Finally got round to fitting the Allard EGR delete pipe. As the intake manifold was also dirty, I decided to do the right thing and remove it for cleaning as well.

The EGR was filthy, and this with only about 20K (tuned) miles on the car - about 35% blockage. I has some issues with hesitation with startup that have gone away now (likely sticking EGR flap).
The manifold had about 3-4 mm of gooey sticky black crud that scraped off like dark cholocate icing. The actual intake ports had a full 2mm of the stuff choking the exits.

A whole can of carb cleaner was used then to clean it, and air blown through to make sure there was no residual cleaner left in the manifold. This has to be the dirtiest bit of DIY possible! Took me 3 days of scrubbing to clean my hands with you name it....

Results:

Excellent tbh - the car starts better, revs faster, less smoke, more power felt and power is smooth all the way to redline. I let the CEL issue put me off this mod for a long while - too bad.. Don't notice any shutdown shudder, even though I was expecting some...

Well worth the trouble and the considerable mess!

Is this a hard job to do?

I used to do a little bit of work on my mini but havent touched the fabia.

Can u balls it right up if you dont no what your doing?

Its obviously worth doing, my car is coming up to 3 years old and has 29,000 miles on it, would it be worth paying a mechanic to do the work?

how many hours of labour do you think they would charge me?

If you just want it cleaned, perhaps 2 hours. Easy enough to whip the EGR/mainfold assembly off the car. But if you want to clean the actual manifold that means unbolting the manifold off the head, which is tricky due to lack of space. The cleaning itself will take most time I reckon.

Not that hard to do, tbh. Took me about 3-4 hours:
unclip rubber air hoses either side of intake manifold.
Unbolt EGR from manifold and turbo.
3x 5mm head allen bolts to intake, 2x 10mm (or was it 12mm?) bolts to turbo.
If you're fitting a EGR delete pipe - fit the blanking plate now - you dont want to drop anything inside the turbo! otherwise cover with a plastic bag/elastic band.
Remove 2 tight rubber vac hoses from EGR
unbolt 2x 10mm bolts from top and Left of intake manifold.
unbolt intake manifold 6x 6mm allen key head bolts - you'll need to feel for them and/or use a mirror.
Pull off manifold and remove metal gasket.

on re-assembly - use a new metal gasket (preffered). Need to judge (guess) 18 Nm of torque - just tight and then a bit....The intake bolts need a combo of different length 6mm allen keys - some ball-headed ones would've helped, but I didnt have any...

Really FILTHY job - anything you wear will become garbage....
If you plan it as an overnight job - soak the manifold in some solvent in an enclosed container.
Things to watch out for - dropping stuff into the turbo/EGR union (very bad). That's why if you have a blanking plate - fit it first...
But it really is worth it....
