U0184 on Porsche
Lost Communication With Radio
U0184 on Porsche vehicles indicates lost communication with radio. Au7o has documented this code across 2 Porsche models — most commonly on 911, Taycan. This network code means a module stopped receiving expected communication messages from the radio/audio module over the vehicle's data bus. When the radio module goes offline or its bus connection fails, this code is logged. On some vehicles the audio module also acts as a network gateway, so its loss can trigger several related communication codes. Symptoms are typically a dead or unresponsive radio/infotainment system; it does not affect drivability.
Common Causes of U0184
- •Loss of power or ground to the radio/audio module
- •Blown radio fuse
- •Wiring or connector fault on the communication bus
- •Faulty radio/audio control module
- •Corroded or loose module connector
- •Network/bus wiring short affecting multiple modules
U0184 on Porsche by Model
Porsche 911(1 issue)
- PCM Central Computer Software 37xx - Black Screen, Audio and Navigation Failures2022-2023
Porsche Technical Information 65/23 ENU 9152 covers 911 (992) model years 2022 through 2023 running central computer (PCM) software version 37xx. Porsche describes the condition as "the PCM cannot be switched on, fails intermittently during vehicle operation or starts up again independently," and lists the error patterns explicitly: the PCM screen remains black; there is no sound output and the hands-free device is faulty; the navigation display fails; and the PCM can only be started again after some time or starts up again on its own. On cars with the BOSE Surround Sound System (M-no. 9VL) or Burmester 3D High-End Surround Sound System (M-no. 9VJ), the sound settings under Media are additionally lost after bus rest - "Heights and depths" and "Balance and fader" become unticked and the bars reset to zero - and Real Time Traffic stops showing traffic jams in the route monitor text. A separate MY2022 workshop campaign, WNT1 (TI 236/22 ENU), re-programs the Connect control unit and central computer with optimized software. Owners report the same blank-screen and reboot behaviour on Rennlist, where the usual workaround is a hard PCM reboot rather than a permanent fix.
Porsche Taycan(1 issue)
- Infotainment and Vehicle Software Bugs2020-2025
The Taycan PCM infotainment system and vehicle management software experience frequent bugs including screen freezes, Apple CarPlay disconnections, climate control malfunctions, and navigation errors. OTA updates have improved stability but new bugs are occasionally introduced with each update cycle.
