Greetings,
I am now working on my £700 project, and I am waiting for my buddy to arrive so that we can do a thorough examination of the wiring in order to determine the cause of the OBD connection failure.
Regardless, I am seeing a persistent illumination of the ABS, DSC, TPMS, and handbrake warning lights.
The Dynamic Stability Control (DSc) fails to function when the button is pressed for a duration of 5 seconds or more, or when there is no discernible impact, resulting in the malfunction of the Anti-lock Braking System (ABS).
The warning lights remain illuminated consistently once the engine has been started, rather than exhibiting sporadic behaviour as often reported by most individuals.

If the rain does not occur, I want to remove the sensors from the rings this afternoon. Should I delay and attempt to repair my On-Board Diagnostics (OBD) system, or is it the Anti-lock Braking System (ABS) unit that is preventing the OBD from establishing a connection?

My hypothesis is that the valve in the ABS pump is the issue. This is the second time I have had this problem in a span of 5 years with the same vehicle.
Initially, I acquired a reconditioned pump, and subsequently, I obtained a pre-owned pump, both of which functioned well.
Simply replace the pump while retaining your module, without requiring any coding.

I neglected to mention that I am still able to establish a connection between the OBD and the ABS.

[David_Smith2003]

Frankly, I am now working without sufficient information till I resolve the obd. Contemplating the disconnection of all the modules in order to identify the cause of the connectivity issue.
Are there any instructional guides available for replacing the pump, or is the module located under the dashboard?

Is there electrical power available at the OBD port?

[David_Smith2003]

I have really conducted tests, but, I have not yet evaluated the resistance via the k line. I am uncertain about the specific outcomes I should be targeting when doing the test. The majority of the tutorials available are focused on an on-board diagnostic system that relies on a controller area network (CAN) bus.
The voltage passing through the k line is merely 1.5 volts.

The pump is equipped with a black box module.
My item was fastened with just two screws, but others may be secured with four.
The video is not an exact representation of the automobile, but it provides a general understanding.
Extraction of the pump

[David_Smith2003]

Thank you for that. I will attend to it as soon as I get the opportunity. I am concerned about the occurrence of bleeding in the absence of software.

[BMW_Fan2020]

I performed the bloodletting procedure using traditional methods, with the assistance of my wife.
Due to my restricted mobility, it takes me much more time to move about. Therefore, I decided to use this method and had no difficulties all.
One action I performed was to replenish the fluid and thereafter waited until it began to flow out of the pipes connected to the pump before securing them.
Uncertain of its efficacy, but the bleeding process proceeded smoothly with the application of pressure from a human foot on the pedal, amusingly enough.

I doubt that the woman is competent, and the outcome would likely result in a silent and uncommunicative meal.
