The necessity of a cat has been the subject of quite a bit of discussion on several threads on here. I have no cat on a 2006 model TD5 and no one has told me I need one to pass the MOT - it's not been a problem the past couple of times. I'd be interested in hearing from anyone who's specifically been told by their MOT garage they had to fit one in order to pass. I still have my old front pipe with cat so could put it back on if need be, I've just not been asked to. Yes, better running without the EGR, and a lot less soot getting recirculated down the inlet manifold.
Did post a quote from MOT rules/law book all changed 2014 Feb. said cat/dpf missing will fail if it was factory issue. May be inspector is turning a blind eye.

My 90 300tdi 1995 had its mot today . I recently fitted a new
Stainless system without the cat on the front pipe . Only comment from tester
Was... did it have a cat before the new exhaust to which I replied.. no idea came as is when I bought it.. so would imply there is no way of telling if it had a cat fitted on such an age of vehicle.. I'm guessing it must be at a certain date cars HAD to be fitted with a cat.. and up till then was just if it was fitted but no way of verifying if it defiantly had one.. any way I'm happy it passed

Quick Question I have a 90 Td5 54 plate and am looking into straight piping it, is it legal to remove the cat?

No. And I am fairly sure it will fail MOT under the new rules.

Mine passes with no cat!
Mine didn't. What age is yours?

2009 fender 2.4. They never even mentioned it!
Lucky. They didn't do their job properly.
Mines a 1996, so borderline in terms of CAT fitted. Some were and some weren't around then. I considered not putting the CAT back after the rebuild. Problem I had was the MOT guy had MOT'd it for the previous 9 years with a CAT on and he knew about the new regs. He might have let me get away with it, but I knew he knew it used to have one and I didn't want to put him in an awkward position.

Aye but I may have the bigger issue this year - October ! We will see
What, the EGR?

That has also been removed prior to mot and no mention either. The fender is undergoing a head gasket rep so hope no issues when I re assemble
Good luck with the head gasket, do you know why it developed an issue?
Mine is also without EGR, so it'll be interesting what the MOT guy says when mine's due.

I thing the gasket may have failed due to no four injectornover fueling / the injectors have all been replaced now and I had them all programmed so hopefully is should be ok. At the same time I am replacing the timing chain as it's done 120k, the water pump, the oil cooler - asthis as has the original on and on a transit ( same engine ) they fail! Along with a set of valves and valve seats, silicone hose kit and expansion tank. I will be glad to get it completed
