I have been looking at this problem for a while now.

2004 545i with active steering and dynamic drive.

Keeps showing an annoying check control message saying that "stop vehicle, loss of fluid in dynamic drive" Will get correct wording in morning.

anyway no faults for DSC, or related to dynamic drive. this will not go away and car seems to drive normal, fluid level is correct, and fluid is clean.

I orginally thought the sensor for fluid level was at fault so i changed that, along with reservior no change. Cannot locate wiring schematic for the level sensor to chase the wiring.

anyone have the schematic?
