Customer states:
• After opening the driver and/or front passenger door, the driver and/or front passenger seat sporadically
moves to an implausible position. The Entry Assistance feature can be activated or deactivated in the MMI.
• After entering and starting the vehicle, the driver and/or passenger seat does not return to its original position.
Instead, the seat reverses its direction and moves all the way back. After pressing the seat memory switch, the
seat moves to the selected memory position.
Technical Background
This concern only affects vehicles with power seats with memory feature.
While the seat moves during Entry Assistance, a brief action by the driver/passenger (e.g. applying the brakes,
pushing against the footrest) causes a voltage peak in the seat control module. As a result, the overload limit is
activated, causing the seat to reverse its direction of movement.

Technical Service Bulletin
In the old software, the overload limit was programmed with this low force value to ensure that the pinch
protection is sensitive enough when the seat moves backward. In contrast to the old software, the new software
can distinguish between forward and backward movement and define different forces respectively. Since the force
during forward movement is not subject to pinch protection requirements, it can be higher in the new software.
Production Solution
An improved software to address the condition was implemented in series production with model year 2021 in the
driver seat control module, J136 (address word 0036) and passenger seat control module, J521 (address word
0006).
Service
This TSB replaces Pending Service Solution (PSS) TSB 2059031: PSS 72 Front seats entry assistance
sporadically inoperative.
SVM Update Instructions
Tip: Prior to performing this SVM Update, please inform the customer that all seat memory settings will
be lost. It is not possible to remotely store their settings or to restore them after the SVM Update has
been performed.
A6, A6 allroad, A7, Q8, and RS Q8:
1. Do not follow this TSB. Please perform Campaign 72K6 instead since it also contains the seat control module
software update described in this TSB.
A8, Audi e-tron quattro, and Audi e-tron Sportback:
1. Follow all instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions.
2. Update the driver seat control module, J136 (address word 0036) and passenger seat control module, J521
(address word 0006) using the SVM action code as listed in the table below, if necessary:
