Audi A3 2.0TDI BKD - Unequal Idle Performance, Issues in Pump Units 2, 3 & 4, and Injection Fixes

Hello. The car is working poorly on idle, the errors are missing, the only thing that can be linked is during uneven work 2, 3,4 pump units shows values indicating the lack of connection with the pump. Earlier, someone named the injection 1 because it fell completely. Now the first one works the best.
This uneven work occurs only at idle. Improved pins, cube on the head cleaned with an electron preparation. I can check the oscilloscope and pumping in the circuits and exclude space 1 from eg 2 But this is unnecessary cost and I do not know how the sockets look (who was there who fumbled).
Anyone had a similar case?
Maybe just the sealants fell but the beeps are ok on the 1st cylinder (where the interruption of the injection) the corrections are negative in 013. The car does not kick after heating works perfectly. I have not seen any other suspect parameters except maybe a strange dose (too low = high) but this may be due to interruption and somehow trying to keep it running.

Did you regulate the pump pumping loses?

Subject is overwhelmed. On the first cylinder of pumping engines also began to cut off.
I have improved the timing and so far the car is working perfectly apart from the sometimes twitching twin. The inflatable pumps in 018 do not even stop for a moment. Strange as if the computer tried to suppress the engine by shutting the pump-jets. In 004 I had almost perfectly adjusted roller correction. In the car it was said that the timing was replaced recently and they did it inaccurately

Hello. Was not this equal to idle work on a warm or cold engine? I have the same problem as the engine will warm up and at idle, feel the vibrations on the cold engine working evenly. Skoda octavia 2.0 tdi BKD.

Unfortunately, I do not remember. Possible with heat. Check the timing is 5 - 10 minutes or maybe 15. In my case, I had an exhaust after setting the game like this doll. After corrections and beauties, everything looked okay.

Thanks for the answer. I still have a few questions about which year do you have a car? What mileage? , a two-year-old made? and injections? Thanks in advance for all these answers. Greetings.

The car was a customer. I gave up and goes to today. Twelve did not really do.
