Which workshop manual came in 25 volumes? I have some Bosch workshop
manuals for the D-Jet that comes in multiple volumes, each one for a
different make of car. One volume covers 311,411, and 914
D-Jetronic.

The early Bosch tester was the EFAW 193 S 10. It had two rotary
switches arranged left/right. It could be adapted to the late cars
with the Bosch EFAW 243 adaptor: I have never seen one of these.
The late bosch tester was the EFAW 228. It had two rotary switches
arranged up/down. This is the one I have. It is shown in the 1972
fourth edition of the Elfrink FI tech manual. Volvo, Porsche, and
M-B came out with D-Jet cars in 1970, I think.

Are you referring to the three light tester? Interesting. The three
light tester is shown in the Bentley manual, VW 1218, pg 4-21.
A part number ASE 000 050can be made out on the front panel in the
photo.

This sounds like my Bosch manuals.
