Cleaning the diesel particular filter (DPF) on a 2005 tdci ford focus with great results.The vehicle would not regen as there were fault codes relating to a blocked DPF, the vehicle was also in limp home mode ( reduced power) The codes would not clear,so we hooked up the DFS910 machine and let it do its magic,45 minutes latter we were able to clear the fault codes and take it out of limp home mode and also force a regen with are ford ids tool and hey presto all running great again and one very happy customer.
