Moaning Mot Failed Emissions

My car failed its MOT yesterday on emissions,
apparently the pass rate 0.9 of whatever and mine was near 9.
its burning a fair bit of oil. I have used an engine oil additive and he is going to test my emissions again for me in two days to see if it has made a difference.

Any other ideas on how to get my emissions down, new MAF and Air Filter fitted recently due to a water in the engine problem during the floods.

Re: Mot Failed Emissions

"Italian tune up" before you test the emissions. Rag the **** out of it, so your cat converter gets as hot as it can. Exhaust should be pinging when you park it up and switch off. Cat's work better the hotter they get.

Re: Mot Failed Emissions

It probably just needs a new lambda sensor. I had a problem with emissions on my last 145 QV so I bought a generic 4 wire sensor from ebay, wired it in and it passed with flying colours.
