Oh good about the RDC. Thanks for checking about the ohms.


The part number I was curious about earlier was actually for the servotronic solenoid or valve rather than the pump. For some reason I haven't found any part number indicating an application to E83 yet.

In another forum, I'd read something about a "9V battery" test applying power directly to the servotronic solenoid on the steering rack, but peple were hacking their harnesses to do it. Tempted to try 0V vs 9V through the connector while the glovebox is still apart just to see if there's any difference in actual assist, but want to be reasonably sure it won't fry anything before proceeding...
