Mine has a squeaky rat behind the speedometer.....I notice this since I bought my zed 116 months ago. I knew where the noise is coming from as I managed to stop the squeak whilst placing my hands in the gap between the speedometer and the dashboard, a bit of pressure on the panel stops it. If I can wedge something there it should stop it but won't look nice =) I did spray some PTFE lubricant but it did not managed to get into the area where all the squeak is generated. Try spraying some, might reduce the squeak when its less friction
