For those of you who want to know the serial code on your wheels to swap wheels and can’t wake them up by deflation or spinning, go to your local Kwik Fit garage and ask them to use there tool for reading tyre pressure sensors, it will only read cars so tell them to try Vauxhall Astra either 2010 or 2008 on which is “J” or “H” models worked perfectly on my 2015. It will give you the serial number so you can type that in to the GS-911WIFI.
