U0160: Kommunikationsverlust mit dem Steuergerät der akustischen Warnung

Was zu tun ist

Until this is fixed, assume the car cannot warn you with a sound, and reverse as though it has no parking sensors.

A warning light that fails is obvious. A warning noise that fails leaves nothing behind at all, so you go on relying on beeps that will never come — the seat belt reminder, the lights-on chime, the parking sensors, and any blind spot or collision alert, most of which are entirely audible.

One check first, because it costs nothing and may point somewhere else entirely. Does the radio still work? Do the dashboard gauges still work?

On most cars the chimes are not made by a separate buzzer — they are played through the stereo's amplifier or generated by the instrument cluster. So if the radio has gone silent too, the stereo is the fault; if the gauges have stopped, the instrument panel is. Either is a different repair from the one this code names, and telling the garage which saves real time.

If your car is electric or a hybrid, raise this as a priority. These cars must make a sound at low speed so pedestrians can hear them, and on some designs the same module produces it. A silent electric car in a car park is a genuine hazard to someone who is listening rather than looking.

Was dieser Code bedeutet

The audible alert module has stopped being heard from. The general reasoning is at U0100, and U0461 makes the case for taking a silent vehicle seriously — that the failure of the entire audible warning layer leaves no trace by definition.

Everything on that page applies here and does not need repeating. What silence adds is a diagnostic shortcut worth knowing.

On most vehicles the chimes are not made by a dedicated buzzer any more. They are synthesised and played through the audio system's amplifier, or generated by the instrument cluster. So the first question is not about this module at all: does the radio still work, and do the gauges?

  • Radio dead as well — the fault is the head unit or the amplifier, and U0184 or U0186 is the better page.
  • Gauges dead as well — the fault is the instrument cluster, and U0155 is the better page.
  • Both fine and the vehicle merely silent — then this module genuinely is its own unit, which is the less common case.

That check costs nothing and redirects a good share of these codes to a different page entirely.

And the standing instruction from U0461 holds until it is fixed: reverse and manoeuvre as though the vehicle has no sensors, check seat belts and lights by hand, and treat the driver assistance systems as absent rather than working quietly. On an electric or hybrid vehicle raise it as a priority — the low-speed sound required for pedestrians is generated by the same module on some designs, and a silent electric car at walking pace is a hazard to anyone listening rather than looking.

Die Seiten entstehen aus öffentlichen Quellen und aus dem, was andere festgestellt haben, nie aus den Serviceunterlagen des Herstellers; für Ihr konkretes Fahrzeug können sie daher falsch oder unvollständig sein. Ein Teil des Beschriebenen birgt echte Gefahren: Hochspannung, Kraftstoff unter Druck, gespeicherte Energie sowie heiße oder bewegte Teile.

Was einen Bericht lesenswert macht:

  • Das Fahrzeug — Marke, Modell, Baujahr und Motor. Derselbe Fehler verhält sich auf jedem anders.
  • Was Sie gemessen haben, nicht nur, was Sie getauscht haben.
  • Was es tatsächlich behoben hat — oder dass nichts es behoben hat, was ebenso nützlich ist.
