not sure about diags on diesel BMW's but that looks to me like the computer has disabled the injector on #6
When the cylinder contribution test shows the bar in the far right that means that cylinder power stroke is accelerating at a much slower rate relative to the contribution of other cylinders. also the photo OP added is not helping himself, post the entire screenshot with all the rest of the cylinders

Looks like you have a leaking injector....

Like said show us the values on all cylinders. Which injectors were refurbished and was it a reputable shop with proper test bench? If the correctional value is very high and the injector is 100% OK it would unfortunately indicate a compression issue on that cylinder.
Correctional values and injector leak don't have a direct correlation. Correctional values tell more about the condition if the injector nozzle (atomisation). Leak off (internal sealing failure) will show as slow/no start or low rail pressure on heavy load.

All other cylinders are in the middle, only cylinder number 5 is in red. All injectors were repaired and the machine proved to be good. After I put these repaired injectors in the vehicle and saw that I had a problem again, I took off the injectors for the vehicles again and took them for inspection and it was shown again that the injectors are all right.
This problem with smoke is not only when the car is completely cold, but also when it is at a medium temperature (slightly below the working temperature). When it is at operating temperature (90 degrees) after a long work in the place you can smell the stench from the exhaust but no smoke Sent from my iPhone using Tapatalk |

Question - did you put each injector back in the same cylinder as it was removed from - both times?

I did not return it to the cylinder from which it was taken, but each injector was coded after return. To note I had the same problem before repairing the injectors. After repairing the injector, it works better, but I still have this main problem. at higher revs cylinder number 5 enters the green field on the diagnostic

I bought the car with this problem (because I didn't know), the man I bought it from told me only with the turbo changed. The car really has no problems with ignition, it goes as it should, the oil does not run out at all ... Could the compression measurement show something or how to check if there is a problem in the computer as stated above by a colleague
