Ah, this explanation helps. Thanks. Sorry for not knowing this ahead of time. This errant sensor reading might be the reason some people replace sensors and the ABS module yet still have the three warning lights lit.

It seems there is a "pressure sensor" P/N 34511165467 $111.68 screwed into the back of the hydro unit in the engine compartment of the 2002 E39.

I wonder what an "offset" error indicates?

Any advice how to test this ABS hydraulic unit "pressure sensor"?
