Hi All,   Pulling my hair out again with DPF.   Purchased Octy CR170 last November knowing it had DPF delete and remap .... due to DPF filling up to a level whereby needed a new one at cost £900 by previous owner (i was assured its passed each MOT no worries)   Cue my failed MOT yesterday for DPF Tampered on visual check however they never tested the emissions(stating didnt want to put it under load as low oil - oils fine). Halfrauds quoted £1070 ! On a car i paid £
