2013-2017 Audi S5 Instrument Cluster: Fading Screens, Faulty Gauges, and Component Protection

Symptoms of a Failing Instrument Cluster

Failures in the 2013-2017 Audi S5 (B8.5 generation) instrument cluster typically revolve around the central digital display and backlighting. While complete failure is rare, these specific symptoms are common.

1. Fading or Blank Center Display

The most reported issue is the failure of the central color Multi-Function Display (MFD). The screen may begin to fade, especially on hot days or after the car has been running for a while. Eventually, it can go completely blank or black, making it impossible to read trip data, navigation, or warning messages. In some cases, the display works intermittently, recovering after the car cools down. This is often caused by a failing LCD panel or a loose internal ribbon cable.

2. Pixelated Screen or Lines on Display

The display might show vertical or horizontal lines of dead pixels, which can be red, green, or blue. This can start as a single line and worsen over time, obstructing the view of the information behind it. This indicates a hardware fault within the LCD screen itself. While many TSBs for this issue relate to newer models, the problem stems from similar screen hardware technology.

3. Flickering or Dead Backlighting

The LED backlighting for the analog gauges can start to flicker or fail entirely. This can affect one section of a gauge (like part of the speedometer) or the entire cluster, making it difficult or impossible to see your speed and RPMs at night. This is usually due to failing LEDs or bad solder joints on the cluster's circuit board.

4. Inaccurate or Stuck Gauges

Less commonly, the physical needles for the speedometer, tachometer, fuel, or temperature gauges may behave erratically. They might get stuck, provide incorrect readings, or not move at all. This is often due to the failure of the small stepper motors that control each needle.

5. Warning Lights and Communication Errors

A failing cluster can cause false warning lights to appear or prevent legitimate warnings from showing up. In severe cases, it can lead to communication errors with other modules in the car, potentially triggering a "No Signal/Communication" fault code like U0155. In rare instances, a complete cluster failure can even prevent the car from starting because it is a key part of the vehicle's immobilizer system.

Buying a Used Instrument Cluster

Purchasing a used OEM cluster can be a cost-effective solution, but it requires careful consideration due to the Component Protection system.

What to Check Before Buying:

• Verify the Part Number: Match the OEM part number exactly. Part numbers can vary based on model year, transmission type (manual vs. automatic), and features like adaptive cruise control. An incorrect part number may not be compatible. Common part numbers include 8T0-920-984-F and 8T0-920-983.
• Inspect the Screen: Ask the seller for clear photos of the cluster powered on, if possible. Look for any signs of fading, dead pixels, or lines on the central display. Be wary of any screen imperfections, as they are the most common failure point.
• Mileage Incompatibility: A used cluster will display the mileage from the donor vehicle, not your car's actual mileage. Adjusting the odometer is a specialized service and is legally regulated. The primary goal of replacement is to restore function; mileage correction is a separate, complex step. Some repair services can adjust mileage during programming.
• Plan for Programming: A used cluster is not a plug-and-play part. You MUST budget for professional programming to remove Component Protection. Contact a local Audi dealer or a European auto specialist *before* you buy the part to confirm they are willing and able to adapt a used cluster. Some dealers may refuse to program customer-supplied used parts.

Why Used OEM is a Good Choice

Despite the programming hurdles, a used OEM cluster is often a better choice than a cheap aftermarket alternative. OEM units are built to Audi's quality standards for fit, finish, and electronic compatibility. Aftermarket options are virtually non-existent for direct replacements, with most being expensive digital cockpit *upgrades*. Repairing your original cluster is another excellent option that avoids Component Protection issues entirely.

Known Issues, TSBs, and Recalls

As of mid-2026, there are no specific recalls or widespread Technical Service Bulletins (TSBs) from the NHTSA for instrument cluster failures on the 2013-2017 Audi S5 in the US market. However, Audi has issued numerous TSBs for similar issues (blank screens, pixel errors) on newer models, such as TSB 90 24 14 and 90 22 41, which indicates a pattern of hardware issues in their virtual cockpit and digital display components. The problems seen in the B8.5 S5 are generally considered age-related wear rather than a specific manufacturing defect covered by a recall campaign.

Replacement Cost & Procedure

The physical replacement of the cluster is moderately difficult, but the electronic programming makes it a job for professionals.
