I put my Ford Focus (52 plate zetec engine) in for it’s MOT the other day and it has failed on all 3 carbon emission tests.

Min Max Result
Fast Idle test Fail
CO Level 0 0.30 0.75
HC Level 0 200 343ppm
Lambda 0.95 1.09 1.04

Min Max Result
Second Fast Idle Test Fail
CO Level 0 0.30 0.80
HC Level 0 200 229ppm
Lambda 0.95 1.09 1.06

Min Max Result
Natural Idle Test Fail
CO Level 0 .50 0.72

I’ve tried adding some K-Seal, also an additive to stop the smoke, and also injection cleaner.
The oil level is always dropping, but there are no visible leaks and also it doesn’t seem to be burning off as the smoke has no obvious color to it. Plus my EML is on.
The garage also done a compression test on the cylinders, and cylinder 3 is down by 100 PSI.
Can anyone shed any light to what the problem is, and how I can get it through an MOT the cheapest way possible?
