Power transmission -> Selector mechanism for Your Audi RS E Tron Gt 4 Door First Generation (2021-2026)

Selector mechanism  
684_172  
The driver’s desired transmission position (R, N or D) is transmitted via the selector mechanism to motor control unit J623.  
The data are transmitted to data bus diagnostic interface J533 via the infotainment CAN bus and from there to motor control unit  
J623 via FlexRay.  
Transmission position D is the only position available for driving forwards. The gear selection can be influenced using the Audi drive  
select modes efficiency, comfort and dynamic.  
The parking lock function is activated in conjunction with the electromechanical parking brake. This happens when button E538 is  
pressed to activate the parking brake when the vehicle is stationary, and this status is communicated to the motor control unit. It is  
also possible for the parking lock function to be activated via the Auto-P function as part of the exit concept.

From the basic position – X – there are two forward positions (A1, A2) and two rearward positions (B1, B2). The selector lever re-  
turns to the basic position – X – after every operation.

Shift behaviour  
When the vehicle is driven in transmission position D, 2nd gear is normally used for driving off. If transmission position R is selec-  
ted and then position D, 1st gear remains selected. At driving speeds above approx. 20 km/h, the vehicle shifts into 2nd gear.  
Manoeuvring, rocking the vehicle backwards and forwards to free it  
The software lock is activated in transmission position N after approx. one second. This allows rapid changing of the transmission  
position from D to R and vice versa without applying the brake. This makes it easier to change transmission positions when ma-  
noeuvring. It also makes it possible to free the vehicle if necessary by rocking it forwards and backwards.  
Note  
A tone will sound briefly when R is selected.  
Activating the parking lock function (P-ON)  
The button for electromechanical parking brake E538 is marked with a white illuminated symbol.  
If button E538 is pressed at vehicle speeds < approx. 2 km/h, the parking brake is actuated via ABS control unit J104. The parking  
brake brings the vehicle to a standstill by blocking the wheels on the rear axle.  
The red symbol for the parking brake appears in the instrument cluster.  
Directly after the rear wheels are blocked by the parking brake, the parking lock function is activated by blocking two-speed trans-  
mission unit 0ME on the rear axle. There is no physical parking lock. By engaging two gears simultaneously, the transmission unit  
blocks itself, which acts as a parking lock. Parking lock indicator lamp K320 lights up on the selector lever control.  
Auto-P function (P-ON/OFF)  
The parking lock function is activated automatically if the drive system is switched off when transmission position D or R is selected  
and the vehicle is stationary.  
If the vehicle’s drive system is activated, the parking lock function is deactivated when the driver presses the brake pedal and se-  
lects transmission position D, R or N.  
Exit concept (P-ON)  
The parking lock function is automatically activated if the driver’s door is opened and the driver’s seat belt is unbuckled when the  
vehicle is stationary with transmission position D or R selected.  
Transmission position N  
The parking lock function remains deactivated (P-OFF): Car wash function  
The parking lock function remains deactivated if the ignition is switched off when transmission position N is selected. A 30-minute  
countdown starts, during which time the parking lock function remains deactivated. After approx. 30 minutes, the parking lock  
function is activated automatically. The countdown is interrupted if the ignition is switched on or the vehicle begins to move.
