I have an E39 540i and I've just bought it well maintained and enjoying it, this morning as I was driving to work my traction, ABS and Brake light came on and won't go away. What could be the problem and how can I fix it?
Search this forum for "trifecta" and Google search "e39 Trifecta".
You will find all the help you need

I recently got the trifecta after my car had been pretty much sitting for a month. I had to reset it a few times with INPA over the course of a few days, and it hasn't come back in the 3-4 weeks since.
You should still research it though.
