EGR blank vs MOT (UK)
TL:DR;
1. Can't be arsed re-fitting EGR pipes just for MOT. Big risk?
2. Anyone in North Yorkshire know any MOT centres that have passed their EGR blanked disco recently?
UPDATE:
- I refitted the pipes but left the blanking plates on at the lower end
- I managed to completely bodge it and will need a difficult repair later (lost a gasket on one side, and snapped a screw holding the pipe on the other!)
- MOT passed - at Kwik Fit
- Found that if you clear fault codes before going in, it gives the car enough time to pass the MOT without the engine management light coming back on again. (This is for a 2007 model which is just about new enough to need an ECU update after EGR blank)
______
Apologies in advance, I feel this is an old and widely discussed topic but can't find anything recent enough and pertaining to exactly what I want to know.
Upon advice from a lot of people on facebook a few months ago, I resolved a dodgy EGR valve by performing a full delete and removing the pipes.
I have since learned that this could result in an MOT fail, as it's tampering with an emissions device. If you know what you're looking for, it's pretty easy to peer into the engine bay and see the pipes are missing.
However, from what I can I see on forums like this, EGR blank is a thing done by a very large amount of Disco owners.
So what is the current situation regarding MOTs? What are peoples recent experiences?
Worst comes to worst I'll have to put the pipes back in, but would rather not waste the effort of doing so if the chance of it being spotted is slim.
Thinking I'll just do it at KwikFit, or the local garage who turned down a wheel bearing job on my car because "we don't do big vehicles", as they presumably don't know a great deal about Discos so would not easily recognise missing EGR pipes if they even looked that close.
Or does anyone in North Yorkshire know any test centres that have passed their EGR-blanked disco recently?
Or should I just suck it up and refit the pipes?
Thanks.

As long as the plastic engine cover is on, most ppl aren’t going to spot it.

Yeah I've seen a few comments saying that. I was just a bit surprised because I can spot it easily even with the engine cover on - now that I know what to look for.
I guess another question would be: If a tester does notice, what would happen? Is it reportable to the DVLA? Or just tell you to fix it and come back?
I suppose I could feign ignorance and say I bought it like that.

Yeah. Best to worry about it if it fails.

You get 10 days to fix and return for MOT, if not fine issued and vehicle taken off the road.

Sorry to say but have known 2x D3 owners where the MOT tester spotted the missing pipes
Plus 1 ^^^ with regards to allowed time to correct ,
In the past, car owners attempted to remove EGR valves and Diesel Particulate Filters (DPFs) from their vehicles to avoid costly repairs.
However, for Euro 6 Emissions Standards compliant vehicles it has now been stated by the Department for Transportation that removing the EGR valve or DPF is illegal as the vehicle will no longer be compliant with the road vehicle regulations.
Vehicles will also fail their MOT test due to emission levels emitted and owners can face an astounding £1,000 fine for removing the EGR valve or diesel particulate filter.

What fine? Sounds rubbish to me.
Plenty of cars fail mot's and take longer than ten days to get fixed.

From memory it was £200 for each EGR.
I'll find out more this week and to be fair he had an 'abrasive strop' with the tester.
Should gave kept his mouth shut!

It's not going to take 10 days to replace the pipes?

Mine's passed seven MOT tests with a blanked EGR. No-one's ever even mentioned it.

Not sure how it works regarding technicalities but D3 is Euro 4, not 6 - if that makes a difference?

As a side note and hopefully this helps but when I refitted my egr pipes I had a boost error, found the egr pipes were leaking after applying my smoke machine to the throttle body
The short turbo hose was also leaking , so replaced the 3 x intercooler hoses with silicone ones using T bolt clamps , short hose was the hardest to replace
Map sensor like many others was blocked , I got a genuine D4 map sensor as it had a larger orifice , was extremely pleased of how it drive afterwards , Map sensor / throttle body remained very clean after checking it a year later
Hope this may help anyone in the future

From what I’ve read and been told indeed will be illegal to blank or remove egrs / DPF’s on any model
Assume there stricter on the euro 6 models with them using adblue
Indeed as u rightly say ref the D3’s , think this is correct about the euro year data
Euro 2 January 1996 - January 2000,
Euro 3 January 2000 - January 2005,
Euro 4 January 2005 - September 2009,
Euro 5 September 2009 - September 2014,
Euro 6 September 2014
