There is no such thing as a "tune up" on a modern car, most especially a diesel. This term refers to the old engines that required, points, plugs etc.

I do not what you are asking, however, and it sounds as if you have the bases pretty well covered.

Once you have all this done and it is running to your satisfaction, it will be time to start being religious about oil and filter changes. I don't want to start an oil war here, but use a "Universal Grade" oil. These are designed for diesels and have additional additives to deal with the soot that is generated by a diesel. Examples of these oils are: Chevron Delo Multigrade, Shell Rotella T, Mobil Delvac and there are many others besides these most common ones.

Change oil and filter frequently and thoroughly and maybe you can get 380,000 miles out of the engine as I did on the original engine in my 240D.

Enjoy,
Change oil hot and change oil often,
