57 Door handle touch sensors (Audi advanced key) inoperative Release date: Jul 31, 2025

Condition

REVISION HISTORY

revision [owe [eupore

7 Revised header (Updated Customer Codes)

Revised Service (Updated verbiage, added image)

Revised Warranty (Updated verbiage)
6 | 07/31/2024 | Revised header (Updated with 2025 model years)
5 05/23/2024 | Revised header (Updated with all models to model year 2024)

Revised Technical Background (Updated concepts with new models)
+ The exterior door handle touch sensors (Audi advanced key) are inoperative on one or several doors.
+ The key blade can be used mechanically (driver door or trunk) or remote electrically (key remote buttons) to

unlock and lock the vehicle.
Technical Background
Concept-related restrictions
1. If the key is in the direct vicinity (e.g. same coat pocket) as a smartphone, the advanced key function may be

affected by interference due to phone signals.
2. If other transmitters operate in the same frequency range *e.g. mobile phones, TV broadcasters, wireless

headphones, remote controls of cranes, baby monitors, carports with photovoltaic systems and active

inverters, other vehicle remote controls, etc.), the advanced key function may have been temporarily switched

off, as it is not possible to clearly identify the signal.
3. If the customer reaches into the door handle while 2

touching the lock sensor to lock the vehicle (Figure 3b

1), the unlocking range of the sensor is activated @

at the same time. As unlocking has a higher “

priority than locking, the vehicle cannot be locked |

in this way. This may not be depicted very clearly

in the Owner’s Manual.
J

Figure 1. Reaching into door handle while touching the

lock sensor.
4. The Audi advanced key system needs a short response time for the key identification. When the door handle

is grabbed and pulled very quickly, the key may not yet be identified, and the vehicle does not unlock.
5. Unlocking the door after it is locked is not possible for a brief period. This allows the customer to check that

the door is locked by pulling the handle.

6. If an external device is plugged in to the 12 V socket or USB connection, its signals may interfere with the

advanced key function.

7. A3(8V), A4 (8K), AS (8T, 8F), AG/A7 (4G), A8 (4H), Q3 (8U), Q5 (8R), R8 (4S):

To reduce power consumption, the door handle touch sensors are deactivated after the vehicle has been

parked for a few days. It is then necessary to first wake the vehicle by pulling the door handle once and then a

second time to open the vehicle. In this situation, locking the vehicle with the Audi advanced key is only

possible after an ignition cycle.

Q7 (4M), A4 (8W) and AS (F5) up to production 45/2016:

The ignition must be switched on for the advanced key to work again.

All others:

The door handle sensors are no longer switched off after a stationary period.

8. If the vehicle battery is discharged, the energy management system gradually deactivates unnecessary

convenience functions. It is possible that the vehicle temporarily will not unlock with the Audi advanced key.

9. Please clean the door handle as follows: pull the a

handle and clean the areas between the handle —

and the body (Figure 2). al
