Almost every journey I make under acceleration I get smoke coupled with "Unblock Diesel Filter" error on screen. If I continue that accerlation then I will get another error "Anti pollution Fault" and the car will go into limp mode until I cut the engine for a couple of minutes. If however I ease up to around 1k revs after the first error then it will clear after about 1 minute. I have completed a force regen using pp2000 as well as static manual regen and regular bypass journeys to complete a regen and it doesn't help. I have also used plenty of DPF regen fluids in the fuel and also have the Additive tank topped up and ECU value reset despite it already being 3/4 full. When the Turbo kicks in its noisy like air rushing (a couple of mechanics have noticed this but have no suggestion) however there is absolutly no loss of power. I am wondering if these things are related and what can be checked to find the problem. I have a Peugeot 307 SW 110 HDI 2 Litre 2002 (52 Plate) around 110k miles.
