Rodg1350 0 Report post Posted March 26, 2013 Hi I have a 2005 530msport and the power steer has a whistle...very annoying. Happens mainly when warm , goiing straight and putting load on..squeeks !! I have changed the p/steer tensioner pulley because the belt was riding up abit and slight bearing noise. Also changed fluid (used the correct fluid from BMW). Probably just leaves the pump or rack and pinion steering...expensive ! Any ideas ? Thanks Roger Quote Share this post Link to post Share on other sites
