I have a 91 525 (recently purchased) Starting to flash warnings on dash eg. low coolant level, brake light circuit, and suspension leveling. I have had all the bulbs checked (brake light circuit) and not one of them was bad?? The coolant level is right where it should be and Im not sure yet on the suspension leveling warning, but I wonder if there is something Im not checking on these things (brake lights/coolant level) or could I be having problems with the obc or ??? Any ideas would be greatly appreciated.
