Automatic Transmission Torque Converter Problems of Volkswagen CC

I have a 2009 vw Cc that normally idles at 600 rpm but due to either engineering or a malfunction it increases it's idle to 950 rpm for either an electrical or cooling issue depending on the vw technician you talk to. This creates a situation where the vehicle wants to lunge or surge forward requiring excessive pressure on the brake to hold still. This is a 58% increase in rpm with a very low stall torque converter. The car is very hard to drive in stop and go traffic as it is surging forward and stress on the drive train at that rpm. I have taken to vw dealership, the tech agrees that it is not normal but Volkswagen of America states it is operating as engineered. If so, this is an unsafe condition to require a 58% increase in rpm for better cooling at temperatures of over 93 degrees. In any case, mine does this in the winter as well as cooler summer days and not just hot days. In fact, some hot days it does not do it at all. So either it is designed to increase rpm above 93 degrees or it isn’t. Regardless mine doesn’t operate correctly in either case.
