That's exactly what it is. It has the VW brand on it,
but it was made by Grundig.

There is a dial on the box with 16 positions.
Positions 4-11 "check the following functions of the
control unit:
4 - Engine speed correction, pump control
5 - Basic compensation, rich
6 - Basic compensation, lean
7 - Engine speed correction, full load enrichment
8 - Acceleration/full load enrichment
9 - Start & warm-up enrichment
10 - Pump control
11 - Pump control

The manual says if any of these tests fail, the
control unit is defective and should be replaced.
