Initial publication
Customer states:
The wireless ASI (Apple CarPlay or AndroidAuto) connection is lost or interrupted reproducibly at certain specific
locations (for example, near toll booths or other microwave transmitters).
The connection is usually reestablished when leaving the affected area.
The connection drop-outs manifest from an interruption in music streaming up to a temporary complete loss of the
wireless connection to the vehicle.
Workshop findings:
• No relevant DTCs are stored.
Technical Background
Outside interference on the 2.4GHz and 5GHz wireless frequency spectra can cause the ASI connection in the
vehicle to become unstable.
Production Solution
Not applicable.

Technical Service Bulletin
A robustness measure has been introduced to improve system behavior when driving in an area with strong
outside interference on the WiFi spectrum:
For A3/Q3 vehicles:
1. Turn on the ignition and wait approximately five minutes for the MMI system to be fully initialized.
2. Complete the test plan “Replace control module J794”, including all populated sub test plans via GFF in ODIS,
without actually replacing any parts.
3. When asked if the old control unit is still installed in the vehicle, select “no”.
4. Perform a vehicle bus sleep cycle.
For Q4 vehicles:
An optimization is expected to be released by the end of Q1/2023 (subject to change)
This measure will reduce the susceptibility of the vehicle to external interference on the WiFi frequency spectrum.
However, due to its nature, it cannot be ruled out that strong interference may still cause the ASI connection to
drop. Due to physical limitations, this may not always be preventable.
A wired ASI connection can be used. Wired connections are not susceptible to the same kind of interference.
