Last Friday having travelled 3 miles in my 6 month old gti pp dsg, switched ignition off and then did shopping for 2 hours, on my return switched ignition on, the radio worked but screen was blank and not responsive to any touch screen therefore no telephone, apps etc and could not change to another radio station. Reverse camera on screen worked OK. On my return home switched ignition off for 10 minutes then switched ignition back on and the screen worked normal and has worked normal ever since. I phoned my local VW dealership, spoke to service department manager who suspects computer update is required. Car goes in to dealership Monday morning. Has any fellow forum member experienced this issue please, cheers.
