I am simply sharing the information I received with the car.
My receipt from H&R Marty Neubauer states he installed a #1 442 200 058 on the advice from Gus.
That's all I've got. Yes, it's a mystery, that's why I'm making the effort to find out if anyone in this large forum can shed some light on it.
Here is a link to that # cam.
