The control module stored U2019 because it detected a problem with: Audio Voice Module Not Responding.
U2019 relates to Audio Voice Module Not Responding. Use a quality scan tool, follow wiring diagrams for your vehicle, and confirm tests before replacing expensive parts.
When U2019 is set, the vehicle’s diagnostics detected an issue described as: Audio Voice Module Not Responding. In practice, the ECM/PCM (and related modules) compare sensor inputs, commanded outputs, and self-tests for that subsystem. The exact repair depends on whether the fault is wiring-related, component-related, or a rationality/performance issue for this circuit or system.
Tip: Use a scan tool that shows live data and freeze frame for the conditions when the code set.
Moderate: Communication faults can disable features or store multiple warnings until the network or module issue is fixed.
Short trips may be okay if the vehicle feels normal, but have it diagnosed—especially if performance, safety warnings, or overheating are present.
Avoid heavy acceleration, towing, or long highway drives until the cause of U2019 is confirmed and repaired.
$100 – $1,800+ depending on cause
| Repair type | Typical range |
|---|---|
| Diagnostic And Minor | $120 – $600 |
| Common Component Work | $100 – $500 |
| Major Subsystem Repair | $400 – $1,800+ |
| Severe Or Replacement | $150 – $900 |
Schedule diagnosis if the check engine light is on, drivability is worse, or you notice new noises, smells, or warning lamps. For safety-related (SRS/ABS) or overheating symptoms, prioritize a qualified shop immediately.
U2019 is reported across many platforms including Volkswagen, BMW, Mercedes-Benz, Audi. Always use VIN-specific service information for testing limits and calibration steps.
U2019 indicates a fault involving Audio Voice Module Not Responding, based on what the control module detected during self-tests or live monitoring.
If the vehicle runs normally and no warning lights are flashing, short trips may be reasonable—but avoid ignoring symptoms like misfire, overheating, ABS/SRS warnings, or major loss of power.
Typical repairs often fall in the ranges shown on this page, but final cost depends on labor rate, parts quality, and whether the issue is wiring vs. a major component.
Most shops start with wiring/connectors and the directly monitored component for “Audio Voice Module Not Responding,” then expand testing if the fault returns.
It may become intermittent, but if the underlying fault remains, the code will usually return—especially after a drive cycle.
Low system voltage can cause odd sensor/module behavior, but you should still validate the actual DTC and perform normal circuit/component tests.
