Hi i was driving today hadn’t used car since last Sunday was on motorway slip road coming off noticed red triangle come on with no message with it car was running fine .Had to stop at traffic lights on roundabout and then light went out had only been on for a minute or so I got home put code reader on no codes either historical or new.I Had only been doing around 70 prior to slip road for about a 2 mile stretch.Started car a good few times and no code everything looking and sounding fine under bonnet .One thing normally I leave my key fob in the centre dash when I’m driving but I had put the fob in my jeans pocket which is a little tight and was wondering if my fob buttons got pressed by accident when I moved and that caused something random
