W211 - Distronic visit workshop, code related to bad communication with transmission
ive been getting the ”Distronic visit workshop” message on my dash and in turn cant use speedtronic either.
checked for codes via xentry and no codes related to DTR at all. Tried accessing DTR but with no luck as i get no communication with the control module at all.
could the can-buss errors disconnecting communication to the EGS cause DTR malfunction or am i crazy?




There are a few components involved when using distronic.
Not sure what model year you have. Can always get out the multimeter and test the connections shown below.
