In the Foxwell when you do the "clockwork" test it runs all gauges and clusters and can leave one stuck (did on mine) but usually fixes itself. On the off chance maybe disconnect your battery and put the + and - together for 20 minutes and re-run clockwork test and maybe everything will be cleared.

For all other ideas dm Andrew because he's definitely the guru you need.
