OK...I'll take a shot at this one. Likely a "distant shot", but maybe worth thinking about.

Alarm.

You say behind the glove box. On a 126 and I'll bet on the 124 as well, the stock alarm system is beneath the passenger side foot well. That's "beneath" the glove box...sorta. Noises and their point of origin can be confusing.

Could this be the alarm controller yacking at you?

This suggestion may not be valid if the alarm system is the original factory unit. I want to say that the factory system would not stop the car from starting, but simply sounded an alarm in the event of dampering. Someone correct me if I'm wrong.

If your alarm is after-market, there's a much stronger possibility it could be involved here.
