I HAVE A 1997 C280 THAT WON'T SHIFT OUT OF FIRST GEAR. THE CODES ARE 0017 SELECTOR LEVEL CODING INVALID AND 0113 SPORATICALLY SELECTOR CODING INVALID. DOES ANYONE KNOW IF YOU HAVE TO REPLACE THE WHOLE GEARSHIFT ASSEMBLY TO FIX THIS OR IF IT IS JUST THE RECOGNITION SWITCH?

 

if the cables or connectors are loose, it will store the fault as invalid coding.

check the cables and connectors first .

also check the shift rod if it was correctly adjusted.

only then that you can change the GEAR RECOGNITION SWITCH.

 

I replaced the switch and it fixed it.

Thanks,

Andrew
