Long coding cannot be saved

[porter]

I tried to use the OBDEleven app (pro version) to make some changes to my car (Audi A4 B9 2019).
Everything seems to work fine (connecting, access to the modules, ...) but when I use the long coding method, changes cannot be saved.
After changing a bit, I long press the green button, but I don't get the message 'changes accepted'. When going back, it ask me to save changes first (which confirms me that the change is not applied).

Any ideas to solve this?

What exactly happens if you long press the green button?
Normally there should be a little circle in the upper center which indicates the progress.

Btw i thought newer cars are having the long coding part in adaptations.
Have you checked your adaptations?

When I long press the green button, there is indeed a little circle turning around to indicate the progress. But after that, nothing happens.
The problem is not entering the long coding, it is saving the changes.

I just got a mail back from OBDEleven support saying that I should leave the hood open as the newer cars would some kind of security on it. Will try that in the next days.

Edit: Everything works fine with the hood open!

From 2019 production year Audi has installed OBD firewall function which is blocking any mofifications to the vehicle until hood is closed, so to be able to use one click apps, Long coding or adaptation functions you will need to open the hood.

So I clicked on the long code to disable my TPMS and change to a 24 hour clock. My OBDeleven says the changes were accepted. But when I start my car I still see the TPMS warning light illuminate on the dash momentarily before going out. In addition, I still can't access the TPMS display for the tires in the centre console with the ignition on. So did it work or didn't it?
