I tried to set up the former but the car doesn't appear to recognise the number I put in - I have a feeling that the PIN is still perhaps locked with the number the previous owner user? If that's the case how do I get access to change the PIN when the car isn't registered on the Tesla app yet? A further question - driving today I have somehow managed to set Valet mode....it appears that Valet mode has its own PIN number distinct from the PIN used to allow the car to be driven. No idea how I got into valet mode but now I can't seem to get out. Is this another thing I need Tesla to unlock whenever I can actually get the car added to the App? Thanks
