I have a 2011 Countryman All4 S with 93,000 miles. Last week the DSC and AWD warning lights came on and stayed on. Today I pulled the codes and it shows
5E83 - DSC: Insignificant CAN fault: delete fault memory
5E88 - DSC: Hydraulic unit, pressure sensor: internal

Anyone have any idea of where the issue is? My best guess based on all of my research and with an understanding of the parts associated with the DSC is the hydraulic pump. That would align with the 5E88 code.

i took the car to the BMW shop last week and after running diagnostics (though I’m not convinced they did everything they said they did) they said that the DSC hydro pump was bad (which I had recently replaced). So I ordered and installed a rebuilt unit. Once the brakes were bled and the calibrations were complete, what pops up, the same 5e83, AWD control coil open, code. So, at this point I’m lost as to what to do. The shop claims they checked all the wiring/sensors, though it doesn’t look like any of the underside shielding was removed which would indicate they prob didn’t check the wiring at the rear diff.

Any my new ideas from anyone is appreciated!
