Did process whole car. Figured out that little trap early.

The lines that went missing are:

SW_I_SERVOTRONIKANSCHL_C wert 02
SW_I_SERVOTRONIK_C0A wert 04
SW_I_SERVOTRONIKANSCHL_C wert 00
SW_I_SERVOTRONIK wert 05

A 1M has the same JBBF and much the same options as a 135i so I would think that it would be a smooth operation. Also a 1M has only one servotronic setting whereas the M3 has at least 3 that I am aware of. I am not sure how heavy the steering is on a 1M even with servotronic so it is difficult to get a fix on what final result should be. As I said the weight is not unacceptable as it is if disconnected.

I do know that the voltage I am seeing is variable and not according to road speed and if I disconnect the cable the steering goes heavier and a servotronic fault appears. Also interesting with the ignition turned off there is a residual 3.2v running to the valve.

I am pretty sure this is a software installation issue.
