Update: There is no any cracks or holes in intake system. All good and tight with it. I don't know what to check now ...

Unfortunately, I did not follow any rules when this error occurred. Sometimes it appears after 300 kilometers from extinction. Sometimes after 50 kilometers. Regardless of the level of fuel in the tank, engine temperature, outside temperature, speed or RPM. The only "pattern" that appeared was when it was detected that one of the wires leading to the turbine was cracked, which caused a weaker charge. After replacing this cable, the error (p0171) was lit non-stop for some over 3,000-4,000 kilometers until I changed the top oil separator. Then the situation returned to the point where the error occurs and disappears from time to time.

It was also replaced to. :/ I'm going to the workshop on Thursday. We check the tightness of the intake system. It will be the fifth workshop in two years. Skoda authorized service was the first to give up.

Thank You for replay ! At the weekend I tried to check the things you wrote about. Unfortunately, as we say "I have two left hands" when it comes to mechanics. The only strange thing about the intake system is the "moisture" that can be seen in the pictures. I have to go to a professional workschop to check the tightness of the intake system.

Welcome ! At the beginning I am sorry in English and with errors. After two years of fighting (with breaks) I decided to ask at the source :). Skoda Superb 2.0 TSI with DSG. From two years, from time to time Chceck Engine control appears with error P0171. In addition to the appearance of the light itself, the car behaves completely normally. Therefore, I want to sell the car. I decided to remove the "failure", unfortunately it did not turn out to be easy. During this time I have already replaced: - Lambda probe - Spark plugs - Fuel filter - Engine odor (crankcase breather) - Fuel tank vent valve - I have also updated the main computer and gearbox driver software Unfortunately it did not give any results and the error keeps coming back. Has anyone ever encountered such a problem? Thank you in advance for all suggestions. greetings Maciek
