if you read that link it I put there it basically says BMW has 3 types of steering, servotronic witch is a electric servo driven hydraulic power steering witch is the standard engine driven hydraulic and active steering. the servo hydraulic is the one with the bad reviews. at least that is what I got out of a little research but i could be wrong wouldn't be the first time :iono:
