Sorry but I don’t think that you do....
EGR blanking on the earlier 2.0d doesn’t usually cause problems and an MOT tester will probably never spot it but the CAT removal is obvious to all - including the police and DVSA though they aren’t likely to pull over many S40’s unless the exterior is also modified.
My point is that you bought a modified car, and those modifications are not ones that would have been done by a reputable garage or tuning company, so I would question whether they were done well and what else has been done to the car in the mistaken belief that it will improve it? We have had new members on here before that bought de-cat’d cars and it soon became obvious that it was really done because the old cat became clogged due to injector/overfuelling issues, often arising from bodged upgrades and tuning boxes.
My advice would be it is pointless and expensive (as you have found) trying to sort the car as it is - your best option is return it to standard spec (shouldn’t be too expensive, use second hand parts). Once it is running well and as it should do, then make any modifications you want to, one by one and assess the impact of each. If it has a tuning box - get rid of that too as they are usually hopeless.
The issues that you describe do sound fuelling / air leak related though.
So I’m sorry if I’ve not been nice to you.... but not giving you a honest opinion isn’t being nice either....
Good luck.
