Think the early D3s were Euro-3 too. EU4 was only from the 2008 model year on?

Yeah, I think I would go on this assumption too, as removing EGR is not really much of a different matter regardless of being Euro 4, 5 or 6.

Thanks all for the replies so far.
I think I'll put my pipes back on, but put blanking plates on the lower end of each pipe, i.e. still blanked but much harder to spot.

If a tester does notice, what would happen? Is it reportable to the DVLA?
It's logged on the DVLA database & if you take the vehicle to another testing staion it will flag up.

Must confess I’ve had mine blanked for around 5 x years and the throttle body , map sensor have remained remarkably clean
Since I done mine I’ve felt that the engine runs smoother , but more than likely it was down to the intercooler hoses leaking

Hi
always a team effort and such awesome members here that will always help , god knows I’ve had some fantastic help along the way in with saving a fortune in not relying on garages
that’s what I done in fitting the blanking plates down by the engine block end , used a small amount of black RTV sealant on both ends of the EGR pipe ends , particularly after finding the air leaks
Ref the blanking plates I found the bolt slotted ones easier to fit as can just loosen the egr pipe end and slide them in , after I tightened the pipes up I put another smear of RTV round the sides of the blanks as then with it being black totally hides them
Also not wishing to try and teach u how to suck eggs but plse ensure u remove the butterfly valve plate , then refitting the butterfly pin
Plse let us know how u get on

Already done that part. The guide said it was one of the most difficult/brittle bits but I found it very easy!
Hardest part was getting the bolts off for the lower section of the pipes. I'm hoping to avoid all of that again, hence this discussion

Forgot to add a picture of those slotted blanks
Hardest bit I found was refitting those EGR pipe clips , do u have the pliers plse as if not can show u a picture of other pliers that makes life easier

Those blocking clips look a hell of a lot better for getting the job done.
Not sure what pliers/clips you mean though. It was a while ago so can't remember what tools were needed. I remember I had to buy a universal joint socket and extension for getting down to those lower bolts.

If you buy a new throttle body it comes with the two funnel shaped pipes bolted to the side. The actual EGR pipes ends in a similar funnel and the two are joined by a V clamp closed by a pipe plier but with parrot beak jaws.A visitor from the dark side, my other vehicle is an is still an EV. Strictly speaking its SWMBO.

Glad u liked the blanking plates
Apologises , here’s the pliers I mean , knipex do some pliers but these type of pliers in the picture work fine
If I may plse add , I applied some plumbers silicone clear grease onto the large O rings on the throttle body, made life a lot easier , did replace all 3 x O rings as the old ones weren’t in very good shape
Found it easier to connect the egr pipes to the throttle body first before bolting it down
Hope that helps

Quick update on this and a new follow-up question.
Over the past couple of days I've reattached the pipes, but left the blocking plates on at the lower end where the exhaust gases come from.
Now, because I'm an impatient moron I definitely rushed it (the work was done during two separate lunch hours).
The result?
Passengers side pipe: Gasket fell irrecoverably into the engine bay somewhere so I reattached it without.
Drivers side pipe: One of the bolts holding the lower end of the pipe snapped! So I've reattached the pipe with only one bolt.
How screwed am I? How much pressure are those things holding back? I've started the car and it seems fine.
It presumably won't die just going to the MOT centre and back?

Well it passed!
Went with Kwik-Fit.
Also, interestingly/luckily, I didn't need to get my ECU updated to deal with the engine warning light coming on. I recently found that if you use a tool to clear error codes, the engine warning light doesn't come on straight away for the blanked EGRs, it takes a few drives. I chanced it for the MOT by clearing the warning light just before getting there, and was successful. When I turned the car on to drive away, the light came back on!
