2007 BMW 540 My ABS, braking, and traction control lights are all illuminated. First, I attempted the low-cost fixes: a $15 brake light switch and a $80 vacuum sensor on the outside of the ABS unit, both of which are potential causes of the dash lights.
According to everything I've read. Every path leads to a malfunctioning ABS module.
BMW wants about 950 for the item, which will then need to be programmed into the car. Used ones are around $300, but they still need to be programmed; hopefully, you can repair it.
