Just finished servicing a 1.6hdi. Check the mileage. Its getting a bit rattly but its going good. The service interval is set to 15,000kms. Smaller service intervals are the trick to longevity on this engine for sure.
Last night I was reading an old AA drivers handbook from the 1960s. It was amazing the wealth of information in there that's no longer passed on. OK, some of it might be irrelevant now (such as the running in of a new engine and changing the oil at 100, 500 and 750 miles - yes I did say 100,500,750!)
But it reminded readers that cars doing short distances should have more regular oil changes.
