E93 n54 warning light issues - help

[Friedmike]

I have a 2007 E93 N54 that has been running worry and warning light free for some time. However, last week, three warning lights all went on at once. The ABS light, the BRAKE light and the TRACTION CONTROL light. I’ve checked the codes using both a generic and an Altel reader. Here are the codes: A731 - JBE, 6054 - RDC Left Front Wheel electronics, 6057 - right rear wheel electronics, 2E8D - DME Intelligent Battery Sensor, AND 2AAF - DME Fuel Pump Plausibility. I reset the codes and they came back a day later. Then the next day they were gone and came back for two days shortly after. Gone again and on now. Has anyone experience anything similar and have any ideas what it may be? I’ve tried the steering wheel calibration that some people recommended and that didn’t do anything. Battery is showing 14.1v. Looking for some recommendations on where to start troubleshooting. Thanks!

I hate those intelligent battery sensor. Have you recently had your battery removed or replaced? A failed/failing battery has done this before on a BMW at my brother in laws shop (Manheim Auto Auction in Ocoee)

With the cold weather snaps we've been having in Orlando lately, I would start at the battery

Did all the faults come back? Generally the abs traction and brake light come in because of faults in traction control, the reason the other lights come on is because the signal from traction control is send to other systems in the car so if the signal or information is faulty other lights pop on.

This happened on my E39 and it was the wheel sensors on the traction control system. Had it looked at in the shop and they was able to tell me which wheel sensor it was. They replaced it and no more lights.
