I have a Series 3 Aero and had an issue with my speedo recently where the needle started to vibrate and slowly work its way right around the clock to the maximum speed regardless of my actual speed and then it slowly went back to zero and rested on the stop and at the same time I lost the little LCD screen with the mileometer reading on it. I kept driving for about another hour and no change. Got home, washed the car and started it to put it in the garage and all was perfect again and not had an issue since - back to the old saying of MORGAN - Most Owners Regard Gremlins As Normal. If there is an electrical issue switching the car off and leaving completely off (no ignition) for a good 10-15 minutes will ensure that there is no residual charge in any of the systems and hopefully the next time it is turned on the classic reboot will reset everything - fingers crossed.
