Audi A3: Syncing Key Fob (8V 2016)

A3 Sportback 8V 2016 TDI 2.0

Dear forum members,

Does anyone know if it's possible to resynchronize the original remote keys using VCDS (current update RKS26090)?
Due to undervoltage during startup, the control unit ("central electronics") generated error messages and, among other things, activated the transport mode, which I have already deactivated.
I suspect that the keys are no longer synchronized, or that the control unit has lost the data.

What have I already tried!
1. Die Starterbatterie abgeklemmt (kpl. Reset).
2. Transport mode disabled.
3. All error entries (e.g., implausible findings) have been deleted.
4. All proposed methodologies (forums and AI) were tested without a diagnostic device.

I can't find any adjustment channels for this in control unit 09 (central electronics).

- The immobilizer is still working.

Has anyone else experienced this issue, or does it need to be reactivated by "customer support" through the manufacturer's server?

Sure, here's the translation:

"Thank you in advance."

Best regards, KLU062.

Hi,
Do you have any non-removable error entries or functional limitations? Without a clear indication, I would disregard the "assumption."
Autoscan?

Hello Herbert,

Thank you for the quick response.
I had a scan performed, and it only showed error entries in the central electronic control unit and the engine control unit due to the low voltage. I cleared those errors, and they haven't reappeared.

Werde trotzdem am Wochenende nochmals einen kpl. SCAN.

Best regards,

Klaus.
