    The number of vehicles failing the emissions test has significantly increased following the introduction of new stricter limits in May of this year.

    Since the DVSA changed the MOT test six months ago, official figures show that nearly 750,000 cars have failed the new emissions test.

    This compares to 350,000 failing during the same period in 2017.

    A total of 238,871 diesel and 505,721 petrol cars failed the new emissions test and cannot pass the MOT until they have been repaired.

    The new test also saw a 548 per cent increase in the number of diesel vans failing emission tests, increasing from 3,585 in 2017 to 19,648 in 2018.

    There would have been more failures if the garages had
    8updated their machines at the correct time and use the parameters for testing Emissions

    BG EPR will reduce emissions on all Petrol and
    Diesel vehicles when used as a mandatory service
    Item because it restores compressions and by
    Cleaning the rings it eliminates oil blow-by.
    This reduces deposits in the manifold,EGR and DPF.
    It also lowers exhaust emissions.
    The inclusion of this product as a routine service
    Item will reduce this number of failures

    Diesel figures not a true indicator. Still to many still testing on old limits, we recently failed a few on new limits when on investigation dpf was empty, next day an mot issued elsewhere. Still going on and out of order.

    So what is happening about “illegible” diesel plate limit stickers? These limits need to be put onto the MOT system as brake test weights are because word is getting around that if you scratch the sticker off the car gets tested to default limits!

    The DVSA did have a fail for the sticker being illegible but then I noticed later that the rules had been relaxed and now when that occurs we test to default. I must admit though as a full time tester my fail rate of diesels is 24% of a recent 138 diesels tested, which equates to about 33 vehicles. The national average today shows 11.8% for the whole country, and that means 88% of diesels are passing their test, whether default or otherwise, the statistics don’t show those figures. Maybe things are not quite as bad as being made out to be?
