peogeot 407 1.6 hdi ?

you can get a fuel conditioner which is excellent for cleaning your pump/injectors from deposits,get this at a motor factors,Forte supply good stuff part no.12200, do you have a warning light on saying DPF regeneration or something like that,if so give your motor a good run reaching top revs in 1st,2nd,3rd gears to get the exhaust really hot and this may sort your problem
