I found a used orange direct VW TPMS kit on Ebay, the seller said it works great, but I'm having trouble getting it to work. I've followed the instructions carefully, and used the coding dongle/receiver in the OBD II port with the ignition on & engine off, never with engine on, in every different combination:
-ignition on, followed by coding dongle & receiver plugged into OBD port
-ignition on, followed by coding dongle plugged into OBD port, followed by receiver connected to coding dongle
-coding dongle & receiver plugged into OBD port, followed by ignition on
After that I've connected the receiver to the gateway controller in the vehicle and it all connects together fine, but then the infotainment readout looks the same as before, where you can just set the tire pressures, without the individual readouts.
Does anyone have any tips? Can the coding dongle only be used once (in this case by the Ebay seller), and then it can't be used again on another vehicle? Does the display only update to the individual readouts, once the sensors are installed in the tires - but before the sensors are installed, it will still look like the old system? Should I run the engine while the coding dongle/receiver are in the OBD port? What am I missing here? Thank you in advance for your help
