KTM told me the Ambient sensor was not reading right. It was one temperature then it dropped quite a bit. However I’ve never seen this on my dash ambient temperature display. It’s always appeared quite consistent and reliable. That’s why they suggested it could be faulty. They also said the dash display runs a little behind as there is a slight delay between the actual temp and the displayed readings. This made no sense to me and I’ve never seen this play up before or even since.Why would you change the ambient temp sensor when it seems to be working fine? It gives sensible readings, doesn't it?
