Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The ABS light is coming on because the ABS system is seeing a fault and until the fault is repaired the light can not be reset. In order to determine what is failing you are going to need to have the system scanned and the fault code and or codes retrieved. When you had it worked on before did they give you the fault code and or codes and if so can you post back with it . If I know what the fault code and or codes are I can help you determine the cause.
