    Hello. For about 2 months I have a problem with the engine vibrations at low speed, the matter is difficult because they are very irregular. Most often they happen after the night when I start the car in the morning, but when I drive about 1 km and stand at the traffic lights or in a traffic jam, the engine will not jump out of the frame. After driving away, driving about 300-400 m, everything returns to normal and again it goes evenly and the problem does not recur unless the car stops again, come on, it is not always there sometimes. Recently, I was able to catch computer injections during these vibrations. The engine is TDI 1.9 AWX. I attach screans from VCDS. I would ask for help in diagnosis.

    Corrections in the first scene drama. On the second, it's ok. It looks like no fuel for pushups. If a problem occurs, turn off the engine and look into the filter. Just remove the cotter pin and remove the fuel hose upwards. The fuel level is to be above the filter material. You can compare with the level of how the engine is warmed up and no problem. If it will be ok here, it remains to measure the pressure from the tandem pump, check the condition of the pump seals. You just have to remember that before replacing them you need to check whether the pumps and squeezed edges in the pump socket. As so, the new erasers are easy to damage and without making the head hard to put on new ones and in some cases it is even impossible due to the strong production of the head.

    Hello thanks for the reply. With this fuel I will check it and with the injections I will wait, maybe something will clear up. The worst thing is that it happens maybe 2-3 times a week, usually after driving a very short distance and stopping for a while after moving off, everything returns to normal. The car smokes to touch, even if it stays in the cold for 2 days, it doesn't kick, the power is not lost, everything as it was. I thought that some sensor can do it in the egg but I have no errors.

    I enclose logs from warming up the cold engine, you can see them as corrections go up to 55 degrees and later everything normalizes and the engine is running nicely. What could be the reason?
