Espace 2006 2.0dci 173 Purchase recommendation

Moin people. I might want to buy an Espace Bj 09/2006 2.0dci with the 173PS. He now has almost 100,000km on the clock. It is an initial so top equipped. Well my questions. What should I consider everything if I look at it or what else there is to say about it? Are there still as frequent problems with the new diesel engines as with the old 2.2dci etc.? Do these models have any other illnesses? Driving method because of DPF is known to me. in. 30min driving, because of regeneration of the filter etc or? This engine has now also a control chain or? Is there something to consider? Vehicle is of a friendly, therefore everything should be there because of service. Thanks for the answers!
