First code on stock MY18 (Mountune V2x exhaust only). Same code last week and the dealership cleared it. Said maybe a glitch. Came on again yesterday during a very short burst of WOT. She's been sitting a lot more then usual and only take her out 2 days out of every 14 for some aggressive cruising. I've also been keeping the tank at 1/2 or less so as to not let the fuel sit too long in the tank.
Booked in for Monday at the dealership.
