The very instant I touch the sign in button.
The first thing to try is disconnecting one of the battery cables for a couple minutes to reboot the TCU.
Go into the CarWings settings in the NAV system and look at the Unit ID info. The telephone number should be 4 asterisks (****), and the other 4 lines should be populated with characters. If the VIN number does not display correctly, then the dealer tech did not follow the proper install procedure. If so, refer them to Campaign Bulletin PC449/PC450 dated 17 November 2016 for the correct install procedure. The upgrade process includes programming the new TCU with the Consult tool, and several calls to register and activate the new unit. The tech also needs the IMEI numbers off both the old and new TCU to complete the process.
It could also be that you are one of those suffering from the low voltage issue with the 12 volt battery that causes the new TCU to go into standby mode. Open the hood on the car and let it sit for several hours turned off. Do not open the doors, use the remote, connect or remove the charge cable, turn it on, or have anything connected to the OBD port. Check the voltage level on the 12 volt battery after it has sat untouched for several hours (overnight is better). If it reads below 12.5 volts, then you have a battery that possibly needs replaced. You can try checking the battery cells, topping them off with distilled water, disconnecting it from the car and giving it a full charge with an external charger. If the 12 volt battery is more than 3 for 4 years old, it might be better to just replace it.
