DPF regen woes continue.
The story so far.
My car regens its DPF every 70miles.
All star diagnostics chek out ok apart from MAF which is slightly over reading.
DPF replaced (too full of Ash) under warranty.
No change to frequency of regen.
Changed Diff pressure sensor. No change to freqency of regens.
ECU is now main suspect. Can anyone think of any other thing that might be causing this to happen?
Why would the ECU call for a regen when it's getting all the right info and I know the DPF is clear?
Thanks,
