2014-2018 BMW i3 & i3s Instrument Cluster: Fixing Blank Screens and Programming a Used Unit

Symptoms of a Failing Instrument Cluster

Failures in the BMW i3 and i3s instrument cluster often manifest as problems with the display screen rather than a complete loss of function. Because the vehicle relies heavily on this screen, any issue can be distracting and concerning.

1. Screen Flickering, Intermittently Blank, or Rebooting

The most common complaint is a screen that flickers, goes completely black for a period, and then may or may not come back on. Sometimes this is accompanied by the iDrive system in the center of the dash also rebooting. This can be caused by a software glitch, a failing internal component in the cluster, or an issue with the main head unit that sends signals to the display. In many cases, the issue resolves itself after the vehicle goes to sleep but can reoccur randomly.

2. Display Shakes or Shifts to the Left

Some owners may experience the display content shaking, vibrating, or appearing shifted to one side. This is a known issue addressed by BMW. For vehicles produced up to January 31, 2018, this often indicates a poor internal connection that requires replacing the cluster. For later models, it may be a software issue that can be resolved with an update.

3. No Turn Signal Sound or Warning Chimes

If you notice your turn signals are working visually but you no longer hear the "tick-tock" sound, the internal speaker in the instrument cluster has likely failed. This speaker is also responsible for other audible warnings. Repairing this requires removing and disassembling the cluster to replace the small internal speaker.

4. Physical Damage to the Screen Cover

The clear plastic cover over the display can become cracked from impact or may even separate from its adhesive and fall off. BMW does not sell this plastic cover as a separate part. This means that even for minor cosmetic damage, a complete instrument cluster assembly is the only official new part solution from the dealer.

Known Issues, TSBs, and Recalls

While there are no direct recalls for the instrument cluster itself, several Technical Service Bulletins (TSBs) and relevant recalls affect the overall vehicle systems.

Technical Service Bulletins (TSBs)

• SI B62 08 18: Addresses the instrument cluster display shaking or shifting to the left. The fix depends on the vehicle's production date, with earlier models (to 01/31/2018) potentially needing a cluster replacement and later models requiring a software update.
• SI B62 11 17: Pertains to a gray haze appearing on the cluster face, often after being cleaned with a microfiber cloth.
• SI B62 12 15: Notes an issue where the outside temperature display in the cluster may be implausible.

Relevant Recalls

No recalls target the instrument cluster directly. However, owners of these vehicles should be aware of other significant safety recalls:

• NHTSA Campaign 18V755000: Affects some 2018 i3 and i3s models. A problem with the Electric Motor Electronics (EME) module could cause a sudden loss of power, shutting down the vehicle. The remedy is to replace the EME module.
• NHTSA Campaign 17V720000: Affects all 2014-2018 i3 models. The airbag control unit software needed an update to better protect smaller, unbelted drivers in a frontal crash.
• NHTSA Campaign 17V087000: For i3 models with the Range Extender (REx), the fuel tank vent line could rub against a cable, potentially causing a fuel vapor leak.

Buying a Used Instrument Cluster

Due to the high cost of a new cluster from BMW, a used OEM unit is a popular and cost-effective choice. However, there are critical factors to consider before buying.

What to Check Before You Buy

• Physical Condition: Carefully inspect the photos of the used part. Look for deep scratches or cracks in the clear plastic cover, as this piece is not sold separately. Check for any signs of damage to the housing or electrical connector.
• Part Number: While many part numbers may be compatible, it's best to match the number from your original cluster if possible. Part numbers can be superseded, so check with the seller for compatibility.
• Mileage on the Donor Vehicle: The mileage displayed on a used cluster is from the vehicle it came from. This is irrelevant because the cluster will need to be reprogrammed anyway. Do not pay more for a "low mileage" cluster.

Programming a Used Cluster

The vehicle's mileage and VIN are stored in multiple locations, including the cluster and a body control module (like the FEM or BDC). When a mismatch is detected, a tamper dot appears. To install a used cluster correctly, it must be "virginized" (reset to a factory state) and then coded to your car. This is not something a typical DIY mechanic can do without specialized tools.

You have two main options:

1. Mail-In Service: Companies specialize in BMW electronics programming. You will typically need to mail them your used cluster and your car's original body control module. They will program the cluster to match your car's data and send the parts back.
2. Remote Coding: Some services can remotely code the cluster to your car after you've installed it. This requires a specific cable (ENET cable) and a Windows laptop to connect the car to the internet for the technician.

Replacement Overview

Physically swapping the instrument cluster is a straightforward job.

• Difficulty: 2 out of 5 (physical install), 5 out of 5 (programming)
• Time: 0.5 hours for physical removal and installation.

The basic steps involve:

1. Lowering the steering wheel to its lowest and most outward position for access.
2. Removing two Torx screws located at the top of the cluster.
3. Carefully pulling the cluster forward and tilting it down to release it from the dash.
4. Disconnecting the single electrical connector at the back.
5. Installation is the reverse of removal.
