Goosed Throttle Body?

Started up the Roomy the other morning after the long and spirited drive down to London for the Grafitti Tunnel Meet and had an EML with 'Exhaust Workshop' popping up on the maxidot.

Ran a scan today and it threw the following codes (not included full scan as all else was clear)
