2007ml350 speedometer doesnt work. little background i got this car with smashed front end. I replaced bumper, hood, front clip with used. before i replaced anything the car still drove and everything worked. the two sensors that go in the front clip next to headlights im not sure if i used the ones i had or ones off of the used clip. i get codes of my generic scanner (0925 CAN signal ' Vehicle speed at front axle' from control unit Traction systems is implausible. (p2158)
ALSO No CAN message was received from control unit Traction systems.
ALSO C121 No CAN message was received from control unit N47-5(ESP and BAS control module)(171/203/209) or from control unit N47-5(ESP control unit)(164/219/251/216/221) or from control unit N47-5(ESP,SPS [PML] and BAS control unit(211/215/220/230) or from control unit Brake system ALSO D139 No CAN message was received from control unit N80(SCM[MRM] control unit)
ALSO 062F Component Y3/8n4(Fully integrated transmission control (VGS) control unit) is defective
Would me placing the wrong sensors back in place cause all of this. I replaced front speed sensors in axles that didnt fix anything.
I cant seem to attach the pics but numbers on sensors are:
0038202926
965 031106
132 403030
Q01

Could this be a relay or does anyone know where to begin?

thanks
