    Emissions FAIL clarifications

    Took to an alternative MOT tester who confirmed bad emissions They then run diagnostics which didnt pinpoint anything Instructed them to replace O2 sensor front, as advice earlier in this thread They went ahead clarifying they would not be liable for the replacement failing to resolve issue...

    Emissions FAIL clarifications

    Yes, thats what i thought. They have used diagnostic tools and found nothing, and there are no lights It does smell rich, and mpg not good- so as other contributors suggested have asked for the pre cat 02 sensor to be changed, then see where we are As said, the Cat (Supplied by Milltek) has...

    We'll see. Not spending lots on it. Mechanics did say pop in tomorrow to discuss solutions. Am too old to be crawling under cars. The other factor is the cost of Track days has escalated dramatically last couple years. An average one is £300+ all in, when it used to be less than £200.

    Took it to another place for diagnostics, and they're used to Clios, and it still failed even after Cat was "red hot". So, worst comes to worse, and it's change both sensors at least £100 each, then new milltek sportscat fitted for £650, then belts due Feb for £650, then possible new remap...

    Have bitten the bullet, and as i cant get to the connector of the lambda sensor on exhaust manifold from axle stands, have booked it in to get investigated. £45 for diagnostic and booked me in next day (Leave it there and they can have a look when they can) which i thought pretty good Lets see...

    Think i will take back to MOT tester, and have a chat and see if he can retest (After ive run through some CAT cleaner) and if test fails again ask him to replace the sensors, then if it still fails, may have to replace the Milltek Sportscat. I dont mind replacing the sportscat at £550 odd...

    Thanks for this. This diagram was shown to me in a parts retailer store. They were pretty confused which was applicable to where, as well. (And confuses matters a bit more when mine has after market milltek exhaust with a sportscat, but assume the sensors would be same anyway to marry up with...

    I have a reasonable scanner, but isnt as in depth as to check lambda sensor voltage

    No, they arent cheap. atm trying to find a video showing removal Believe there is one on the manifold (accessible engine bay?) and another on the CAT itself
