Robust motorization

Hello, I am currently looking for a Skoda Yeti for my wife. Essentially, all-wheel and trailer coupling is required. As far as motorization is concerned, I have read something through the forum. The TSI engines are supposed to have problems with the control chain and the pump nozzle TDI motors problems with injectors. Now my question to the experts here, which engine variant is considered reliable or with which problems rarely occur? Greeting Marco
