Hello all, I have an Audi A5 3.0 Tdi Quattro 112k miles 2013.

I’ve recently done a battery change as the original was over 12 years old. I coded the battery with my diagnostic tool by changing the serial number as my manufacturer wasn’t listed.

Now my alarm keeps going off randomly at night and I’m not sure why. I’ve had 13 triggers and all sources lead to value 12 - which I believe to be interior sensors.

Because of this I’ve currently disabled the alarm system completely and it’s stopped. However I would like to know if someone has experienced a similar issue and how to resolve this?

Any advice would be appreciated. Thank you.
