Just got a fail on emissions for the first time in 6 years of owning her :>(
HC's were OK at 34ppm (max=200) but the CO was .41% (max .30%)
Other salient point is she has been spewing a lot of smoke (and filled the MoT bay with blue/brown smoke on the first run up) but that was not mentioned on the sheet, and it was almost clear on the second run.
I need some experienced thoughts please-
I suspect that the oil smoke is not affecting the result as it would register as high HC 's??
On the CO front I recently fitted a set of refurbed and cleaned white injectors - could this be the reason for a high CO reading??
Before I start willy nilly attacking different bits - can anyone advise where the best place to start might be?
I havent done the PCV (yet)
I do have a new turbo and will need to do the vale seals but not planning to do now if it doesnt affect the CO reading. Thats the main target.
She had a 10k service two months ago (before injector change)
The lambda light does come on periodically so its clearly trying to self adjust.
Cheers
