I'm pretty positive it's the right thermostat.
Based on the other issues you reported, it sound like your cluster may be crapping out. I also had the same thing happen on my sn95. Replacing them is easier said than done though. I bought mine new, which was pricey. Then you have to have the dealership set it and and calibrate it to your vehicle. If you dont get the mileage set up right....well its quite illegal. Try and swap out a gauge cluster from a salvage yard and see what happens. If that solves your issues have the dealership calibrate everything for you.
