Nct emmisions fail

Could also be the lambda sensors reading lean so the ecu is over-fuelling. Try unplugging them as a diagnostic step as the ECU will just run open-loop using the MAF. If it improves the reading then replace the sensors. If not, look elsewhere

Just following up here. Have replaced left bank o2 sensor as it seemed dead according to the diagnostic in the garage and after a smoke test 2 breather pipes from the inlet manifold were split open.
After that the emmisions in the garage recorded fine, so nct retest Tuesday... Fingers crossed.

Passed retest... Was the above. Whoop whoop!
