The problem is relatively new. Yes, this is my first diesel (or first car, for that matter). The weather here in Northern Europe is pretty cold, ca. 10 degrees Celcius, but not that cold. I drove it to Southern Europe this summer, where it got very hot! In fact, this is where I started noticing the problem.

When the car is up and running, it runs like a charm, no issues here. It is only in the first 1/2 minute or so that it sounds like it is really struggling to keep going. Once in a while during this 1/2 minute it also chokes. But apart from this it runs smooth as butter.

The engine has 325.000 km on it. It is a lot, I know, but apprx. 80.000 km's ago the engine was taken apart and got the royal treatment!
