    Hi Kyle

    Welcome to the forum.

    Lets get you set up for BMW ownership with a few links:
    - NewTIS for wiring diagrams and service information https://www.newtis.info/tisv2/a/en/
    - RealOEM for part numbers and exploded diagrams www.realoem.com
    - Have you got a good scanner with BMW software so you can read the trouble codes in all of the computers/module in your car? There are many options. Here are two

    INPA software (free) on a laptop with special cables (cheap) https://www.bimmerforums.com/forum/s...xperimentation

    Foxwell NT530 scanner with BMW software https://www.foxwelltool.com/wholesal...installed.html

    Once you have the scanner, read the trouble codes in the ABS module. They will point to the cause of your problem. Post the codes and the descriptions here and we can help you.

    Without the codes we are all just guessing and you will end up throwing expensive parts at the car in the hope of fixing the problem.

    There is only one thing more pleasurable than working on a Z3, that's driving it top down on a fine day.

    Good advice given, for there can be plenty of other things that you won't find right away.

    So let's go thru the codes then.

    280C, for that I would check the connector and the power supply, aka the fuses.

    I think all the other codes are related to the first one, for if the control module isn't communicating properly, it will populate all those other codes as well.

    Also I would clear all the faults and road test again and see which one comes back first

    I have a similar problem on my 2004 E46 showing 5E21 and 5E24 Trouble code, (Pressure sensor 1,2)
    Where is this pressure sensor and does it mean I must replace it?
