I have had an AU 11 series wagon with dedicated gas since new and have had problems with the dashboard in the last few months. The problem has included losing all gauges, a "squeel" coming from the dash (sometimes after the ignition has been turned off) and the radio volume increasing without prompting. These problems have not interfered with the performance of the vehicle although having "gas only" is a problem without a fuel gauge working. My mechanic has run his scanner over the vehice without ay result. He has installd 2 other second hand dashes & all have had the same problem. I temporarily fix it by removing & re-installing a particular fuse, Any ideas?.
