Bmw 320i 1992 theres light on the dashboard i dont know what is that, its like circle with three dots on the right and on the left red light next to the handbrake light

run fault codes and check for faulty TCM unit

mine is just a red circle with something like 3 lots of 2 dots on each side, is that like yours?

is there anyway you could draw it on the sight or video picture so i can see it i dont know the model by heart but it sounds like low prestone in the tank sensor

I believe this means that your brake pads will need to be replaced soon

sounds like your brake lining light. It means your brakes have worn below specification. The light to me kinda looks like a yellow circle with two dashes on one side and two on the other and they follow the curvature of the circle. On an x3 you can get a pretty good view of the brake pads looking through the wheel.

This should be your brake pad wear light, Either brake pad is worn or loose wire on connection or wear sensor is faulty/damaged

Need to replace your brake pads.

If it's the red circle with three lines on each side, it's something related to the brakes. If I remember correctly, the lining.

It means that your brakes are worn. REMEBER: If you are going to replace them yourself remeber to also buy the brake sensor witch will be located on the on the right or the left hand side Im not sure . . . .It is just a wire connected to a sensor that clip's on the outer brake pad.

usually beeping noise is associated with warning signs (to make the driver notice)....so perhaps the electrical connection got shorted somehow cuz of dirt or water.....i think you should have the electrical wiring checked at the service shop...
