How this list lands on a ticket
Paste the codes from the scan — P2453, P2002, P0401 — not ‘a few emissions lights’. Say what you physically removed. Attach the full dump, same tool out as in.
The DTC-off option on the menu is not a ‘kill everything’ switch. It masks monitors tied to parts removed on a track or off-road build. It does not repair a dead sensor and it is not a MOT cheat.
