1991 318is 140k miles.
Tonight when I was waiting the traffic light, four lights: Braking Fluid, Park Brake, ABS, and Battery were all on. ABS is yellow. The other three are red, but not bright red. The park brake light becomes brighter if I push up the hand brake. The car can drive without special symptoms.

Why did all these lights suddenly show up? I have done nothing on this ca related to this indicators. One problem I know is the coolant temperature sometimes goes up to the red area.

Thanks a lot for any input! anxiously wait for replies.

Did you check the voltage from the battery or the alternator?

When I owned the same car like yours, the alternator was failing and the battery voltage was low, causing alot of the dash warning lights to light up.

Thanks, Cohiba. I checked the voltage and the alternator didn't provide proper voltage. I put it in a shop that also checked it for me. The alternator was bad. I don't know if all the lights will be gone after the alternator is replaced. Hopefully it will do. I will post it up afterwards.

Just a follow-up. It is the alternator problem. I changed it and all lights were gone.
