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!
