This page covers the electrical spaghetti which is located under the dashboard on the drivers
side of the car on a RHD model. There is actually a relay plate with 3 rows of 6 positions under there,
although it can be hard to tell as often the wiring has been disturbed by dubious alarm and immobiliser installations.
By removing the parcel shelf from under the steering column, you will see a mass of wiring and relays. On the reverse
side of the parcel shelf, there is an illustration in German and English like this one
here. Sorry about the quality which makes it unreadable but it's barely readable
with the naked eye.
The relays are numbered from 1 to 18.
Top row positions are 7-12.
Middle row positions 1-6.
Bottom row positions are 13-18
The table below outlines the relays and there functions with each postion being a link.
Note that not all cars will have every relay fitted. On my own car,
there were only 5 out of the 18 possible positions filled.
I apologise for any inaccuracies on this page. The electrical wiring had numerous changes during the production
of the Audi S2 from 1990 to 1996 and I have attempted to cover as many of them as possible. If there is a glaring error,
please let me know and I will rectify the offending mistake.
