ATSG Bmw, Audi, Porsche Technicians Guide description of the catalogue:

This booklet contains information that has not normally been available in most OEM repair manuals and can be
used by the technician to diagnose electrical concerns, identify the location and direction of the valves, springs,
retainers and bore plugs in the valve body. This information has been prepared from actual valve bodies and in
some cases may vary from one model to another, but is invalueable when the need arises to diagnose and repair
electrical and valve body concerns.
