I have a VW Golf with the TDI PD engine. I bought it brand new in 2001 and have had it ever since. The low oil warning light came on after about 4,000 miles and for about the next 30,000 miles I had to top up between services (10,000 intervals). It has now done 60,000 miles and now hardly uses even a drop of oil. It runs very smoothly. I think diesels are just about run in at 50,000 with an easy 250,000 plus miles ahead (look at taxis and lorries). I suspect your TDI is just fine and is bedding in.

My dilema now is whether to service it myself as I am pretty fed up paying VW nearly 200 quid for an oil / filter change and a couple of other filters which simply clip out - oh and a lub of the door hinges. Those shinny glass palaces at main dealers cost a fortune and it is these and their company cars we all contribute to - yet cars are so much simpler to service compared to the days of points, tappets, pedal adjustments, etc. There is only about 30 mins of semi skilled work today and the essential parts are just 3 filters (oil, air, diesel and rather expensive engine oil). Legalised rip off to stamp the book.
