Your documents are FANTASTIC to help me understand the system!

All cross referencing indicates I do have the Bosch 5.7, including those references in the documents you posted which explain how the whole Bosch 5.7 ABS/DSC system works with the sensors.

Others will benefit also! One way, if we can figure it out how to do it, to test this front-brake pressure sensor would be to do a "flying lead" while the car is running to see if a 0 to 5 volt signal is generated while using the brakes.

But, it would be easier to do a static test of this front-brake pressure sensor with the car ignition off from the ABS module connector.

Do you have any ideas how to test the "offset" of the front-brake "pressure sensor" that is screwed into the rear of the ABS hydraulic module.
