i have acquired a very low mileage 1997 S500coupe outfitted with the parktronic system.

and i am experiencing strange behavior from it. especially from the front bumper sensors. never from the rear sensors.

most of the time, when coming to a stop at a light, the dash sensors illuminate, but seeing nothing nearby, do nothing.

but occassionally, with nothing nearby, the front sensors will fully illuminate as if there is a hazard close to being impacted and the audible will sound.

i can go from an intersection with nothing close where this will occur. then to another one where i have a car next to me and yet no similar warnings will occur.

why is this do you think?

all ears.
