Did a DPF delete on my E90 320d but the car keeps going into limp mode. The tuner said he disabled all DPF-related codes but clearly something was missed.

Codes showing:

  • 4810 - DPF differential pressure
  • 481A - DPF soot content
  • 4812 - Exhaust gas temperature

Tuner is not responding to my messages. Anyone know which specific maps need to be modified to fully disable DPF monitoring on N47?

    contact your tuner first. a good tuner will check the logs and tell you if its tune-related or a hardware issue. most of the time its coincidental.

    Code 2C5A is usually a boost leak or failing turbo actuator, not related to the remap. Check your charge pipe and intercooler connections first.
