January 23, 20197 yr Hi I desperately need some help. My car is currently in the garage and they have phoned me to say that my Legacy still isn't working. The problem he said was this: DPF pressure sensor has been replaced. Fault code DPF LIMPHOMEMODE Soot contents level 154% But they have blown air through the pipes and it's flowing through nicely so the pipes are clear. They are looking for someone who can get an override code? Many thanks in advance Karen
January 23, 20197 yr Author I think if I have understood it correcty, that when the garage plug in diognostics (because the lights on the dash are still on) it comes up with DPF LIMPHOMEMODE.
January 23, 20197 yr Author It's gone to far for a forced re-gen. We need some software to tell the ECU to go back to factory limits due to pressure sensor failure. The DPF is cleaned and fine.
January 23, 20197 yr Author 3 hours ago, Mr B said: what is the actual present code/codes numbers .... Soot > 135% – DPF Limp-Home Mode = DTC P1469 or P246C: DPF light flashing: and MIL on: .
January 23, 20197 yr At 135% the ecu will not allow regen without tricking it and it need be told new DPF fitted . You'll want change oil and filter too as half reason engines go bang is dilution of diesel from dpf regen cycles . dpf is a engineering disaster and worse for environment over vehicle lifespan than pre dpf diesels ...
January 23, 20197 yr Author Yes that's what garage are saying, but we don't know how to trick ECU, or rather what the software is called and where you get it from.
