I know we are all passionate about our Bimmers and it gets us in trouble as we sometimes expect perfection, however.... Ever since I got my torsion arm replaced in my 04 530i I have experienced vibration in the steering wheel. It happens at idle and when driving. no engine lights on. I am thinking that it has to do with engine mounts. Its driving me nuts, while its not a huge vibration, I hate it. Any suggestions... Do you think they forgot a grommet or two. They actually replaced one engine mount but that did not make any difference. Please tell me I am not going nuts!
