The most common reason why DPF does not work are the two faults 480A and 481A. Please run a diagnostic session with Carly and clear the faults, in case you have them. Afterwards try to regenerate your DPF again.
Should you not be able to clear the faults, then please seek a local repair shop to investigate your diesel filter.
Please also ensure, that you checked these requirements as well:
- Following the Carly for BMW Instructions during DPF Regeneration
- Min. 1/4 tank capacity
- Wait a few days before you try to regenerate again
If you already purchased the DPF function and encounter problems, write us by using our contact form.
You can also send recordings directly from the DPF menu. These help with finding issues regarding DPF.
