If we were talking older diesels, I would say they are fantastic. The newer TDIs, along with VWs lack of quality control and their poor electronics, make this, and any other newer VW, a nightmare. My personal experience is as follows; I had one blow up at 110,000km. Oil changes run about $300+, turbos last less than a year, and the CEL is almost always on. Add to this the electronic gremlins, and it's just not worth it.
