SUV or combo up to 20,000€ searched

Hello, I am looking for a (planned) family car and would be willing to spend a maximum of about 20,000 € for it. I really like the Audi Q3 and the VW Tiguan, but I have no idea which engine would be better and if possible a combination would be better (and if so, which one?). I drive mainly to work by car (about 45km a distance, almost only motorway on which one – thanks to the Rhine-Main area – actually never drives faster than 130 km/h – mostly more like 100 km/h). km/h) and sometimes larger routes during holidays, family visits etc. Is it worth a diesel, even with a view to the current loss of value? At the Tiguan 1.4 TSI I read, the engine is quite a problem (combination of turbo and compressor has already caused me an engine damage with my current car after 85,000km…). Important would be a good reliability. I am happy about your ideas and suggestions!
