The headlight switch is part of a complete switch assembly that includes
the lights, turn signals, cruise, and the emergency flashers. The assembly
is riveted together with brasss rivets, and when I broke my headlight
stalk, after a temporary ( 5 or 6 weeks ) patch with epoxy, I sprung
for $120 or so for a brand new replacement from Shokan. I was not
a net member then, and only tried them for prices ( MUCH lower than
The switch assembly is easy to change, and if you attempt to
repair it, it may be quite a challenge to dismantle it and bolt it
back together. I was in a hurry to get the car running again, so
I took the SURE way out.
The relay mentioned was purchased from J.C.Whitney for $17.95, it
was a dual relay, and included internal fuses all in one metal box.
I was un-impressed bt the quality, and so did not recommend it further,
but since I had already paid for it, and it was in my hands so to speak,
I installed it anyway. My backup position is the way I wired up
the lights preserves the original headlamp connectors, and I just tap
into them. If the relay fails, I can be back to the original AUDI
wiring in a few minutes.
Now, while I'm on the net........
1. I changed my front left CV boots over the weekend, I could not
dismantle the out-board joint like I had planned, so I rented the
"wheel puller" tool, and got the drive shaft separated from the
wheel hub. By the way, the tool to open the in-board joint is
the 10mm 12 point bit. NAPA did not have the tool, and I tried
to describe it as a 12 pointed TORX. The salesman brought out
all the torx, and got pretty upset when I told him that it was'nt
a torx, but "something like a torx" ... ("why the hell did you
say it was a torx in the first place")
Dismantling the outside joint required SERIOUS hammering with a
mallet all the while holding the infamous CIRCLIP open
Boy, was there TONS of grease all over the place.
2. Also changed my thermostat, very easy to do in principle, but
requires a contortionist with very small hands to be able to
reach in and loosen up and re-install the two 10mm bolts.
3. My friend, the Account Manager from Locktite, told me to soak
the O-rings in a silicon based lubricant, and then make sure
nothing moved while I put the two half sections together.
In short, he thought it was POSSIBLE to sucessfully replace
the seals....( O.K. Bill ..... I know what you are thinking
while you read this...).
