Sounds exactly like our T8.330 issue. Ended up being a bad thermostat.
Edit to add: It has been 4 years since the issue happened, but if i remember right while the engine fault code would appear our engine temps were high. Was the only reason we found the thermostat as, like you, nothing appeared via diagnostics tests.
