Wow that is impressive,thanks MBW for the test on the VTS
Must admit i reckon a lot of people will have false alarms for the same reason as you did (ie forgetting to put the plastic card on themselves or in car)My 997s had some warranty work carried out today on front suspension squeaks and the loaned me a BoxsterS and that had VTS.The service guy said when he handed the car over please make sure you have the VTS card on you as it costs us Pounds15 everytime its a false alarm from the Police
