I have an E34, USA. 1994 540i with 82,000 miles. The last couple of weeks I've noticed a deep "groaning" sound in the front end when turning at low speeds. It doesn't happen right away, but usually after
5 minutes of running. It even happens when I am stopped at a light, not moving, and just turn the wheel left and right.I am not a "car person," but am learning more every day since owning this BMW for a few months now. I suspect it's something with the power steering... Could it be that I just need to fill the fluid, or is it possible that the power steering pump is breaking down? Hard to say?
I know that BMWs require special transmission fluid... how about power steering fluid? What do you recommend? Thanks!
