I have a 2020 s3 with the second generation obdeleven, I need some help, why does everything I try to do either says fails or doesn't let me accept the coding or setting I input,as for Apps it say not supported on almost all of them and the ones that do load wont let me change anything just spins and says "something went wrong,try again" , long coding wont let me hold the green check i press it and hold it spins but doesn't save the option , and anything I change any other way says loading the circle spins then says failed. It feels like something is blocking the obdeleven from communicating with the car like a wall. Please help!!

Try opening the bonnet first - newer cars have a CAN bus firewall, and that is pretty much the symptoms you’ve described!

I just joined the forum and am a new OBD11 user. I have a 2019 A3 using an OBD11 new style device and also couldn't get the apps to work. After opening the hood it works properly. Thanks for those that suggested the fix.
