When all FRM (Footwell Module) functions on a BMW stop working, the issue is often caused by corrupted FRM data. In this guide, we’ll walk through how to repair a BMW XEQ384 FRM module using the Xhorse VVDI PROG.
Step 1: Remove the FRM Module
First, remove the FRM module from the vehicle. This allows us to read, edit, and write the data safely on the bench.
Step 2: Backup FRM Data

Step 3: Write Data Back to the FRM
1. Select FRM-E-SERIES-XEQ384-WRITE in VVDI PROG
