Saxo 1.1 TU Failed MOT on emissions - Dave - 23-08-2013 I have a saxo 1.1 which has failed on a bunch of mechanical stuff which is no issue to sort, my main concern is it failed on the C0 part of emissions. Pass is 0.3 I beleive, and this has scored 0.55 - apparently this is just over the pass rate? Anyway, I honestly havent a clue about making petrols run better, im mostly diesel, so my question is, how can I fix this? Slacken off cable so it cant rev as hard? stop the TB opening as much? this is how I do my derv :p Change the lambda sensor? do these engines have maf sensors? It has a stock air intake, but the exhaust has a gutted diesel backbox on it, so its slightly free-er flowing. I didnt really want to have to put another backbox on this as its welded straight to the exhaust and would require cutting off, but if this is the source of my problem then I shall have to. Just wanted some ideas cos I havent got a clue Saxo 1.1 TU Failed MOT on emissions - Jonny b - 23-08-2013 I would guess at lambda bud!! Though that result could have gone through after a good ragging Saxo 1.1 TU Failed MOT on emissions - Frosty - 23-08-2013 Prob be the cat but I would recommend doing the lambda sensor at the same time RE: Saxo 1.1 TU Failed MOT on emissions - daddyfixit - 23-08-2013 cats for these cost buttons by the way, same as 106 xn--about £40 , but the lambda sensor was expensive (ngk) at about £60............I had a 1.1 tu 106 fail 2 years in a row, tried cataclean the first year and it passed but this year it didn't work, put a cat on it and passed.

RE: Saxo 1.1 TU Failed MOT on emissions - Rippthrough - 23-08-2013 What was the lambda reading? RE: Saxo 1.1 TU Failed MOT on emissions - darrenjlobb - 23-08-2013 Give it total abuse on the way there, will probs pass then, failing that most likely lambda / f*cked cat due to bad lambda, seems to be only thing petrols fail gas test on Saxo 1.1 TU Failed MOT on emissions - Sambarker - 23-08-2013 "Was a bit high on emissions, so just stuck another car on instead" RE: Saxo 1.1 TU Failed MOT on emissions - samass - 23-08-2013 What arrange said, maybe a bit of redex, I've done that in the past and that's made them pass. Getting it f*cking hot before the test helps a ton too RE: Saxo 1.1 TU Failed MOT on emissions - HDIkyle - 30-11-2013 Burn it. Best thing for a tu engine, and a saxo. I know I have one RE: Saxo 1.1 TU Failed MOT on emissions - Dave - 08-12-2013 Ok just to update the outcome of this, I put some Redex in and got it real got before the test and still failed on a similar reading. The bloke was cool and apparently hit the wrong button though so can't complain. I sold it two days later for ££275 and a years mot on it.
