This mallfunction message came up. So I took the car to the dealer and his computer said it was the right rear speed sensor. It looked damaged so replaced it. Still getting same malfunction message. Computer then stated brake light switch which was replaced. Still getting same malfunction message. Computer said brake pedal travel sensor. It was replaced. I am still getting the same malfunction message and have spent over $600.

Has anyone else experienced this?

My car is a 2003 S430 4matic.

 

could be stop lamp switch??

 

Stop light switch has been replaced. Brake pedal sensor has been replaced. Right rear speed sensor has been replaced. Battery has been replaced.
We are not knowing where to go now.
