FAQ

Frequently asked questions

Why is my RNS-E asking for a code?
The unit lost power and its anti-theft lock activated. It happens after battery changes and repairs, and the fix is the same as any Audi unit, enter the correct 4-digit code once.
Can the RNS-E show its serial on screen?
Yes, and it saves pulling the unit out. The RNS-E can display its serial through the screen, the guide above walks through the route. If you cannot get the screen method to work, the AUZ serial is on the label on the casing.
What does the RNS-E serial look like?
The standard Audi format, 14 characters starting AUZ. Enter it exactly as shown, including the AUZ prefix.
How do I enter the code on the RNS-E?
The unit prompts for the code on screen when it starts. Enter the 4 digits using the controls and confirm. With the correct code it unlocks immediately and remembers it until the next power loss.
I fitted a second-hand RNS-E to my car. Can you decode it?
Yes. The code belongs to the unit, not the car, so a second-hand RNS-E just needs its own serial decoding. This is one of the most common orders we see for these units. For other Audi units, our main Audi radio code page covers the full range.
