Nissan Qashqai 1,6 dci C1132, U1000 errors

[CyGaN]

Hi. I have a big problem with my wife's car. Nissan Qashqai 1.6 dci 2013.
I've been fighting with it for three years (of course, in between customer cars... too rarely according to my wife, of course).
Four years ago, the DPF was clogged, mechanically removed, plus the program. Problems since then.
Moments after the DPF, the turbo and the head failed. Turbine regenerated, head replaced.
After all these repairs and almost a year of fighting, the car had trouble accelerating.
In first gear everything is fine, when stationary it revs normally. The problem begins to occur at a speed of about 60 km/h and revs above 2500. It loses power abruptly, as if something blocked it for two seconds and released it for another two, and so on all the time. There are no errors in the engine. Errors in ABS C1132 - Engine signal 3, U1000 - CAN communication fault.
Replaced abs pump, replaced pressure sensor and blown pipe to the sensor.
Replaced positive terminal, cleaned contacts.
It doesn't do anything.
The car does not want to accelerate smoothly, the ABS and ESP lights are on, and the AIRBAG light is blinking.
Does anyone have any ideas?

Your problem in ECU, Nissan ECU is the last thing you want to tamper with removing DPF or Addblue, EGR, they works perfect for few hours or days you need to reverse the process.
