Meaning of brake and DTC light on?
 
Today, on the X3 two warning lights came on.

1. "BRAKE" light in yellow. It's in the center and has the word "BRAKE". When the parking brake is on, this light is red and is normal. It is not the ABS or the brake pad light.

2. DTC light is yellow. It's in the upper part of the tachometer. It is a yellow "4x4" with a triangle above it and a semi-circle halo over that.

It remained on after restarting the car but did not go on after restarting the car again. The brake pads are thick and not worn. The brake fluid level is normal.

Is this just an electrical gremlin?

What you describe has sometimes been a situation of low battery charge. If you let the car sit for long or don't drive very far each day (my total rd trip commute is 6 miles and not enough) there is enough parasitic drain that never gets caught up without a good 20 minute drive or so. I have a good weather car and the X3. When I take one out the other sits on a battery tender to ensure full charge even though I may not have driven the sitting car for 2-3 weeks. I used to get these two warning lights and since I changed to the battery tender process I haven't seen them in more than a year.

Oh, and I have not replaced the original battery either.
