Your salesman's advice is pretty good. Your owner's manual should also have some general advice under "breaking-in" the engine. Lot of people don't believe in it, but I sure don't think it hurts and it may make a difference in the long run. FWIW I had a 335d (same engine?) and it burned a little oil during the first couple thousand miles, then stopped burning oil completely. Metallurgy is different in the diesels. Really takes a long time before the engine is really broken-in, I think. I also have a VW TDI diesel sportwagen and the gas mileage has gradually increased by around 4 mi per gallon as the engine has loosened up some (at 45k mi now) and according to the TDI forum I may see another gallon or two increase until 60k mi when the engine can be considered broken-in.
