Dnes som dával vymenit olej pretože mi blikalo dpf na palubovke, všade som sa dočítal že by to mala byt. kontrolka signalizujúca interval výmeny oleja. Na oleji som mal najazdené cca 8000km ale pre istotu som už dal vymenit. aust_norm said: They checked it out and apparently there is a bulletin out from Subaru Australia advising of the issue which is someting called " oil dilution ". The fix is to drain the oil (I assume it was engine oil) and reset the DPF sensor. All up a 15 to 20 minute job that was done for free. Norm. The DPF light first started flashing in 2010 and I had it serviced independently. The DPF light remained flashing and my garage (I had used them for years and have found them trustworthy and reliable) advised me to take it to another independent outlet to get the DPF "regenerated", which I did. All remained well till service needed in October 2011. Join Date: Apr 2013. Posts: 7. dpf removal without an ECU remap. Hi, i recently bought a 08 mazda3 1.6d takara and within 6 weeks the dpf was was totally blocked and the car pretty much shut down (cut out after 1500rpm) and the 2 pipes with pressure sensors blew. So, my mechanic removed the dpf honeycomb with hammer and chisel, put the dpf back The DPF will undergo passive and active regeneration, as you drive. If the DPF is starting to fill up, just give it a clean (don’t wait till the ash plugs are impacted, the DPF light is flashing, and your stuck in limp mode), reset, and continue enjoying your car!!! 🙂👍 Happy Days Bro.
