As title really, been told it does'nt, but seems odd as it would help in diagnosing an alarm issue. What sort of checks can a dealer do on the alarm system? Can they adjust the sensitivity or anything else??

Thanks.

I had a look at an old Passat the other week, that recorded the last 4 or 5 alarm sources, so I would think that a new Octavia would.

Yes, alarm triggers are recorded, as per my other posts on the subject
