Vehicle: 2017 Audi A4 Premium Plus

Hey everyone,

I've been having some frustrating issues with the MMI system in my 2017 Audi A4 Premium Plus. Lately, the screen has started flickering intermittently, especially when I first start the car. Sometimes it even freezes completely, making it impossible to change radio stations or access navigation.

It's really annoying, and a bit concerning for a car that's only a few years old. I've tried restarting the car, but the problem often comes back. Has anyone else experienced this with their A4, or other Audi models from this generation?

Is there a known fix or a software update I should be looking for? Any advice on what might be causing this would be greatly appreciated before I take it to the dealer.

ClearTheCode admin answer:

MMI system issues like flickering or freezing are not uncommon in certain Audi models, including the B9 generation A4. This can be a frustrating problem, often pointing to either a software glitch or a hardware component issue within the infotainment system.

Here's what you should consider:

  1. Perform a Hard Reset: Many Audi MMI systems can be reset by holding down a combination of buttons (often the main MMI knob, the top right function button, and the navigation/map button simultaneously for about 10-15 seconds). This can clear temporary software glitches.
  2. Check for Software Updates: Audi frequently releases software updates for their MMI systems. A dealership can check if your vehicle's MMI unit has the latest firmware. Outdated software can lead to various performance issues, including instability.
  3. Inspect Connections: While less common for intermittent issues, a loose connection to the MMI display or control unit could cause flickering. This typically requires professional inspection.
  4. Potential Hardware Failure: If software updates and resets don't resolve the issue, it may indicate a failing MMI control unit or the display screen itself. Components can degrade over time, leading to these symptoms.

When to See a Shop:

  • If the issue persists after attempting a hard reset.
  • If the problem significantly impacts your ability to use essential vehicle functions (navigation, climate control, safety warnings).
  • If you suspect it's a hardware issue or if the flickering becomes constant. A specialized Audi technician can perform diagnostics using ODIS (Offboard Diagnostic Information System) to pinpoint the exact cause, which might involve replacing the MMI control unit or the display screen. While there isn't a specific OBD-II code for MMI screen issues, the car's internal diagnostic system will log faults related to infotainment components.
