You install it into a customer's car with a cracked screen.
The 7D interrupts that transaction.
Without the 7D: The cluster turns on, shows the Audi rings for 3 seconds, then locks. Dealer cost to unlock? $600 + towing + a two-week wait for "German approval." lfs s3 unlocker 7d
You have the hardware. You have the software. But the server says No .
