Dynamic Drive Malfunction Light
My 2004 530i has developed a strange behavior. After a four month storage interval, on startup I got the Dynamic Drive Malfunction light, then it went out after a few miles of driving. The next day, got it again, and then the next day got the Dynamic Drive Inactive light. Again, it comes and goes. I have checked the power steering fluid, since I understand it uses the same fluid from the same reservoir for the dynamic drive. Now several weeks later, one or another of those two lights will come up, stay awhile, and then go out. The maddening thing is, I used my Bav-Auto code reader, both while the light is active and when it is out, and there are no stored codes! Zero!
This car is the I6, and has 130,000 miles. Still runs like a charm, and looks brand new. Sure would like to get this thing repaired, or at least figure out if it's the computer messing up or the active drive system. I do not detect any appreciable handling changes when the light(s) are on. Any help out there?
