Hello I own a 2010 X3. I Recently replaced my steering angle sensor and had it programmed by bmw. It was the original problem I was having. the abs and 4x4 and triangle light were on. It fixed it. Now I noticed under hard acceleration or hitting bumps the 4x4 flashes and it doesn’t activate the abs but it feels like the front passenger wheel is slowly getting locked up like the brake slowly getting engaged (or loss of power). I replace all the wheel speed sensors. I checked the gear in the transfer case and it looked brand new. I also replaced the transfer case oil and recalibrated it with ista+. I noticed a rear spring was bad so I figured the wheel hop causes it but that was also replaced and it’s still doing it. Does anyone have idea of what’s going on???? I’ve tried practically every solution I could find
