U101400 fault code

[J4K]

Hi everyone. My 2017 Audi A3 S-Line,2.0 TDI lost its Central Electrics (09) Long Coding after a flat battery. It's a 30-byte module. Could anyone with a matching car please pull and share their factory long-coding string so I can recover mine?

Some backstory if its helpful - i had the changed the negative terminal as I was having trouble with the start stop function and an overnight flat battery - turns out I had just forgot to replace a fuse i pulled. After doing a scan it flagged up the U101400- control module not coded properly, everything worked as it should but i changed it back to the original negative terminal in hopes it would clear the code - it hasn't and it seems theres nothing I can do to clear it.

Any help or advise would be greatly appreciated


Cheers

Facelift models don't have any coding for the BCM, so it's all zeroes. It only has adaptations. Removing power will not reset them.

Incorrectly coded means you likely removed or added a system which should be “coded” (set 09 adaptations).

If the car is fully stock and not modified in any way (or done retrofits or updates), go to the dealer and they can run SVM on the BCM so that the adaptations match with what's on the servers.
Or manually try to figure out what system is responsible for the error.
