Having problems with your Mercedes-Benz C-Class ?
The abs light stays on when car is first started you put the car into drive it will not change out of 1st gear even once the car is warm it makes no difference it will not change gears .to get it too function properly i have to pull over turn the engine off and re start it
The only way to know what sensor has failed is to get the code to proceed. There is a good chance the wheel speed sensor failed but since they are not cheap getting it diagnosed properly is the only route to go. there are 3 options, a failed speed sensor, a failed ABS module, or wiring issues. guessing really isnt an option since the code is the most direct way to get to the cause.
