Diesel drivers - you might be about to fail all your MOTs

20 February 2014

old car Do you have a diesel car? Have you had diesel particulate filter taken out of your vehicle?

Oh dear.

Seems, thanks to a crackdown, your motor will now face INSTANT FAILURE when you get your MOT done thanks to those kindly souls at the Department for Transport.

Modern diesel cars are fitted with a DPF thanks to European rules which said we all had to filter nasty nonsense and reduce emissions. It's good for the environment and good for your car tax.

Alas, these filters are expensive to maintain and they need replacing often. As such, some drivers have had the DPF removed. Now, if you don't have the filter in, like you're supposed to, MOT testing stations will have to fail your MOT. And then you'll have to get one installed. And maintain it. It's going to cost you a lot of money, basically.

Robert Goodwill, roads minister, said: "I am very concerned that vehicles are being modified in a way that is clearly detrimental to people’s health and undoes the hard work car manufacturers have taken to improve emissions standards. It has become apparent the government had to intervene to clarify the position on particulate filter removal given the unacceptable negative impact on air quality."

"This change to the MOT tests makes it clear – if you have this filter removed from your car it will fail the test."

Of course, the irritating thing is that DPFs don't work properly unless you're driving your car at a constant speed for around 20 minutes, as it needs to warm up. So even if you do have one and are only nipping to the shops and back, or in stop-start traffic a lot, it isn't really helping the environment at all.

Not that this matters. The Department for Transport want you to have one and they won't be budged.

    And just how are they going to tell Not seen any portable XRay equipment at the local MOT Station yet, its not like they cut the thing off, the DPF is hollowed out with all the gubbins removed and then put back on, Looks just like it did before. Will not fail the MOT as there is no visible evidence of removal unlike CAT Removals which are normally just replaced with a bit of flexipipe.

    "Alas, these filters are expensive to maintain and they need replacing often." Really? My 7 year old car has done over 80k miles and I've not had a hint of trouble from the DPF, so far it has cost me nothing in maintenance.

    And what if you're running your car on bio-deisel or WVO?

    Never changed the DPF on mine either, crap story hyped up!

    Why not simply sell us clean fuel that doesn't need filtering?

    bought 08 mazda6 2 years ago for £5500, approx. 2 months later dpf light came on and went into limp mode, took it to official mazda garage who quoted just over £5000 for a replacement, or advised I had it removed which I did for £300. Now runs perfect, no problems much better mpg and performance etc. How can it now be illegal when the official mazda garage recommended I had it removed??

    Damn right. Modifying your car to illegally pollute the environment, and the air people breath.. should fine the sods.
