If a hose is in the way (can't remember off hand), disconnect it and connect it to the new N75 right away after installing the rubber mount.

Try unplugging it and cleaning the connections, delete the fault codes, and see which fault codes come back. Audi A4 B6 Tdi. Skoda Octavia "down and out". S.
