Sounds like the common fault with the Audi alarm whereby the backup battery for the alarm is shagged, so it'll keep going off especially when its cold as the voltage drops below the required threshold & it thinks someone is tampering with it.
Unfortunately the alarm is a sealed unit so you have to replace the whole unit. IIRC they're £80-£100.
