	Had the 924 in for her MOT this morning...apart from a loose connector causing a headlight fail (sorted there and then) all is pretty good apart from a couple of advisories which I posted in chat by mistake. Anyway my question here is regarding emissions check... Came back as CO 1.02 against a 4.5 limit and HC 383 against a 1200 limit. Last year it was CO 1.140 and HC 268. just wondering why the HC level has risen so much and what maybe a cause? Although very happy with the results again

	Could be any number of things from todays weather conditions to quality of the oil in the engine or even the calibration of the emissions analyser. Even the state of the air filter can have a marked effect. An oil and filter change along with a good hard thrash just before the MoT can work wonders for emission levels I wouldn't worry about it, variations year on year are normal.
