4 lights on

plmbst · 08-31-2021, 01:51 PM

The warning lights first showed up a few days ago. They reset after restarting the car. They do not reappear until I put the car into reverse and travel about 20 feet.
The codes I retrieved via INPA:
-EGS 578E, 581A
-VGSG 54C6, 55C3, 55C6,
-RDC 604E, 605E
-DSC 5E26
The tire pressure monitor has been inop for about 6 months.
I have the BMW specific oil for the transfer case ( from years ago, I saw that fill plug location and got spooked) and am willing to give it a go after reading some threads.
My first concern is the multiple warning light scenario. I plan to check the LF speed sensor first, but yesterday I did reverse three times and got no lights. The lights, so far, have only activated when reversing.
I‘d appreciate any thoughts/ideas.
Thanks,

ETA: The lights do not show up every time after reversing.
And, can INPA be used to reset the transfer case after a fluid change?
Thanks again.

Just to put an ending on this thread, my LF axle had an out of round reluctor ring that triggered a speed sensor fault resulting in the myriad of warning lights. The fix was a new LF axle and new speed sensor.
Still need to do transfer case fluid change, though.
