Xhorse VVDI Key Tool Plus Feedback: Duplicated Audi A5 2013 successfully.
There push in dash on A5 does not need to be proximity key. I think in this case if it was slot and also prox.
Simple guide:
Read BCM, preload key, and learn key.
If the key is already scheduled, pre-loading the key in the last step it stays at 10 %. Then you need to clean the key.
Look at the following image.
