Audi Q5 - One of the vehicles commonly affected by BCM2 EEPROM corruption issues
Picture this: you're rushing to an important meeting, you get into your beloved Audi, press the start button, and... nothing. Instead of the familiar engine roar - silence and an ominous message on the dashboard. This is exactly how our story begins today.
An Audi owner named Sarah faced exactly this problem. Her dashboard displayed the message "Ignition Lock Defective - Visit Workshop." This message typically misleads not only owners but also many mechanics, leading to unnecessary and expensive steering column replacements that cost thousands of dollars.

In reality, in most cases the problem lies not in the steering column, but in the Body Control Module (BCM2). Inside this module is an EEPROM (Electrically Erasable Programmable Read-Only Memory) chip that stores key data for starting the vehicle, including immobilizer information. Over time, the data in this chip can become corrupted, leading to the inability to start the engine.
