Guest proudscotia Posted September 2, 2009 Posted September 2, 2009 Here we go again!! MOT time again and car(2004 2.0 Hdi 110) booked in to supplying dealer.Got call to say that car had failed on emissions.Having had dealings with this shady bunch before,I took it my local garage for a 2nd opinion.Failed again on emissions(mechanic told me car was belching so much blue smoke he thought engine was on it,s last legs) Having had issues with this problem before(see previous posts)I took car back(after giving it a good blast) the following morning for retest at which point it passed with a fast pass. The tester couldn,t believe it was the same car!!He had a look at the engine giving it a few revs and said that it seemed to be making a "whooshing" sound while being revved. I seem to recall reading a post on here about these types of symptoms having something to do with a split pipe at the turbo but Sods Law being the order of the day I cant find it!! Having a limited mechanical knowledge,I,m at a total loss so if any of the good souls who frequent the site can help me out I would be eternally grateful. PS Have just noticed that this post is duplicated so I apologise for rattling on!!!! Quote
coastline taxis Posted September 3, 2009 Posted September 3, 2009 is there any loss of power when its given smoke out. also have you got the print out for the emissions Quote
myglaren Posted September 4, 2009 Posted September 4, 2009 A bit of a WAG without further information but oil in the intercooler from the turbo bearings. The run will have cleared most of it out. Nothing quite like an Italian Tune-up. Take the intercooler out and check for oil (there will be a small amount, which is normal) and check the hoses for damage. Quote
Guest proudscotia Posted September 4, 2009 Posted September 4, 2009 is there any loss of power when its given smoke out. also have you got the print out for the emissions No there doesn,t seem to be any loss of power when it,s giving smoke out,the print out for emmissions was - 5.1-4.78-4.23-5.04-4.89. When I took it back for retest the emissions reading was 0.89 Quote
coastline taxis Posted September 9, 2009 Posted September 9, 2009 had you put anything in the tank prior to the mot to help the emmissions ?. Quote
Guest proudscotia Posted September 16, 2009 Posted September 16, 2009 had you put anything in the tank prior to the mot to help the emmissions ?.No nothing at all and it was running on Shell diesel. Quote
techbod Posted September 16, 2009 Posted September 16, 2009 service required oil/oil filter/air filter/some stuff in the tank to clean the fuel system that should do it. Quote
Guest digitalinkjetman Posted September 16, 2009 Posted September 16, 2009 Had mine MOT'ed last week, they took the probe out and tried it on another car because it wasnt detecting anything from my exhaust!! Super clean!! Quote
