I used to have a C3 Picasso with the 1.6 Hdi and although it wasn't too bad to drive after I had it remapped,always sounded like it was working very hard.Also I thought it was a very 'dirty' engine,the oil went black straight away after a service even using really good oil so I agree with Conor that they should be serviced every 6,000 ! I had previously owned 2x 2.0 litre diesel Vectras and a 2.0 diesel Toyota - they were very 'clean' engines (oil wise ) and I was happy to do a more extended drain interval on them.
I do not think you can beat a lazier 1.9 or 2.0 litre diesel.
edit - I believe that the suggested drain interval for the Pic was 12,500 miles - no wonder they blew turbos LOL
