Yes,there crap. Once the turbo go's the whole engine is pretty much scrap. We now turn them away and were a ford dealer. Even if you clean all the filters out they still go again. If its a 110ps they have a dpf on them that needs replacing every 75000 miles and the dpf fluid topping up every 37500 miles. Engines can get very noisey over time from the top end. Just because your going to maintain it doesn't mean the previous owner has. They hate short journeys and will sludge up the oil pretty quick.
