Hello, I have a Skoda Superb 2 2.0 140 km.
I have a problem with the turbo. Namely, it occurs only in winter and at low temperatures. Exactly, after starting the car in the morning or after a long stop while driving, the turbo does not turn on. After trying to accelerate, an error appears that the boost pressure is too low. For example, when I go shopping, the engine warms up and the car stops for 10-15 minutes and the turbine turns on, sometimes it also turns on while driving. After turning on the turbo, the car has full power and the problem with the turbine disappears. In spring and summer the problem does not occur at all. I decided to clean the turbine first, but it was of no use. Today I connected VCDS right in the morning and started dynamically logging groups 003, 008 and 011. The logs show the moment when the turbo does not start and there is also a moment when the turbine comes to life and works normally. Could someone help me and tell me where the problem is? N75 valve? EGR?
