alarm on 2015 x5 is high pitch and soft
Hello All,
Got my car back from service tonight and the alarm is now high pitch and soft/quiet. I did not notice until later when I got home and had to lock it. I've never seen this with BMW and cannot find anything like it on the web. Any ideas?
Is there a battery? I saw another post that says don't arm and let the main battery charge it an alarm battery???
Thanks
