Hello, newbie here. I just purchased an 04 Cayenne S 4.5 with 90 K here’s the issue. Put key in, hold brake, turn key, car starts great. Shut car off, try to start again, will not turn over. All lights come on, column unlocks, ect. Let car sit for an hour, starts right up. It doesn’t seem to matter if it runs fir 30 seconds or two hours, will not start unless it sits. Was told to change battery in fob. No difference. First Porsche. Please help.
