I've seen pictures of the possible location on MkV and up, but where is this elusive K / CAN gateway (Vag Com address 19) device located physically?
The following does not work in this 2003 Jetta Sedan:
Power Windows from switches inside the car
Sunroof
power mirrors
Horn
cruise control - multifunction steering wheel mounted
radio buttons on the steering wheel
Radio - which had been blinking the red light but would power on and work when you pushed the button on it... Now it is in safe mode and of course I don't have the code. It has never been moved or removed from this vehicle.
What DOES work:
Power windows from the outside key switch. Up and down. All 4 work and the sunroof closed itself at the same time.
Trunk release
fuel release
remote key for the doors
Codes have all revolved around data bus failure, from either the Can Gateway module or the instruments. New codes include "No communication" to the engine ECM and the transmission TCM.
No fuses are bad, including the two "hidden" fuses on the relay block and no change to the performance happens when disconnecting the driver's door or the 451 Multi function steering wheel module.
All of this suggests that the gateway that controls everything somehow is not working any longer. Where is the dang thing to try and replace it or swap it out?
I cannot connect at all to address 46 - central convenience. I have tried swapping the comfort module (I think this is the central convenience?) with the one from my Jetta wagon, also a 2003... No result. They have the same external part number.
