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.Any time any of the warning lights come on including the APV light this means the computer system is seeing a system fault and when this happens the computer will set and store a fault code and or codes. In order to determine what is failing the first thing you are going to need to do is to have the computer system scanned to see what the fault code and or codes are that should be setting. If you can get this done and post back with the results we can work from there to help you get this resolved.
