Presumably the dual mass flywheel / clutch / transmission is at the owners risk.

There's a story doing the rounds that VOSA intends to make 'illegal engine ecu modification' an MOT failure in the near future.
VOSA admitted that the MOT tester has no practical way of checking if the original ECU has been remapped, so it's down to the tester spotting any piggyback unit hanging off the wiring harness.
Of course what that means for the dozens of companies selling ECU remaps or how you'd insure a car that would be an MOT failure is still an unanswered question.
