New MOT rule regarding CAT

Tim4x4 · Feb 28, 2014

https://www.gov.uk/government/uploa...ata/file/275427/mot-special-notice-1-2014.pdf

So the new MOT regulations state that "any diesel originally fitted with a CAT will have to have one fitted in order to pass the new MOT test".

How do you check if one was originally fitted?

I have a copy of Land Rover's Microcat and by putting in my registration number it brings up the specification of the vehicle when built.

Under the heading Vehicle information sub heading catalyst description it states NO so leading me to believe no catalyst fitted as standard.

Under the heading Spec codes sub heading Exhaust gas recirculation it indicates EGR+CATALIST.DEFENDER [037AD].

Back to my question how do you check if one was originally fitted?

Anyone help?

Oh dear, that's a bummer if it applies to CAT's. Luckily I kept my CAT pipe when I did a decat.

Am I right in thinking you have a 2001 Td5? Early Td5's didn't have them as they were clean enough to meet the regulations at the time without them, when regulations changed, they were added. This was 2002 I believe. However, whether this is vehicles built in 2002 (in which case your fine), or, 2002 model year (in which case your's may be one even though built in 2001), I'm not sure. Whenever I've had a query regarding the build spec, I've found the parts dep't at Stratstone Stourbridge just up the road from you pretty helpful (helps if you're buying something though as well

).

What colour is your 110? I'll keep an eye open for you.

Im not 100 percent but I think for diesels its the DPF they are interested in, but if you cut the dpf open and gut it, then reweld whos ever going to know?

The link given by the OP states that it applies to CATS also. Could be a minefield this, don't know how easy it would be to gut the contents from a CAT or DPF and reweld unobtrusively.

That's the way I read it too, also includes CAT's.

There's a big discussion here:Defender2 - View topic - Decat and MOT...

Conclusion is that if your vehicle left the factory with a CAT, it will now fail the MOT if it has been removed. This must apply to a lot of members on here.

Thank you for the information most helpful.
It is Epsom green registered in 2001 comes up on records as a 2001MY but date stamps on fitted components in the vehicle are all 2000. I believe it was built in September/October 2000 and registered in 2001.

When I purchased the vehicle everything was standard I must admit I will be surprised if it did have a CAT fitted as standard. I have many but cannot be certain if all, service records and receipts for any work completed and NO record of a replaced exhaust pipe. The middle box and the tail box have Land Rover stamps.

I would say you're ok without then Tim, but if you pop in to Stratstones, they should be able to tell you if it had one when it left the factory or not.

FYI I popped into my local MOT station and (to do a belt and brace's job) my local main dealer as well.

In both cases I asked the question do I require a CAT to be fitted and working on my 2001 registered Defender TD5 for it to (a) comply with any laws and (b) to enable it to pass an MOT.

In both cases they said NO CAT not fitted to your vehicle from new so you do not require one now.

I also obtained the build date for my vehicle 01/11/2000.

Hope this will help anyone

That's just wrong, surely it should be more important what is coming out of the exhaust.

Mine is Decatted and at the Last MOT the guy commented how low the emmisions were. I had just given it a full service and cambelt change, so was planning to give it a full service (Minus the cambelt) the day before each MOT in future.

I've kept the cats from both my 110 and Dad's Disco (both are '03)

Our DOE (our nct for commercial vehicles or same as the mot in the UK) is a little less strict though. For our NCT, you need a cat alright in most cases however I think it jus goes on your emissions. If it can pass without the cat, then there's no issues with it.

Our doe just goes ok a smoke test so no real emissions tests yet but if its coming in for the UK, I doubt it's too far behind here.

I might put the cat back in for the test every year but not a hope I'll be fitting the EGR back in as it would mean I'd have to swap in a standard exhaust manifold each time too (that would probably warp again on the way to the test

)

I agree that what they have implemented is wrong and it is what comes out of the exhaust is important.
Let’s say that someone (a boffin or me) develops a piece of kit to be used on a diesel vehicle which is low cost and able to clean the emissions 100% (I know but stay with me) unless it was fitted to the vehicle at manufacture you would not be able to use it, having to keep your less efficient CAT.
In your case you have a vehicle when tested meets/more than meets the required levels may not pass an MOT without a CAT fitted if one was fitted as standard.
A discussion with my local MOT tester he said that a number of things (additional procedures to be incorporated into the MOT test) are introduced in the same way as this one but are removed again from the test. In some instances with no explanation why.

Google DPF delete, loads of places will gut your dpf and reweld so no one can tell its been doctored.
