Diagnosis

These Audi vehicles are equipped with a capacitive steering wheel. This steering wheel features touch sensors designed to detect if the driver's hands are on the wheel. This system ensures driver attention when using driver assist features like Active Lane Assist and Traffic Jam Assist.

To diagnose the root cause of the "Audi Active Lane Assist malfunction U112300" or "Traffic Jam Assist malfunction U112300" messages, technicians should read the measured value data from the Data Bus On Board Diagnostic Interface (Gateway) - J533 (address word 0019). Specifically, they should check the status of IDE12609 - Steering wheel touch recognition, status. If a fault is indicated for this measured value, it confirms an issue with the capacitive steering wheel.

Repair Procedure Summary

The primary repair for this issue, once diagnosed, involves replacing the capacitive steering wheel. The replacement must be performed according to the detailed instructions provided in the Audi repair manual. This ensures the new steering wheel is correctly installed and calibrated, restoring the functionality of the driver assistance systems.
