Even Peugeot 206! 1.6 HDi from 2004 and S80 DRIVe are the same engines as in the Dooper
After some research I would count:

Citroen: Berlingo (75 or 90 PS), C3, C3 Picasso, C4, C5 !!, new DS3

The DLD-416 (or DV6) is a 1.6 L (1560 cc/95 cu in) 90hp or 110hp version also used by Ford, Mazda, Volvo, Mini, Peugeot and CitroŽn. This particular engine was designed by Peugeot engineers on behalf of PSA and Ford. Due to high demand, it is currently (2008) being produced in both France and England.
