My panamera 4s 2010 start to make that problem with the alarm, may be.
When i lock the car the hazard lights start to blink for about 5 mins. If i confort lock it (when it close all windows and the side mirrors) the hazard lights don't blink, but the interior lights (only the ones that are on the bottom) are on and the trunk light also is on. When i made computer diagnostic there wasn't any faults.
Anyone have any expirience with that kind of problem?
