But if the "Door Open" sign appears in meter when you open the door. and only beep sound has disappeared.
then there might be some other issue.
have you checked the beep sound while reversing the car, or beep warning sound of car seat belt ?
(as according to my experience, there is only one beep speaker for all the warning sounds.
btw, keep in mind that car only beeps in the following conditions:
- if door is opened but Ignition key is off (NO BEEP)
- if door is opened and ignition is at On point or Key inserted (it Beeps with little delay, like beep beep beep.....)
- if door is open, and Parking or headlight in On (then it Beeeeeepssss.... contionously regardless of the ignition switch)
Also its better to check all the fuses in the dashboard if there is any burnt fuse .
