Customer states:
 On the A5/S5/RS 5 Coupe and
Cabriolet that are equipped with S
Sport Seats (PR Code Q4Q) the
customer may report that the
seatbelt positioner is intermittently or
statically inoperative.
Note:
Only vehicles with S Sport Seats (PR
Code Q4Q) are affected. The seatbelts
function normally, only the seatbelt
positioner is an issue (Figure 1).
Workshop findings:

Figure 1. S Sport Seats, PR Code Q4Q in the S5 Cabriolet.

 No DTC’s are stored.

Technical Background
Depending on the seat version with which the vehicle comes equipped, the seat could be adjusted to a position
where the seatbelt positioner arm could make contact with the seatback e.g. seat adjusted fully upward and
seatback tilted forward. The A5/S5/RS 5 Coupe and Cabriolet equipped with S Sport Seats (PR Code Q4Q) are
currently programmed to not activate the seatbelt positioner when the seat is adjusted in this way. The A5/S5
Cabriolet equipped with S Sport Seats PR code Q4Q are not at risk for contact between the seat and the seatbelt
positioner due to seat to belt positioner tolerances.

Production Solution
A software change has been implemented in production that changes the behavior of the seatbelt positioner.

Service
On the A5/S5/RS 5 Coupe and Cabriolet an update to both seat control modules with the SVM code indicated in
the table below is required. No further work is necessary. The seatbelt positioner will operate in all seat positions.
SVM Update Instructions
1. Follow all instructions in TSB 2011732: 00 Software Version Management (SVM), operating instructions.
2. Update both seat control modules using the SVM action code as listed in the table below, if necessary:
