After 2 years the same problem has recurred with the same error message.

I'm not sure if this is a sign I need a new BCM pump but today I took out the pump and cleaned the connection again. There was significant dust and fine specks of debris inside the connector.

Doing this a 2nd time around was faster. And I took a few pics

It's best to remove the long bar on top of the engine. And the engine fuse box need to be removed and pushed away. Don't forget to disconnect the battery first

With those away you will have an easy access to the pump.

First 3 screws for the ABS bracket need to be removed. Then you can move the whole module a little bit to get to the 2 torx screw securing the pump

This is a pic after the pump removed. I have cleaned the area already

I've been searching and so far it appears the pump only comes with the module. Does anyone know if the pump can be brought separately? And who makes these pump?
