fault codes take 3 cycles of ignition to store a cel on the dash, so it might come back

Oh dear.I have a feeling that this is going to cost me. Three days into f***ing ownership
(This may simply be due to a required oil change, as the fault codes have not returned during todays driving - (for any future search results))
