Persistent ABS/DSC System Issues and Cruise Control Failure in BMW 7

I'm experiencing recurring issues with my BMW 7's ABS/DSC system and cruise control. Despite attempts to erase the errors using an ISTA system, they persistently return. This has also affected my cruise control functionality. Most BMW service centers have refused to assist due to my self-maintenance approach. Live data shows my wheels functioning correctly, but the ABS unit doesn't seem to recognize it due to my inability to reset the maintenance. I'm also getting faults from over 100k kms ago and others projected for 200k kms in the future. Has anyone else experienced these issues and found a solution? Any advice on how to reset the maintenance and resolve these persistent errors would be greatly appreciated.

It sounds like you're dealing with a complex issue. The ABS/DSC system and cruise control are interconnected, so a fault in one can affect the other. It's possible that there's a problem with the ABS control module itself, or a sensor might be faulty. Firstly, I'd suggest checking the ABS wheel speed sensors. They can often become dirty or damaged, leading to incorrect readings. If they're fine, you might want to consider having the ABS control module professionally tested or replaced. Remember, these systems are crucial for the safety of your vehicle, so if you're not able to resolve the issue yourself, I'd strongly recommend getting a professional mechanic to look at it. Please let us know how you get on with these checks, or if you have any further questions.

Thank you. I've changed the sensors several times and they show the right values. I need to have a replacements registered in the car, but that's the problem. BMW refuses to do that, cause I changed the pieces myself. Brake discs, pads, sensors, suspension, you name it.
