Re: 146 Failed emissions !!! Help
Mine failed really bad on emissions, one problem was because the lamda sensor was totally fudged!
Even when it was replaced it failed again, so the garage I took it to put 2 bottles of injector cleaner in it and it passed with flying colours!!
If everything mechanical is sound, try putting the best injector cleaner in it you can find, I think the mechanic said it was £10 a bottle and he put x2 bottles in.
Also, before you drive it to the the test garage, take the car out for an "itallian tune up", in other words drive it hard for a couple of miles (taking it right up through the revvs (6500k mark), that should clean out any junk in the engine and works a treat, works just the same for diesels aswel.
Mot testing places usually give you a free re-test if you go back within a certain period of time, is this the same for you?
