Audi Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to Just Answer,
The error codes are specific to the manufacturer and used for their diagnosis when refurbishing the units. If any error code is displayed you will need to buy a new radio. You can purchase a factory re manufactured radio from this website for under $40.00.

The install is very straight forward, the only special tools you will need are "radio keys" which are also available on ecs tuning's website. They clip in in small slots in all 4 corners and are what release the locks that hold the radio in, after that it is just unplug the old one and plug in the new one. As far as the radio code, the new one will come with a paper with the code on it. Just follow the instructions in your original radio manual to unlock the radio. If you do not have the book, the procedure is simple. You hold the rds and pscan buttons in at the same time for approx 5 seconds, the display will turn to 1000, you use the radio preset buttons to change the 1000 to read the unlock code and then you press and hold the rds and pscan buttons in again for approx 5 seconds again and the radio will unlock. The first time a radio unlocks it will go through a learn cycle, the display should read learn. Be sure not to turn the ignition or radio off while it is in its initial learn cycle as it can damage the new radio.
