[Vwdiesel] Vwdiesel Digest, Vol 54, Issue 8

If it was like my 90 Jetta, it only happened in cold (below minus 10 celcius) weather it was noisy and jumpy, it solved itself after the car warmed up or warm weather, I didn't bother fixing it yet, but I would assume it would be the cable and/or the gear in the speedo is in need of lubrication.
  if the speedo is loading thee cable the gear would skip, or if the cable is sticky inside, it could twist in itself and vibrate.

So I still have the intermittantly noisy speedometer. 
I have some more observations that may help in
diagnosis.  It had been quiet for some time, but this
morning squealed on the way to church.  (But not on
the way home.)

First, it was suggested that a bad motormount could
cause a pinched cable.  Well, I did have a bad front
mount, but that was replaced this week.

When it was doing it this morning, I had the cruise
set.  When the squaling happened, I could feel the
cruise blip briefly but then hold the speed.  However,
the needle would flutter reading about 10 mph higher
than I was actually driving.  As soon as the squealing
stopped the needle dropped right back to the actual
speed.

Unfortunately, the squealing is really
intermittant--it very well could go several days or
weeks again so I can't test by just unplugging the
cable from the speedometer.

However, because the cruise held the car's speed
correcly even though the needle read high, I think it
is probably an issue in the speedometer itself.  The
cruise control takes the speed reading off the back of
the speedometer.

Is there something in there that could be lubed? 
Something loose that could be tightened?  (I'm
thinking something kind of like the odometer gear that
needs to be superglued sometimes when it comes loose.)

Thoughts?
