Ever since I had my Jazz 2017 MOT'd and serviced last week it has had warning sign come up on the right of the dashboard. It is a yellow dial, similar to the outer edge of a clockface, with a single hand/marker pointing to approximately the left. On the left, outside the dial, there is a yellow rectangle/square with the number 1 in it. It comes on mostly after I have gone round a roundabout then accelerated out of the roundabout. Normal speed, not fast. It happens occasionally at other times too. I rang the garage who did the work and the guy I spoke said he knew what it was, something quick that he just needed to do, and just pop back in any time. However he has gone off sick and nobody else there knows what it is. A test drive didnt replicate it yet it still happens when I drive it. I cannot find the symbol online anywhere. Does anyone know what it is please?
