I’ve had the “engine needs a service” warning a few times, always when I’ve really given her some extended thrash, as you say, turn car off and on and no trace of the warning and she runs perfect, running Ultima map, must say I have all the usual mods, Mountune induction kit, hot charge pipes, Recirc valve, but it started doing it after fitting the Cobra cat back 3” system, hadn’t done it before fitting it, so I feel it’s the exhaust that was causing the issue, I have been in Sport on all occasions too, interesting.
