Sorry to hear about your troubles. EPS stands for Electric Power Steering, but there're electronics involved, of course. It's a shame that EPS is becoming the PS method of choice (even for BMW), but I saw it coming on small cars due to being much cheaper than a hydraulic system, and a noticeable fuel economy advantage on small engines. All 3-series BMWs (except current M3) are using it now, and that's exactly what ALL new 5-series have, with the excuse it was needed for their optional 'parking assist' in some models. I wonder how reliable it's going to be, but at least we have 5 years of warranty on that (wish it had the 10yr/100K warranty though). Please keep us posted. You're the second person to report a problem. The other guy has a screeching sound and was told to wait until 12K miles to see if it goes away. You did much better :thumbsup:. Take care.
