Engine using oil but has zero hydrocarbon emissions

[9xxNick]

I have a VAG 1.8TSi engined car which is using about a litre of oil every 1,000 miles, but has just passed an MOT with zero hydrocarbon emissions. I would have expected it to be on the high side (200ppm is the limit) when using this amount of oil.

There's no obvious leak, although that's an area I'll check again of course.

So, opinions - would this amount of oil burn show up on the MOT's hydrocarbon emissions test?

Yes, everything's as originally manufactured.
