This is on my E39 before, but I think still relevant. I had the trifecta pop up twice before and 1) First time it was indeed the ABS module. 2) The other time this came up it was due to the ECU cable that was near the back of the engine block that feeds steering and speed data back to the ECU. It's supposed to be clipped properly but the idiots at Dinan I believe had not clipped it properly after the valve cover gasket. Long story short, the wire insulation was touching part of the heat shield and was exposed.....so a bad cable issue.
Dinan resoldered the cable (although I should have pushed them to replace) and problem resolved.
If it's the ABS module, then sending it BBA reman is the way to go. Much cheaper than buying a new module. Just take it out and ship it to them and you'll get the fix back in less than a week.
