I have a 2009 Q5 with the Thermo Cup Holder and I am having an issue with it. Whether I turn on the heating or the cooling after a short amount of time(about 25-45 seconds), the selected setting ceases to work. If I try to turn it back on the indicator light just blinks repeatedly. The only way I have found to get it to stop is to turn the car off then back on again. Then the process begins all over again. Does anyone happen to know what the source of this issue is? Any insight would be much appreciated!
