I did a pod refresh, new bulbs, new foil..cleaned the connection ends all studs and nuts..everything..and I still have these two gauges that just don't work right.
Pod's gotta come out again, but what should I be looking at this time?? Nothing could possibly be cleaner...I wouldn't think...
If it wasn't like that before you worked on it, that probably eliminates the gauges and points to a connection issue.
Both of those gauges come through "plug A"...that would be where I would check, first.
Sometimes a reach behind and a wiggle on the connector will cure things.
Semi-retired, as of Feb 1, 2023.
The days of free technical advice are over.
Free consultations will no longer be available.
Will still be in the shop, isolated and exclusively working on project cars, developmental work and products, engines and transmissions.
Have fun with your 928's people!

These were why went in there in the first place...but remained funky.
I had a similar issue on my 951. Noticed that the gauge (temp/fuel) were only bouncy when I turned the lights on. Cleaned battery grounds and checked brown wires. Not sure which random ground cleaning cured it, but that was it.
Remove the stacked ground wires down by the pedals and clean them and the point where they attach.. Clean the main alternator ground. That oscillation in the needles is sometimes from the rotation of the alternator.
I'm not going to say that it isn't a good idea to clean all of the main grounding points, however I kinda doubt that removing the cluster and working on it is going to suddenly cause a connection issue at a remote bolt though grounding point.
.....Definitely not where I'm going to tell one of my guys to go, first.
Now if the problem existed before removal....that's a whole different story.
I'm not talking about all the ground points or even just the chassis ground points. This IS clearly a grounding issue from the symptoms - I'm not just guessing. Look at the chassis grounds specifically for the pod and also all the ground connections inside the cluster to the gauges. It must be a common point to all the gauges affected. As Greg says it is most likely something you touched - quite possibly internal to the cluster. On re-reading it seems you've had this a while - however its still a local issue to the pod grounds.

Well..like I said it was there BEFORE as well, nothing I touched started it. I was doing the foil and cleaning EVERYTHING (except that damn ground point back there) in the process.

Temp and Fuel Gauge all bouncy..
