1.5 Dci – 82 HP – Life expectancy

Hello forum. I drive a Thalia with 1.5 Dci and 82 HP. Recently I crossed the 180tsd and the car runs like new. I drive almost only overland and hardly even faster than 120. Since I think about doing something else on the car I would be interested in what you can expect from KM – performance so and what experiences others with this engine and high mileage have already done. Also I would be interested if you can still chip tune even with higher KM – stand. I don’t race, but if I overtake on the road I would like a little more reserve …
