Long starting 2.0 TDI Skoda RS

Hello, for 2 years I have been struggling with long start-up at temperatures of 8-18 degrees. It cranks for a long time when starting, but it always comes up with no errors. I replaced the battery, sensor and fuel valve. This engine does not have a timing phaser, it is a cupa engine. Maybe someone solved the issue, now I will order a new camshaft sensor 04L907601A, currently it is 04L907601, we will see if it improves anything.
