When Alex kindly plugged his Foxwell into my E89 this came up. Does anyone know what it means? The roof works ok by the way, at the moment.
Roof code question.

Might just be that you were opening / closing the roof when driving too quickly. Gemini (AI) says:
BMW A69E fault code indicates an issue with the vehicle's speed and soft top intermediate position, often seen in E89 Z4 models when the convertible top system operates while the vehicle is moving at too high a speed. This is typically a secondary, misleading code resulting from an actual underlying issue, such as A691 Hall Sensor VSW5.2 or other sensor, valve, or wiring faults within the convertible top system. To resolve it, you must identify and fix the primary fault, then clear the codes.
Understanding the Code
"Vehicle Velocity Too High":
The code's name suggests the system detected the car was moving too fast for the convertible top to be operated safely.
Secondary Code:
It often appears as a consequence of another issue, such as a malfunctioning Hall sensor or other components in the convertible top's control system.
Potential Causes
Faulty Hall Sensor:
A common underlying cause in E89 Z4s is a failing Hall sensor.
Valve Issues:
In some BMW models, related codes (like A69A-D) can indicate problems with valves in the hydraulic system, which could trigger the A69E code.
Wiring and Connector Issues:
Broken wires, particularly in the bends of the top's mechanism, can disrupt the signal and lead to the fault.
Misaligned Top:
If the top is not fully closed or has an issue in the trunk, the system can get confused, and the "Vehicle Velocity Too High" code may appear.
Troubleshooting Steps
1. Identify the Primary Fault:
Use a BMW-specific diagnostic tool (like ISTA) to read other fault codes. The primary code, often a sensor fault like A691, will point to the real problem.
2. Check the Hall Sensors:
Locate and inspect the Hall sensors, ensuring their connectors are fully seated and secure.
3. Inspect Wiring and Connectors:
Examine the wiring harnesses, especially in the sharp bends around the headrests, for any signs of damage or breaks.
4. Check Hydraulic System:
If the code relates to the hydraulic unit, inspect the hydraulic fluid level and check for damage.
5. Reset and Test:
After addressing the primary issue, use the diagnostic tool to clear the fault codes and test the convertible top system.
Consult a professional if you are unable to identify the underlying issue.
I wouldn't worry about it - see if it reappears. Can scan next time . . .
