The web site at car-part.com uses the Hollander Interchange Manual - that
gives you a fair idea of which parts are interchangable from certain cars -
like the alternator in a VW Jetta into my '87 5ktq (ok, easy example, but
HOWEVER, the interchange is not always right - Audi changed things often,
and often previous owners might have "hacked" parts to make them work -
ECU's often differ with same engine codes - like 1 or 2 knock-sensor MC
engines. It's often best to take the number from the part in your car, and
call the yard to make sure their's match.
A while ago, someone on Audifans ran down the number of electric motors and
servos in a Type 44 - the number came to around 20-some. There are control
units for many of them - among which are: a/c control unit, ABS control
unit, Engine control unit, seat memory control unit, cruise control unit,
etc. etc. etc. The Bentley manual gives a rundown of what is located
where - yes, the ABS is under the back seat, and in my '87 5ktq the thing
behind the hood release lever is called the "Kostal Connector" where the
wiring harnesses from the various parts of the car meet together. The
Bentley manual has decent wiring diagrams that you can trace faults
through - BTDT recently to fix a problem I've been having with intermittent
dash lights (temporarily fixed by putting the correct wattage bulb in the
driver's side license plate light - who knew?) - make sure that you check
the fuse panel too - nothing worse than tearing into the dash just to find
out that it's a fuse that's burned out.
1987 Audi 5kTQ - is there supposed to be 7 volts coming from circuit 13 into
circuit 14 with the ignition switch on? not sure about that one...yet.
1980 Audi 5k - born with a/c control unit sensors in my skin
1962 and '64 Auto Union DKW Junior deLuxes - 2 electric motors (starter and
windshield wipers) - what bliss....
