Hi,
Quick update today - I popped outside to scan DTC codes using my generic reader.
It picked up P0808 - Clutch Position Sensor Circuit High - so it looks like it is the usual suspect.
I'm going to take it out and clean it and maybe even try the
cheap fix
Perhaps usefully for other owners - I have no check engine / engine system service required message and the cruise lamp works fine and does not go out if the clutch is raised.
Thanks
