Timing belt change? Hello. I've just purchased a Skoda Yeti 4x4, 2009 model, 2.0 diesel, 140hp, from Germany. It has 148000km and the timing belt and water pump have not been changed because in Germany there is no time limit for changing them, only km, respectively each 210000km. In my country (Romania) Skoda dealers advise changing them every 210000km, or every 5 years, whichever comes first. So, which is it? Doesn't the rubber in the timing belts get fragile with age? I was taught that age is relevant, and timing belts should be changed every 5 years (4 initially). And when should the oil in the gearbox and differentials be changed? Help please. Thank you very much.
