V50, 2.0D really that bad?

Hello, I’m going to buy a new car in the next 12 months. Maybe it should be a V50, 2.0D. Now I’ve read here that there are many problems with the 2.0D, but they should be fixed from MY08. Can you say now if that’s true? Where were the problems exactly? I drive about 20,000 km a year, there is actually only one diesel in question for me. We “repair-friendly” is a V50 actually. Can you change the light bulbs yourself or do you have to go to the workshop for it? Drive it only in contract workshops or is the car in a free workshop just as well. The next dealer is 30 km away from me. Greeting, Peter
