Container (ZDC) update for the rear lid control module, J605, was introduced in calendar week 23 of 2021 (CW23/2021) to correct the identifier and debounce time settings.
