SOURCE: BAS ASR problem

ok, first you have to clear the codes.
in this type of cars you cannot clear codes with a regular obd II it has to be the factory scanner or similar. after you clear the codes drive it for a while. when light comes back on scan it again and that is going to be your true problem. if you replaced the switch but didn't clear the code the light will be still on because the computer doesn't know that you fixed the problem. so try it out and let me know if worked.

SOURCE: the ABS ,BAS& ASR lights keep coming up

ABS--BAS

Most likely cause is the 'stop lamp switch'
It is a electric switch located on the brake pedal inside the car, about half way up on the brake pedal.
Pretty cheap too, I think the switch is only like $25 bucks.
2 connectors on the switch and then it turns out.
hope that helps

SOURCE: What does the BAS ASR light mean in a mercedes

brake light switch ,that's the part you need to replace to fix that BAS/ASR light. It's a $20 US part, a screwdriver, and 15 minutes to fix.
