DPF/EGR/Turbo issue?

Hi guys. I have kind of a complicated problem, hope my English will be good enough to describe it.
I drive e220 cdi 2013(facelift) coupé, and I am starting to go crazy about this
It started maybe a year ago with DPF regeneration process starting really often. I thought it is just because I drove mostly short distances lately, so I brought it to highway, to do some oldschool DPF cleanup.
I drove like 20-30 minutes on 3200RPM. So high because I do not have manual mode. I do have paddles, so I can shift manually, but after 15 seconds it goes back to automatic mode. So I found a way - 112km/h speed at 3200RPM, hitting - paddle every 10ish seconds to keep the gearbox from shifting.
It seemed OK for a while, but then I got the problems back. Diagnosis showed codes P2279, 2281 and P0299.
The DPF regeneration was back again, combined with limp mode.
After some time spent under the hood I noticed damaged hose. The big one on the bottom of the enigine room. I think it is the one that takes cooled air to engine.
So I changed it, cleaned the DPF again (this time I even used some additive) and it again seemed OK for a short while.

Then again, the same story. DPF clean mode rly often and limp mode. I found out that the other one big *** hose is damaged, this time the orange one.
I have got a photo of this one. I took photo of the number, bought it, changed it, cleaned DPF again.

Damaged hose #2

Then I went to my friend for diagnostics. We found these problems





After clearing those messages, my car drove OK for 5 days. 5 days without DPF cleaning process, and then, on the 6th day, i got limp mode like one minute after I drove off.
No yellow engine light, just limp mode, with transmission working rly funny, power limited.
After I restarted my car, it drove normally, but the DPF regeneration process is back, so I expect my car to go to full limp mode shortly.

Do you have any clues, what could cause all this?
After finding those damaged hoses, I thought that they could have caused increased production of smoke, polluting the DPF really fast.
But after that last fail, I am not sure, if I should clean my EGR(that could cause my DPF to pollute rly fast too, am I right?)
Or is it a problem with my turbo?

Again, sorry for my English, I hope you will be able to understand my issue. Do not hesitate to ask, and thank you for your time

Boost pipe

Boost pipes and intake manifold or "throtele body" and intake manifold. Chek those first...

Yea, it was a combination of one busted pipe, and two faulty lambda sensors.
