I have a 2014 BMW F01 (750d xDrive). It keeps pulling to the right and I initially thought the car needed an alignment. I got an alignment at a local shop, but the problem persisted.
I went to the BMW dealership and they began troubleshooting:
- They replaced MacPherson struts.
- Replaced the MacPherson mounting assembly.
- Did 3 more alignments.
- Changed from the summer 20" wheels/tires to the winter 18" wheels/tires.
After all of that, the problem still persisted. The BMW dealer couldn't tell me how we can fix it. I finally took it to a mechanic that worked on race cars and he told me that the angle on the (electronic) steering rack was something to the tune of 6 degrees off. He said that it's electronically controlled and he can't program it, because it might cause some other issues. He thought that the risk of other issues, and the potential cost of fixing them, is too great for the inconvenience of the constant pulling.
Any ideas on how this problem can be solved? Has anybody had this problem before?
