Suddenly my 99 E300 is tossing up an error message that takes over that display space on the dash, saying "B-A-S", and "A-S-R" appears in a little window on the lower left corner. This is the first time I have ever gotten an error message about the braking system in any car, let alone an MB. Of course, the manual says to take it to the dealer, and also that it is OK to drive. Any idea what I am in for??? Could it be a speck of dirt lodged somewhere inconvenient to a sensor of some sort? :confused:

Message appears whenever battery is disconnected.

Also can be defective brake light switch.
