Sensor reset, could be bank 3 being the culprit. Apparently a pig of a location to replace. We will see if reappears.
another flag was catalytic but inconclusive with further code information. 🤔 fingers crossed not the latter
The warning lamp has just come on - what are the omens with this issue? faulty sensor or something more serious. Will check if this reappears when I start the car up tomorrow.
