Hi,
Can anyone tell me where the speedometer cable located on the 2002 Jetta?
(posting a pic would be nice) The mechanic I went to said I needed to
replace it.

Not hard to find one if it has one. It runs from the Speedo to the left
front wheel or transmission. Some cars are using electronics so it could be
just a wire.

Do you know if you need an inner cable or both?

It could be a really difficult job due to poor access and because part
of the job may need to be done from under the car and the car needs to be on
a lift to get any kind of reasonable access.

If you are sure you really want to do it, get the part(s) you need from
VW and you will at least know what it looks like and what you are looking
for.

Hold on there a minute. A 2002 should be under warrantee, why are you
even considering doing the work. Let VW do it for free.

There is no cable. There is a gear that is driven off the diff, and on
top of the gear is a sensor that a wiring harness plugs into.

Now then, why were you told you need a new "speedometer cable"?

Thanks...

That's what I wanted to find out. I took my car to a mechanic (not a
dealer) to replace a driver side mirror. Apperantly the mirrors only fold
backwards and I broke one off when I backed off between two waist high
poles. I mentioned that my speed seems to be underestimated by speedometer.
I checked it against those automatic radar displays on the highway. He said
that it might be the speedometer cable that wears out or something to that
effect. I decided to ask and see for myself before committing to a repair.
And also, I don't want to deal with the dealership mechanics if I don't have
to..........they take too long and overcharge you. Thanks for the info
again. Now I just have to find that 'sensor on top of the gear' and see if
it's OK.....

By how much do you suspect it is underestimated? Are the tires of the
original size and make?
I would also consider a different mechanic... most modern vehicles utilize
electric/electronic speedometers.

I have had a number of speedo cables wear out and not one caused
inaccurate readings. I suggest a different mechanic.

Agreed. I don't know much about speedo cables but I'd imagine that it's all
or nothing (it either works or it doesn't and nothing in between).

I don't think a new VW *has* a speedo cable anyway. In any case, a
failing speedo cable usually causes a fluttering needle, not inaccurate
readings. Once it starts reading low that means the cable is "winding
up" in its housing and will fail in a matter of seconds.

Then tend to cause vibrating indicators and often get noisy. Then they
just break.

What makes you think those displays are accurate? There are two at a nearby
school. They differ by 10% when my car speedometer reads the same value.

Probably not...nor for the past 10 years or so. The A3s have a label on the
cluster that says "VDO Electronic" so that indicates that when the A3s
debuted that VW probably started getting away from cables.

First off, don't place much faith in those road side radars.

You can try doing 60MPH and see if it take you 1 minute to from mile
marker to mile marker.... but I put about as much faith in that as I do
road side radars.

If you really want to know for fact, then you need to take your car to a
pro who can slap the car onto one of those "road test" machines and see
if the speedo matches the wheel speed. We don't have these in my area
since (luckly) we don't have state inspections [ie-another wheel tax].

Does the speedometer needle ever "float" between readings. For example,
if you are driving say 70-ish and keeping a steady pace with traffic,
does the needle float back and forth between 60 and 70, or would it stay
steady right there at 70.

If the needle stays steady right at 70 for my given example, then your
sensor that is screwed into the top of the tranny is fine. I have seen
where the plastic gear that is pressed onto the diff cracks and then
slips, thus causing the floating needle. Only seen this on automatics.

I find that a good GPS unit can give a very accurate and very easy to
use measure of speed.
