Evening all, I'm really hoping someone might be able to help me out with a persistent DPF issue please. I am one limp mode away from bashing my head against a wall!
a few weeks ago, I had the dreaded BPW Oil pump failure...
I have fitted a recon engine, a brand new turbo, and a brand new DPF (Along with a Bosch DPF pressure sensor) and reset the ash mass calibration using my Launch diag...
After around 10-15 miles of driving, I get a DPF symbol appear on the dash, and around another 10-15 miles of driving, eventually get the flashing glow plug light, and the car goes into limp mode. When I check the ash mass in diagnostics, it usually shows between 2 to 4 grams. Re calibrating, and resetting the ash mass to zero (Knowing it really is zero as it has a brand new DPF), the car is fine again, drives and boosts well, until the fault appears again!
I have tried replacing the DPF sensor for a genuine part and I have checked that the pressure sensor hoses are clear and free of splits. The only thing I re-used from the old DPF are the metal pressure pipes, temp sensor and Lambda (Which all appear to be reading an outputting fine in live data. Pre turbo temps under full load usually hover around the 600 to 650oC mark, and settle to around 2-250 when just cruising, off boost.)
Does anyone know of anything else at all that could be causing this please, and where to look next? Thank you! 🙂
