Hi all, hoping someone maybe able to help. I have had problems with car going into restricted performance mode, various scanners have come up with Mass air flow and dpf faults. The car couldn't regen rhe dpf as it went into restricted mode. I have replaced both mass air flow sensors, have had a fluid clean through of the DPF. Problem still remains, getting a low pressure at the DPF.
I am pulling my hair out, I've now spent upwards of £350 all to no avail.
