i am being hassled by my diesel particulate filters with warning messages and such and i am looking into options for the ecu to "ignore" them, shops tell me it's "illegal" or whatever for them to perform such an ecu tune. does anyone know if this can be done with vcds? does anyone in socal have a tuner? is there a way to install dummy sensors or resistors in the sensors to trick the ecu that everything is kool and the gang? thanks!
