Thanks to Jim and Steve for the replies.
I have sorted the electric aeriel. A most surprising outcome. After all my
testing and re-testing I found that the wiring of the two-pin connector that
supplied the power to the aeriel (red/black and white wires) was wired the
wrong way round. I removed the two wires fom the plug, reversed their
positions and it works a treat. Which means it was either incorrectly wired
from new, someone had messed with it previously or the original radio had
its terminals the other way around. Anyway, it is sorted now.
Thanks for the help on this one.
Re: the sender in the bell housing - I guess it is like the injectors seals,
the o-ring has hardened making removal difficult.
Re: gearbox and ratios - thanks for the information.
Re: the pressure sensor in the ECU - I will speak to Roger when I see him
next but if his chap is repairing them it must mean that somewhere there is
a manufacturer who makes a transducer of same/similar spec that can be used
to replace the hitachi product.

> After a fairly long period without posting I now have four questions:
> 1. Aerial Wiring: I have been fortunate and obtained a fully working
original electric aerial for my WR. The wiring feed to it appears to be a
two-wire T-shaped connector with one spade connector set at 90 degrees to
the other. The top of the "T" is a red and black wire which appears to be a
permanent live (from where I am not absolutely sure but a continuity check
suggests it comes from the radio - but perhaps changes colour on the way).
The vertical of the "T" is a plain white wire which definitely comes from
the Radio and seems to be the "trigger" feed from the radio (I know this
because I have tested continuity of this to the multi plug on the rear of
the radio. (I call it "radio" but it is a Blaupunkt CD & radio). When the
t-connector is connected the aerial will not lift or retract when the radio
is switched on. Nor if the ignition is switched on. Makes no difference.
> If I touch the red/black wire on the "aerial" terminal for the white wire,
the aerial lifts. If I touch the red/black wire on both terminals
simultaneously, the aerial retracts. But if the two wires are connected as
they should be, nothing happens.
> Does anyone know what is going on and how it should be wired and should
> 2. I have a spare ECU which has the pressure sensor outlet "stump" broken
off. Does anyone know a supplier of this sensor (transducer) and if possible
a part number or value/rating. Approx cost would be welcome too.
> 3. Can anyone point me in the right direction for a chart or the like to
show how to identify the various ur quattro and coupe quattro gearboxes. I
have an 016 gearbox that came from a one owner from new 1986 coupe quattro.
I also have what I was told was an ur quattro 016 gearbox. In almost all
aspects they seem identical (only difference I have noticed is one box has a
switch in a different place where the other has a blanking plug and vice
versa. Is there any way to tell what boxes I have, and what ratios they
contain. I always believed the coupe quattro was lower geared than the ur
quattro to give it a bit better accelleration with its lower powered engine.
If true then it will be no use in the ur quattro.
> I know that the numbers on the top of the bell housing will tell you when
a box was made - i.e. 20106 is 20 October 1986 but I would like to know more
and ultimately confirm what I have in these two boxes.
> 4. Finally, the sender that sits in the hole on the top of the bell
housing - that looks for the pins in the flywheel - how do you remove it
without breaking it. I have removed the cap screw and it is possible to
rotate it in either direction but I can't lift it out. Any good suggestions.
> I will be grateful for answers to any or all of the above questions and
will look forward to reading the.
> Many thanks.
> I guess you can tell from the length of this email that there isn't much
to here because it's STILL RAINING here in sunny (a long time ago)
> Have a look at the galleries attached to these links if your interested.
We have had a bit of bad weather here recently to say the least.

out of their homes.
