I have a 2009 Gen III T Spirit. Recently, and I think following the recent reflash, I have been getting an extra noise on cold startup. It is a scratching noise that lasts just a couple of seconds about 4 or 5 seconds after pressingthe start button. I have tried to attach a short recording but cannot upload an mp3 file so have made it into a zip file. I have checked whether it is radio by removing fuses 8 and 28 and have also switched off the heater fan, both without any effect. Any clues anyone?
