Hi,

This happened to work for me by chance, not saying it will works for everyone else case.

So, i had the dreaded issue with the three lights that identify an issue with the ABS system, the usual is the wheel speed sensors, pressure switch or the most costly the abs module under the passenger seat.

i had changed all the wheel speed sensors along with my bearings, didn't work. i changed the pressure switch my code reader was showing, still didn't solve the issue. went away on holiday and my car battery kept dying. found out that the issue was the light in the centre console didn't switch off draining my battery so i took the light out, I'll replace the switch one day.

i lived with the issues for a while where i jumped the car before going on a drive on the weekends. Eventually I replaced the battery and the issue with the ABS was gone. drove a few hundred miles now and it hasn't returned.

What are the chances that the rubbish battery was the issue all along?
 
I've highlighted this elsewhere.
That light is operated by a tab on the bottom of the access door pushing on a microswitch.
If the tab breaks the light stays on.
You can remedy this simply by fitting a small self-tapping screw into the bottom of the door, to operate the microswitch.
Easiest with the door out, and make a small pilot hole first with a drill to prevent cracking the plastic.
