My w120 s class 420 1994 Mercedes ABS and ASR light comes on when I back up or make sharp turns why?
When the car starts up it runs fine. As soon as I make sharp turn of back the car up the
ASR and ABS warning light comes on but this happens when it 80% or hotter or its
extremely cold weather (0-).
Sounds like the wiring going to one of the front wheel ABS sensors is bad. These wires are prone to wear and breakage because they're always moving and flexing when you turn the steering wheel. This is being further exasperated with the heat. Heat causes things to expand and can make a questionable connection come loose. HTH. -Jim
