Hey, new to the group! Was looking for a parts or Caddy forum but count find one.
I recently did some work on a 2006 Caddy of mine after a coolant leak (which is all sorted now) but I now have a U0103 - lost comms w/ gear selector module - code. Still not sure if it was from disconnecting the battery or coolant getting into a connection… Have done a fair bit of digging around, but am looking at replacing the gear selector module. Annoyingly I can only find a second hand one that isn’t the exact same part number, although it physically looks identical. The part numbers are 1T2713025R (mine) and 1T1713025R (also from a Caddy). Would anyone know if these two would be interchangeable, or is there a big chance the electronics wouldn’t communicate?
Any help greatly appreciated!!
