[s-cars] fuel gauge fixed

[Vincent Fregeac]

Not that I'm pessimistic by nature but there is a good chance your
problem is nature of the beast. I've seen a lot of cars with non-linear
fuel gauge - my S6 is one of them - and fuel gauge moving when you turn,
brake or accelerate. To avoid this last part, the gauge should be place
on the vertical line of CG of the fuel tank and even in this case, a
weirdly shaped tank could affect the reading when you're putting some Gs
on your car. A quick and dirty fix is a heavily damped fuel gauge so the
fuel gauge will not have the time to move when you turn or brake. It
seems to be the choice Audi made. My girlfriend's Saab read full tank
within half a second when you start the car when, on all the Audi - as
well as Honda and Mazda but not Mitsubishi - I've owned, you'll have to
wait 10-15 sec. to know what's in your fuel tank.

Congrats Paul!
I have a dumb situation that may need the same repair. Did you need a
special spanner to get the unit out? and I think the consensu was that
the
ski sack does not have to be removed?

My symptoms -- Upon filling (motor and cell phone off, of course) It
shows
full, then after a very short time (maybe 10 miles) the gauges drops off
to
7/8ths or so. It then stays there, but upon starting, may actually blink
and
tone the outta gas light. Next start it may show 7/8th again. It will
stay
at 7/8 and gracelfully go down to about 1/4 and then stay there until
the
fuel is all but gone (I think). Here's the funny part. When I turn
right,
the gauge noticeable will move down and when I turn left, it will
noticeable
move up (or was it the other way around). When travelling straight it
settles back again. This behaviour is very different from my 95.5, which
remained rock solid and read accurately till drop. Is this the sender or
should I try something else first. No other gauge problems noted.

Just a dumb update...

Story:  after replacing my fuel pump (in vain, no effect on my hard
start),
my fuel gauge would not read more than the high mark in the reserve
area.  I
suspected I tangled some of the in-tank lines around the long sender
swing-arm 'wire' thingy.

Finally got around to pulling it apart last night (like 2 minute job),
noted
the bulb for the sender was wedged against a 'lump' in the tank down
near
the fuel pump mounting area.  Ah HA!  Removed, replaced more carefully,
filled tank today, VOILA!  Gauge reads fine.  Finally Paul manages to
not
muff something up, well, to successfully fix something he DID muff up in
the
first place.

So, duh, be careful if you remove this unit from your tank... it's
replacement needs to be spot on (more duh), as the tank contains some
odd
shapes inside that the sender needs to clear.

Since I'm on fuel gauges... anyone have any thoughts as to why the gauge
won't read 'live' when I fill the tank with the car running (I don't
wanna
hear it tree huggin' hippies, YES, I fill my car with engine running!).
Even my f'n '80 Volvo or '76 Westphalia had gauges that would read as I
filled them.  F'n $50k Audi gauge acts 'dumb' until car is restarted?
Don't
get me started...
