No speedo working on two different clusters

[UrS4boy]

Looks like you DID get really bored later that day..
Great job

Actually it was obsession.

Wasn't that bad in the end. Put the whole post in WORD and substituted the new pic url (copy paste) for the old pic url. Probably only took 10 minutes.

This is from Audiworld. Unfortunately the idiots who run that waste of time decided to arbitrarily change the urls for the photos in the picture posters (what idiots), killing many many good posts (including lots of mine). Hate them.

That said I found this thread. You want to go to POST No. 1

The photos are in the poster's (qcrazy's) album starting here:

Just open up the thread in one window and then open the photos in another and switch back and forth between text and scrolling to the appropriate photo.

IF I get real bored later today, I might edit the poster's post with the proper links to the 13 photos. MAYBE.

Good luck

I'm still willing to swap out the vss as there so cheap,

Am I right in thinking that the difflock wouldn't disengage if the vss was broken, or that the odometer wouldn't work?
And how much is a new cluster these days?

Based on the evidence, your G22 VSS sender is fine and portions of the G21 Speedometer are also fine. It would appear that the issue is the actual speedometer not the odometer or the output from the speedometer. You don't need a whole cluster, even *IF* they were available new. Try to find a good used speedometer.

Just to confuse things, the difflock is disengaging as it should, plus the trip counter is working , I'm confused now as both those get there signal from the vss, or am I wrong ?

Well it must be the speedometer then. 2 in a row is unlikely, but it must be it.

What happens to the VSS after the G21 speedometer

From my G22 info link that I provided previously, here is what happens to the white/blue wire output from the G21 Speedometer on a UrS4/S6 (S2 list will be similar, pins and connectors will be different):

yes i know, but unfortunately i decided to go with the ring first, and the with the sensor

[UrS4boy]

Well I had it changed in mine (the problem was in vss anyway ) but the problem was too intermittent to be easily identified. You do not need to remove the box. Just remove DS axle, drain the oil and remove the side cover with CV flange. Not a common problem, but i know it has happened before.

So you could have save the time and money and NOT gone to the effort of replacing the 012409187C sender ring by just replacing the G22 012409191D sender. That said, it is good to know that the transmission doesn't have to come out to see and replace the sender ring, as shown below. I will add this info and your comments to my G22 info post.

Sender ring:

By buying and installing the VSS sender to see if that it the issue first. The sender ring, item 8 below, well inside the left drive flange and would be a major transmission out of the car replacement task and besides, when is the last time you heard of one failing (NEVER).

How did you rule out the sender ring?
