DPF Regeneration Conditions

DPF Regeneration Conditions

All guides/tutorials are intended for educational purposes only. If you follow any of the guides/tutorials, you do so at your own risk. We accept no liability and/or responsibility for any damage or otherwise that may be caused to your vehicle/belongings/possessions.

If you have a DPF (Diesel Particulate Filter) warning come up on your iDrive/cluster, ensure that you are able to regenerate your DPF by meeting all the conditions below. 


    Your BMW needs to meet a certain subset of criteria in order to regenerate. If any of these conditions aren't met, you'll block the DPF and ultimately need a costly replacement. 


    Check that you meet the following when attempting a regeneration. 


    • The coolant temperature must be in excess of 75 °C
    • The exhaust-gas temperature before the diesel particle filter must be greater than 240°C
    • There must be enough fuel (recommended at half a tank). Whenever the reserve lamp lights up, the regeneration process is suspended
    • No fault codes from the air mass system, exhaust emission system and sensors must be saved in the DDE
    • The fault codes 480A / 245700 (from F01) and 481A / 245800 (from F01) must display the status "currently not present"
    • Constant driving speed above about 60 km/h (approx. 38 mph). The optimum speed is about 100 km/h (approx. 60 mph).
