The problem I am having with me 1999 ML430 is that if i start truck and just turn wheel all the way one way then the other way the brake light will come on and beep and truck will go into limp mode.
Also if im driving down the road same light and beep will come on and truck will go into limp mode but lets say if im in 3rd gear it will stay in that gear.
I had the truck scanned using a scanner that was not a OBD2 and was not at Mercedes. Gave me a P0720 code. Rear speed sensor.
But you would think i would have to be moving to make it go into limp mode. Not by just turning the wheel back and forth.
I am guessing that if I get it scanned at Mercedes it'll give me a lot more detail.
Thanks. Jay
