Sensor Lights I have a 2003 325xi and I have Sensor light on my Dash that looks like a circle but on each side of the circle it has 3 dashes on the outer ring. I just recently replaced the brakes and that light was on before hand and thinking it would go out. What is this sensor telling me.It is on my dash board on the right hand side next to my sensor that says Brake.Can you Help me please

Dash lights are on the same fuse as the tail lights. Dash lights not working is an indication that the tail lights are not working. The first thing to check is that the tail light fuse is not blown. Most of the time replacing the tail light fuse will restore both the tail lights and the dash/interior lights. If this is not the case you may have to trace the wires and look for a broken or unplugged wire in the harness.

1- look for sensor- usually in speaker grill on dash - passenger side- clean with windex and towel
2 - if no go- replace headlight switch- controls the daylight and always on lights-
3 if this does not help- need to replace daylight control unit- looks like amp - but silver with fins- usually behind glove box under dash

It's an yellow warning indicator lamp. It lights when front brake pads are weared. Now it's time to replace used brake pads!

If it looks like the symbol in the image below, it is your brake pad wear sensor.

Your front or rear brake pads are probably worn out (and are below the minimum thickness) and need to be replaced.

Or the wear sensor could be faulty and need replacement also.

you're car have a photo cell sensor that reeds light or darkness,if these sensor fail you're auto light will-not work.the easy way to check is look in top of you're dash you'll see a little round blue circle, that is the photo cell sensor unplug it and turn you're ignition on, now you have lights,buy a new photo cell sensor

Sounds like a lamp out indicator. look for a burned out bulb.

its the breaks if it is a circle with 3 dashes on each side it is the break sensor it indicares you are running out of breakes

does the one look something like this? IIIOIII or (((O)))

this is the brake wear indicator saying that you need brake pads somewhere on the car (front or rear).

the other sounds like you either have the traction control (its a button with either DSC or ASC written on it) turned off or its showing you that it is off because you need need brake pads.

Warning light for low or worn brake pads. Could also be a damaged sensor wire or connection. Most likely pads though.
