BMW X6 E71 N57 Steering hard intermittent

[BMWFans21]

Dear Family,

I have a BMW X6 E71 N57 2012, very strange problem with no DTC at all. With the original solenoid on the steering rack (picture attched), the steering is super soft while on P, driving but can be hard at anytime at any speed. As i mentioned before no DTC at all. Wirign from ICM to Eco Valce (Solenoid) is good.



I put a new one VEMO, and now the problem change. On P the steerign is super super soft same as the orignal solenoid. As soon as the wheel start to rotate 1 km/h (either on D or N) you need to apply a force to turn it. After it reaches 60km/h it start to become more soft. Scan car no DTC.

Thanks
