M57 30d DPF done for? Screenshots provided

czrny · 10-07-2024, 05:59 PM

I have '07 e92 330xd which still drives great after 250kkm except for DPF issues - getting DPF regeneration request almost immediately after regeneration finishes.

I did DPF adaptations reset to get rid of dashboard errors - no improvement.

Here are DPF pressure and back pressure values while stationary - screenshots.
I also did dynamic logs - max 350 hPa backpressure during max load - last screenshot.

All seems to be within max permissible values.

Don't know what to do next. Anyone?

Hello what diagnostic program do you use

What is your ASH measurement? There is an end of life code for the DPF that the DDE will present but as long as your DPF is still functioning it is still fine to use. Most importantly what is your coolant temp at full operating temperature? should be 90C and higher during regeneration. 2PSI at 4krpm is higher than normal
