Tips & General Notes
Use
the ‘Find’ function (CTRL+F) to search for electrical
components on this page.
Left-Click
to open schematics in this window, then navigate back to this menu for a
subsequent selection.
SHIFT-Left-Click
to open schematics in a new window.
Right-Click
and select ‘Save As’ to download schematic diagrams.
Also - Be advised that, despite these schematics
being in English, the sense of ‘driver side’ and
‘passenger side’ is often (though not always) intended for LHD
vehicles. Some diagrams use left and right convention instead.
All
original schematics have been captured as black/white images at 400dpi for
a good compromise between compact file size and suitably high quality when
reproduced on paper.
Please
contact s2central@mac.com if you
discover or suspect any mistakes.

Basic
Equipment
Special
Note for this model and year – The basic equipment overlaps with the
Audi Coupe fitted with 5-cylinder engine, coded NG. The basic equipment schematics for this, and ABY-engined
vehicles, make reference to the Mini-Check module within the instrument
cluster. This is slightly confusing as the S2 was fitted with Autocheck as
standard equipment. See further notes embedded in the tables below.
This link retrieves the complete basic equipment
schematic for the NG equipped Audi
Coupe as a multi-page file.
This link retrieves the entire ABY Motronic schematic, for this model year, as one multi-page
file.
The
table below is organized into single sheets for easier access to basic
equipment.
