Last week my 2008 E70 iDrive screen began warning me of an ABS system problem. When I ran the Carly diagnostics, it came up with fault 93C6, which seems to be the back rest lock of the driver seat. Low and behold, none of the driver seat controls work any more either. Looking for suggestions on where to look first, as it seems that the indication is related or directly resulting from the seat controls going INOP.
