Steering column gaiter split

[NiceCupOfTea]

Noticed that the gaiter on one of the steering column knuckles (the one you can see easily through the wheelarch) has a split. According to Steve Heath these didn't have gaiters from the factory, but does anybody know if this will fail the MOT. Don't want to pull it off as obviously a split gaiter is better than no gaiter. Was going to replace with one of this split self adhesive ones but I can only find them for driveshafts with one end open.

Doesn't seem to hard a job but I don't really have time to take the column apart at the moment...

So....

Tear it off? Anything I should lube it with? Just cover it in lithium grease?

MOT tomorrow and of course I have done nothing about this. If it's definitely non standard shall I take it off? Will it fail with a torn boot even though it doesn't need one?
