U0155 on Land Rover by model: symptoms, diagnosis and fix
Owners of 2023-2025 Range Rover Sport models frequently report the curved Pivi Pro center display freezing, rebooting, going black, or losing audio/navigation/climate control responsiveness. Because many vehicle functions are integrated into the touchscreen, these failures can also disable surround-view cameras, parking graphics, Bluetooth, and HVAC controls until the system reboots. The issue is widely discussed on owner forums and reflected in complaints involving software instability on the new-generation infotainment platform.
Common Symptoms
- Center screen freezes
- Display goes black
- Backup camera unavailable
- Surround camera image missing
- Bluetooth disconnects
- Navigation or audio stops working

How to Fix
The first step is checking for infotainment software updates and applying the latest over-the-air or dealer-installed package. If the problem persists, dealers typically inspect the infotainment control module, display connections, camera module communication, and network faults on the vehicle's Ethernet/CAN architecture. In some cases, module replacement or reprogramming is required if repeated hard resets do not resolve the issue.

Frequently asked questions
What does U0155 mean on a Land Rover?
U0155 stands for "Lost Communication with Instrument Cluster." This is a network communication code meaning a control module (usually the engine or body computer) has lost communication with the instrument cluster over the vehicle's data bus. Modern vehicles share information between modules over a network (such as CAN), and the cluster both displays data and relays messages. When messages from the cluster stop arriving, this code sets. You may see warning lights, dead or erratic gauges, missing displays, or other modules acting up. It usually points to wiring, power/ground, or the cluster itself rather than the engine. On Land Rover it is documented across 1 model: Range Rover Sport.
What are the most common causes of U0155?
The most common causes of U0155 are: Faulty instrument cluster, Loss of power or ground to the cluster, Damaged or corroded CAN bus wiring, Loose or corroded connectors at the cluster, Blown fuse feeding the cluster, Short or open on the communication bus, A different failed module dragging down the bus.
