Based on the info in the link you sent me (above), it now seems Atlanta Speedo can indeed repair my cluster.
Leading evidence: 'Repair cluster' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Repair cluster' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I saw Atlanta Speedometer in my earlier searches; their web site did not show any repair service for the later than 1999 Porsches.

If the answer to 2 is NO, then is the only solution replacing the entire gauge cluster?

That all makes it look as though it's possible to replace just the oil pressure gauge.

The backlighting on the Oil Pressure gauge of my 2002 996 C4 Cab works, but the red indicator needle does not light up, rendering the gauge unreadable at night (have to use a flashlight to read pressure).
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

The backlighting on the Oil Pressure gauge of my 2002 996 C4 Cab works, but the red indicator needle does not light up, rendering the gauge unreadable at night (have to use a flashlight to read pressure). I'd appreciate any information in the following areas:
1. Can just the red needle be replaced?
2. I the answer to 1 is NO, can just the oil pressure gauge be replaced?
3. If the answer to 2 is NO, then is the only solution replacing the entire gauge cluster? Or, are there other options?
Thanks.
I googled "porsche 996 gauge cluster lighting" and found several DIYs on replacing LEDs and so on. You might find some hints in those about what the problem might be, and how to correct it.
Good luck, and please let us know how it goes.
wdb,
Thank you for your suggestions. Unfortunately, my searches (prior to posting) had not produced anything near my specific situation. I'm hoping that the collective technical knowledge on this site will come to rescue. The problem, however, is not a "show-stopper"; just a nuisance.
Thank you for the link. I saw Atlanta Speedometer in my earlier searches; their web site did not show any repair service for the later than 1999 Porsches. Based on the info in the link you sent me (above), it now seems Atlanta Speedo can indeed repair my cluster. Will call them and arrange repair. Thank you very much.
BTW, I also contacted Palo Alto Speedometer, and they told me that their work is limited to analog Porsche gauges up to 1998, and that for the 996 and later models, they only do odometer resetting and certification.
I�ve got 2 spare clusters that I�m saving for parts. I�ll locate them tomorrow and see what�s what. From what I remember, the oil pressure gauge is clipped in but only tied into the main cluster board by a ribbon cable.
actually found some photos on my phone.
If the oil pressure gauge is as you've stated, that answers Question 2 in my OP. Once you verify that, then my search for the oil pressure module starts.
Anxiously awaiting hearing back from you.
Thanks,
Bahman
These definitely look like surface mount LEDs which would be lighting the rest of the gauge, and its not totally clear from the last pic but I'm guessing there's one more directly under the clear shaft and that's the culprit. If you're handy with a soldering iron it seems replaceable, but if its cheap to swap the whole part that seems easier.
e30rapidic, in Post #11, has provided excellent pictures which show exactly how the oil pressure module and needle are configured and attached to the cluster.
I am currently trying to source a complete oil pressure module, preferably new, and fix the cluster. If I cannot source a module, I will attempt component replacement. It may also be a loosened connector.
I appreciate all the help and suggestions so far and will update my progress.
@Bahman
I am facing the exact issues that you've described. Did you end up finding a solution? Thank you in advance!
@e30rapidic
thank you very much for the photos!
I was able to purchase a working Oil Pressure Gauge from e30rapidic and successfully replace mine.
During my research, I visited DC Auto in Rocky Mount, NC and purchased a used cluster with some modules missing, as a spare. It doesn�t have the oil pressure gauge. You may want to give them a call and see if they have another one laying around. Great people to work with.
The oil pressure gauge is common to all 996 clusters, and by buying a cheap non-operational cluster, you can harvest the oil gauge. Makes your search easier.
This is a source reference. Confirm exact model applicability in the original material.
