You must not have a cluster out of a C2. I have put two different C2 Carrera clusters in mine and in both cases the fuel gauge is spot on. If it had only worked correctly with the first cluster, I might have considered myself lucky, but when both worked correctly, I have to assume that it's because I used the correct cluster.
One difference I did find is that the first cluster I used was from an '03 and the oil level could be checked with the engine running, while the second cluster (from an '02) requires that the engine be turned off, but the key on.
First Cluster
Second Cluster

I matched the part # on mine up with a C2 at the dealer before I installed mine, and yes, I still have inaccuracies- the cluster always reading "optimistic." I'd love to find a solution to this, Tholyoak and I have talked about trying a re-calibration, and if we do that I will report the results.

Tholyoak and I re-flased my cluster yesterday to a C2 Cab (there's no way to tell what it was setup as before) so we'll see if that cures my fuel inaccuracies!

Keep us posted. I was supposed to do the same last week, but stuff came out and I had to postpone. Later this week I hope...

Things are looking better. I recently refueled, we re-coded the cluster yesterday, and today while showing 3/4 tank I filled up and the car took 3.5 gallons.
I'll post more once I am able to run through a tank of fuel.

OK, I have now run a full tank of fuel through the car, and things are now fixed. Yay!
Turns out (well, best educated guess as you can't confirm) is that my previous cluster was from a C4 Cabrio. This completely explains my "optimistic" fuel gauge readings.
To fix this, and/or to code your 996 cluster to recognize the top in motion light:
Using the PST2, log into the car. You will need DME and Immobilizer codes to do this. You must tell the car it is a 996, as otherwise it will not recognize the cluster. Then, code the cluster to be a 996 C2 Cab. You must then tell the car that it is a 986 again, and load the appropriate map into the DME.
Tholyoak can probably elaborate more on this than I can as he is the PST2 master. Thanks for the help!

Thanks, I will do this later this week or next.
