If you have the DPF warning light on your BMW X_E70 dashboard, it could get expensive. The warning light indicates a buildup of soot which is not being burned correctly in the DPF system in your car. Your manufacturer owners handbook should show you how to burn off the soot in the DPF, however on many occasions it simply does not work.
A BMW Diagnostic tool is the answer to doing a forced regeneration. With the Foxwell NT510 scanner, DPF Regeneration menu let you perform the DPF cleaning to clear the blockage through continuous burning of the particulates captured in the DPF filter. When a DPF regeneration cycle is completed, the DPF light automatically goes off.
