right, for a start, the're not catalytic converters on diesels. they are particulate filters!
and id be very surprised if it will pass an mot test with one "knocked out" or removed.
plus the mot regs are changing as per the smoke dencity next year i think. down to 1.50m-1 mean over 6 accelarations. for all diesels 2004 onwards. alot of diesels are guna fail this!
im a tester and ive read it in a special notice a couple of months ago.
Right, for a start.........(Nice way to start a reply to a friendly thread 'murran'???)
1) We all know that only petrol engined cars have 'catalytic converters', but we also recognise that this is the diesel equivalent.
2) I have had my last 3 diesel cars all 'de-catted' and they do indeed pass the mot. My other VAG diesel, which has also been 'de-catted' by the way, passed this year with a test result of 0.29 1/m (Fast Pass).
3) This years mot had a Fast Pass test limit of 1.50 1/m, so under stricter tolerances you mentioned it'll still be well within the parameters.
4) If you say these stricter pass limits are to be applied to 2004 onwards vehicles, then that's fine with mine and the OP's being 2003 models.
5) Density is correctly spelled with an 'S' and not a 'C'
.
To be totally level with you murran, if by de-catting it meant that I'd need to refit a cat every year for an mot I wouldn't have it removed in the first instance. But to come on here and basically preach that we're all sinners for doing such a horrid thing and that we're all gonna come unstuck is just a bit rich for my liking.
We don't all remove the cat just to try and make the turbo spool a bit quicker and squeeze another ounce of performance from the engine. I know someone who was faced with a rather large bill for a replacement cat because the flange at his downpipe was split, so he decided to delete the cat to save on the unexpected expense, and there's nothing the law or mot testers can do or say about that is there?

There, rant over, but the manner in which you responded warranted my long-winded reply.
