Help. Red brake light, dcs, and abs E53 4.4i

The car seems to drive fine. Scanned with INPA and here is the fault:

Anyone have any ideas?

Sounds like one of the ABS sensors has had it's cable unplugged or torn out. Check each ABS sensor connection - there is a small plastic junction box in each wheel well for the sensor connection (green arrow in this pic.).

Ok I plan to look the car over tonight. The analog redout of the wheel sensors in inpa all have a uniform readings. The fault talks about the rate of rotation sensor, ive read this might also be the yaw sensor. Thanks for the help

Yes, I've also read some stuff that infers that the rate of rotation sensor is the yaw sensor but I suggested the ABS sensors first as they are easier to check. Sounds like you have eliminated those via INPA, so yep - next check would be the yaw sensor. I think it's under the centre console, below the rear cup holders etc.
